Abstract:
<i>A line follower robot is a mobile machine that detects and follows a line drawn on the floor. By and large, the way is predefined and can be either noticeable like a dark line on a white surface with a high differentiated variety or it tends to be imperceptible like an attractive field. Definitely, this kind of robot should sense the line with sensors that are installed under the robot. The data from the sensor is sent to the driver and thus the path will be followed by the line follower robot. Additionally, a microcontroller could be used to analyse data from the sensor and provide appropriate commands for the driver. In this work, a simple line follower is constructed without a microcontroller.</i>

Abstract:
The purpose of this research is to analyze the relationship between the intensity of light hitting the LDR to the resistance and the flame of the light. The research created an automatic lighting system, in which the lighting system was designed to turn on or off lights by light intensity. This research created automatic light controls using LDR light sensor. The LDR light sensor set is used as a switch that turns on or off a light automatically based on the recieved of intensity of light. By using the LDR components, it can design a series of light sensors for such items as outdoor light sensors, sleeping lights, garden lights, road lights that turn on at night and go out during the day automatically. The equipment used of the research were 2 test lamps, and done with 2 lighting sources, a natural source of lighting and an artificial source of lighting. From the research, it showed that the large light intensity affects the light flame by using LDR light sensor. It could be concluded that the greater of the light hitting intensity from the LDR surface was smaller than the value of the resistance and the flickering of the light. In contrast, the less light that affects the LDR, was the greater value of LDR resistance and lighter the light.

Abstract:
Abstract— Indonesia is a country that has a diversity of flora, one of which is ornamental plants. The types of ornamental plants are very diverse, one of which is the mother-in-law's tongue plant. Each plant has different needs for growth depending on the ornamental plant, starting from the need for water, soil moisture and sunlight. Based on these influencing factors, if it is not suitable, the ornamental plant will die, and this will also happen to the mother-in-law's tongue plant. Therefore, research entitled "Automation of Monitoring and Watering Mother-in-Law's Tongue with LDR and Soil Moisture Sensors" was carried out to overcome this problem. This system requires several components including a mother-in-law's tongue plant, Arduino Uno, LDR sensor, soil moisture sensor, I2C LCD, relay, and water pump. The way this system works is that the LDR sensor detects how much light is around the mother-in-law's tongue plant, while the soil moisture sensor measures the condition of the soil on the ornamental plant, namely the mother-in-law's tongue. The monitoring automation is based on the LDR sensor and soil moisture, while the watering automation for the mother-in-law's tongue plants is based on the soil moisture sensor. The results of this research prove that on an LDR sensor, the more light the resistance value of the LDR sensor will decrease, and vice versa. Meanwhile, the soil moisture sensor proves that when the soil humidity is &lt;300, the water pump will turn on, and if the soil humidity is &gt;300, the water pump will turn off automatically. If this system is applied to everyday life, it will be very efficient because it saves energy and time. Abstrak— Indonesia merupakan negara yang mempunyai keragaman flora, salah satu nya adalah tanaman hias. Jenis tanaman hias sangatlah beragam, salah satunya adalah tanaman lidah mertua. Setiap tanaman memiliki kebutuhan untuk tumbuh yang berbeda-beda tergantung dari tanaman hiasnya, mulai dari kebutuhan air, kelembaban tanah, dan cahaya matahari. Berdasarkan hal-hal yang mempengaruhi tersebut, jika tidak sesuai maka tanaman hias akan mati, begitupun akan terjadi pada tanaman lidah mertua. Oleh karena itu, penelitian yang berjudul “Otomatisasi Pemantauan dan Penyiraman Lidah Mertua dengan Sensor LDR dan Kelembaban Tanah” ini dilakukan untuk mengatasi permasalahan tersebut. Sistem ini membutuhkan beberapa komponen diantaranya adalah tanaman lidah mertua, Arduino Uno, sensor LDR, sensor kelembaban tanah (sensor soil moisture), LCD I2C, relay, dan pompa air. Cara kerja dari sistem ini yaitu sensor LDR mendeteksi seberapa banyak cahaya disekitar tanaman lidah mertua, sedangkan sensor kelembaban tanah untuk mengukur keadaan tanah yang ada pada tanaman hias tersebut yaitu lidah mertua. Otomatisasi pemantauan berdasarkan sensor LDR dan kelembaban tanah, sedangkan untuk otomatisasi penyiraman pada tanaman lidah mertuanya berdasarkan sensor kelembaban tanah. Hasil penelitian ini membuktikan bahwa pada sensor LDR, semakin banyak cahaya maka nilai resistansi dari sensor LDR akan semakin turun, begitupun sebaliknya. Sementara itu, pada sensor kelembaban tanah membuktikan bahwa pada kelembaban tanah &lt;300 maka pompa air akan menyala, dan jika kelembaban tanah sudah &gt;300 maka pompa air akan mati secara otomatis. Sistem ini jika diterapkan pada kehidupan sehari-hari akan sangat efisien karena menghemat tenaga dan waktu.

Abstract:
&lt;p&gt;Intelligent electronic systems are increasingly prevalent in modern society. The development of smart bedrooms for young children, especially those with developmental disabilities, it is based on the responses of passive infrared (PIR) and light dependent resistor (LDR) sensors. The PIR sensor detects children’s movement during the night, triggering the microcontroller to send a bit of 1 to the microcontroller pin connected to an electromagnetic relay, which then switches on a 220 VAC light to illuminate the bedroom. This only occurs if the LDR sensor has high resistance, indicating that the environment is completely dark. The functionality of this intelligent system mainly depends on the program code (sketch) uploaded to the Arduino UNO microcontroller module. The microcontroller is programmed to perform specific functions based on the sensors data. It is based on the responses of PIR and LDR sensors. The PIR sensor detects children’s movement during the night, triggering the microcontroller to send a bit of 1 to the microcontroller pin connected to an electromagnetic relay, which then switches on a 220 VAC light to illuminate the bedroom.

Abstract:
At this time, almost all Public Street Lights (PJU) still use the type of mercury and SON-T lamps, even though the mercury and SON-T lamps absorb a considerable amount of electricity. Public street lighting is usually on almost all nights, and this is a waste of electricity. Public street lighting is usually on most nights and thus is a waste of electricity. Usually, when it is past midnight, the streets are quiet, so the street lighting should be reduced in intensity to save electricity. Based on this problem, this research uses an experimental method (Experiment) to create a design to make efforts in saving electricity. The method used includes electrical and systematic design. The steps taken include the stage of literature research, designing, manufacturing hardware and software, integrating the system, and testing and analyzing the system. Considering these theories, we can know the programming of the microcontroller ATMega 328, Photocell Sensor, PIR Sensor, LED Lights, and Power Supply. This research using several tests, including testing Photocell Sensor, PIR Sensors, LDR Sensors, and LED Lights. Photocell sensor to detect conditions day or night. PIR sensor functions to detect movement, LDR sensor to detect movement, LED lights are used to increase and decrease light intensity. For all the tests above, the results obtained when the PIR and LDR sensors have not detected any movement will dim the intensity of the LED lights. After the PIR and LDR sensors have detected the movement of the LED lights, they will turn automatically bright.

Telah dibuat alat pendeteksi intensitas cahaya berbasis Sensor Light Dependent Resistance (LDR) dengan modul arduino Nano V3. Alat ini dibuat dengan memanfaatkan perubahan resistansi pada sensor LDR ketika dikenakan cahaya. Sensor Light Dependent Resistance (LDR) ini belum dikalibrasi sesuai standar pabrik, sehingga digunakan alat ukur intensitas cahaya luxmeter L200 yang sudah terstandarisasi untuk proses kalibrasi alat. Alat kemudian di program dengan software Open-Source arduino agar hasil pembacaaan alat dapat ditampilkan pada layar LCD 16x2. Hasil yang didapat yaitu pada saat belum terkalibrasi, alat luxmeter berbasis sensor LDR ini pembacaannya berbeda jauh dengan Luxmeter yang terstandar berkisar antara 1:1,5 dan setelah dikalibrasi error yang dihasilkan pada sensor ini mengecil dan pembacaan sensor LDR mendekati dengan alat ukur luxmeter L200 yang sudah terstandarisasi.Light intensity detection devices have been developed based on Light Dependent Resistance (LDR) sensor with arduino Nano V3 module. This tool is made by exploiting the resistance change in the LDR sensor when it is applied with light. This Light Dependent Resistance (LDR) sensor has not been calibrated to factory standards, so a standard L200 luxmeter L200 intensity gauge has been employed for calibration process. The tool is then in the program with the arduino Open-Source software so that the reading results of the tool can be displayed on the 16x2 LCD screen. The results obtained when not yet calibrated, are differ greatly with the standardized Luxmeter which ranged from 1: 1.5 and after been calibrated the error result in this sensor is become smaller and the constructed LDR sensor readings are close to standardized luxmeter L200.

Dissertação para obtenção do Grau de Mestre em Engenharia Electrotécnica e de Computadores<br>O rápido desenvolvimento da microtecnologia e microelectrónica tem vindo a contribuir de forma decisiva para uma crescente utilização de sensores, sejam eles com ou sem fios, o que permitirá interagir mais eficientemente com o meio envolvente, em consequência de mais e melhor medição e atuação. Neste contexto, as redes de sensores sem fios (WSNs) estão a emergir como uma das grandes e mais importantes áreas das telecomunicações e aplicações de monitorização e controlo. Neste tipo de redes, os terminais remotos com sensores têm que operar em condições físicas diversas e obedecer a restrições no que toca a consumo de energia e factor de forma, e ao mesmo tempo providenciar automaticamente a sua geolocalização precisa. Por outro lado, todas estas características devem ser implementadas a custos reduzidos e do ponto de vista da sua autonomia energética, a mais prolongada possível. Em relação ao primeiro requisito, a implementação em tecnologia CMOS integrada permite reduzir substancialmente o custo. Para cumprir o último requisito, dado que este tipo de aplicação não requer taxas de transmissão muito elevadas, é possível optar por uma arquitectura simples baseada em impulso rádio através da transmissão de largura de banda muito grande (ultra wide band - UWB). Esta aproximação pretende responder à necessidade de se reduzir e optimizar o consumo energético associado às comunicações em radiofrequência. Esta dissertação apresenta assim um sistema de UWB para transmissão e recepção de dados, a curta distância, projectado em tecnologia CMOS, focando a optimização dos índices de consumo energético.

Abstract:
Flow rate measurements are a common topic for process monitoring in chemical engineering and food industry. To achieve the requested low uncertainties of 0:1% for flow rate measurements, a precise measurement of the shear layers of such flows is necessary. The Laser Doppler Velocimeter (LDV) is an established method for measuring local flow velocities. For exact estimation of the flow rate, the flow profile in the shear layer is of importance. For standard LDV the axial resolution and therefore the number of measurement points in the shear layer is defined by the length of the measurement volume. A decrease of this length is accompanied by a larger fringe distance variation along the measurement axis which results in a rise of the measurement uncertainty for the flow velocity (uncertainty relation between spatial resolution and velocity uncertainty). As a unique advantage, the laser Doppler profile sensor (LDV-PS) overcomes this problem by using two fan-like fringe systems to obtain the position of the measured particles along the measurement axis and therefore achieve a high spatial resolution while it still offers a low velocity uncertainty. With this technique, the flow rate can be estimated with one order of magnitude lower uncertainty, down to 0:05% statistical uncertainty.1 And flow profiles especially in film flows can be measured more accurately. The problem for this technique is, in contrast to laboratory setups where the system is quite stable, that for industrial applications the sensor needs a reliable and robust traceability to the SI units, meter and second. Small deviations in the calibration can, because of the highly position depending calibration function, cause large systematic errors in the measurement result. Therefore, a simple, stable and accurate tool is needed, that can easily be used in industrial surroundings to check or recalibrate the sensor. In this work, different calibration methods are presented and their in uences to the measurement uncertainty budget of the sensor is discussed. Finally, generated measurement results for the film flow of an impinging jet cleaning experiment are presented.

Being aware that one may only capture senses by placing them within their own constitutional process, this work has endeavored an analysis format that articulates the particular to the whole, meanings to the social and political dimensions of our material reality and to the knowledge that is produced in the area so that we may act upon senses. It has been pursued in this process to assess whether these senses are operating to support the dominant conception of literacy or whether they have been assuming a role of social transformation agents. The chosen method was the Dialectical Historical Materialism and the information herein has been produced by the means of a conversational dynamic as proposed by González Rey. The applied tools were a checklist with the objective of characterizing reading and writing activities that had been carried out by the subject as well as a semi-structured script comprised of open questions that have been divided into two large themes: experiential reading activities involving written language and the subject´s opinion regarding such given experiences. Three types of subjects have participated in the present research: an adult literate subject who uses written language as his/her personal and professional supporting tool; a literate subject who does not predominantly lean on written language for his/her personal nor professional support and, at last, an illiterate subject. The present information has been analyzed through nuclei of meaning, according to the proposal of Aguiar and Ozella. The analysis has revealed that senses attributed to written language contain naturalized elements such as the perception that written language has got superior qualities to oral language, the valuing of schooling literacy and the idea that a proper dominium of written language promotes ascendency, socially distinguishing people from one another. Elements such as teaching manners to present language at school, affection as a mediator of the relationship subject-object, presence of surrounding cultural elements, social inequalities and the characteristics of the capitalist mode of production have been discussed as determinants in the appropriation of written language by all subjects<br>A partir da categoria sentido, definida por Vigotski, a presente pesquisa buscou apreender os sentidos constituídos sobre a língua escrita para os sujeitos participantes e analisá-los ultrapassando a zona do funcional e da imediaticidade, caminhando assim, para zonas de sentido. Cientes de que só se apreende os sentidos situando-os em seu processo constitutivo, buscou-se uma forma de análise que articulou o particular ao todo, as significações às dimensões política e social da realidade material e ao conhecimento produzido na área, para alcançarmos os sentidos. Nesse processo, avaliou-se se os mesmos estão atuando em favor da manutenção da concepção dominante de letramento ou se são agentes de transformação social. O método utilizado foi o Materialismo Histórico Dialético e as informações foram produzidas por meio da dinâmica conversacional de González Rey. Os instrumentos utilizados foram um checklist com o objetivo de caracterizar as atividades de leitura e escrita realizadas pelo sujeito e um roteiro semiestruturado contendo questões abertas divididas em dois grandes temas: experiências vividas envolvendo a língua escrita e opiniões do sujeito a respeito da mesma. Participaram da pesquisa três sujeitos sendo: um sujeito adulto, alfabetizado que utiliza a língua escrita como suporte pessoal e profissional; uma sujeita adulta alfabetizada que não utiliza a língua escrita como suporte pessoal e profissional de maneira predominante e, por fim, uma sujeita não alfabetizada.

Their reflexes had beginning in Brazil starting from the second half of the century XX and it was resulted of the reduction in the fertility/mortality taxes, of the urbanization and of the increase of the life expectancy of the people. In the same way as there is the increase of the number of senior people, there is also a crescent disputes for new manners of living. Such fact lifts inherent questions of social stamp when living of the seniors in the Institutions of Long Permanence (ILPI), fear of this research, that he/she had as objective lifts the residents' of the Instituição Assistencial Nosso Lar, in Santo André-SP and to know the moments for two lived by the couples there residents, contributing to the implementation of public politics of home for senior. For so much he/she was employee the method of qualitative approach, using the interview semi-structured to pick four resident seniors' depositions in the researched Institution. We observed that the relationships to two in the Institution are permeated of prejudices so much on the part of the administration, that is not prepared to welcome seniors' couples, as on the part of the other interns, that you/they act with strangeness due to the rare moments of affectivity of the couples. It was also noticed a retraction on the part of the subjects interviewees in relation to the questions about the sexuality, once they became shy when verbalizing their moments of intimacy. We noticed that this is a theme that it still lacks studies more deepened and of operationalization of Public Politics of house for seniors so that these subjects have his/her respected citizenship when they choose an ILPI as home and place to live to two<br>O crescimento expressivo da população idosa é um fenômeno mundial. Seus reflexos tiveram início no Brasil a partir da segunda metade do século XX e foi resultado da redução nas taxas de fertilidade/mortalidade, da urbanização e do aumento da expectativa de vida das pessoas. Do mesmo modo como há o aumento do número de pessoas idosas, há também uma crescente demanda por novos modos de morar. Tal fato levanta questionamentos de cunho social inerentes ao morar dos idosos nas Instituições de Longa Permanência (ILPI), tema desta pesquisa, que teve como objetivo levantar o perfil dos residentes da Instituição Assistencial Nosso Lar, em Santo André SP e conhecer os momentos a dois vividos pelos casais ali residentes, contribuindo para a implementação de políticas públicas de moradia para idosos. Para tanto foi empregado o método de abordagem qualitativa, utilizando a entrevista semi-estruturada para colher depoimentos de quatro idosos residentes na Instituição pesquisada. Observamos que os relacionamentos a dois na Instituição são permeados de preconceitos tanto por parte da administração, que não está preparada para acolher casais de idosos, quanto por parte dos outros internos, que agem com estranhamento diante dos raros momentos de afetividade dos casais. Notou-se também uma retração por parte dos sujeitos entrevistados em relação aos questionamentos sobre a sexualidade, uma vez que se acanharam ao verbalizar seus momentos de intimidade. Percebemos que este é um tema que ainda carece de estudos mais aprofundados e de operacionalização de Políticas Públicas de habitação para idosos para que estes sujeitos tenham sua cidadania respeitada no momento em que escolherem uma ILPI como moradia e local para viver a dois

Abstract:
What are the elementary particles and how did the universe originate are the main driving forces in the high energy physics. In order to further demonstrate the standard model and discover new physics, several detectors are built for the high energy physics experiments. CMOS pixel sensors (CPS) can achieve an attractive tradeoff among many performance parameters, such as readout speed, granularity, material budget, power dissipation, radiation tolerance and integrating readout circuitry on the same substrate, compared with the hybrid pixel sensors and charge coupled devices. Thus, the CPS is a good candidate for tracking the charged particles in vertex detectors and beam telescopes.The power distribution becomes an important issue in the future detectors, since a considerable amount of sensors will be installed. Unfortunately, the independent powering has been proved to fail. In order to solve the power distribution challenges and to provide noiseless voltages, this thesis focuses on the design of a low noise, limited area, low power consumption and full on-chip power management in CPS chips. The CPS are firstly introduced drawing the design requirements of the power management. The power distribution dedicated to CPS chips is then proposed, in which the power management is utilized as the second power conversion stage. Two full on-chip regulators are proposed to generate the analog power supply voltage and the reference voltage required by correlated double sampling operation, respectively. Two prototypes have verified these regulators. They can meet the requirements of CPS. Moreover, the power management techniques and the radiation tolerance design are also presented in this thesis.

The first type was a commercially available sensor based on the principles of galvanic corrosion. The second type of sensors utilizes thin film electrodes of selected metals and the measurements are performed by LPR and Tafel slope methods. The performance and applicability of both types of these sensors are considered and explained.

Abstract:
Abstract A test spool containing two sets of sensors has been inserted in a high pressure environment of a natural gas production plant. The two flange-type sensors are configured so that moisture was more likely to accumulate at one than the other. Electrochemical noise (EN), linear polarization resistance (LPR), and harmonic distortion analysis (HDA) are used in combination to monitor the corrosion occurring in the plant. The 100-day corrosion data for the vertical and horizontal sensors show that corrosion rates were low and averaged ~0.0055 mm/yr. The measured B values were 0.035 V for the vertical sensor and 0.033V for the horizontal sensor, higher than the typical assume value of 0.026 V. The pitting factors were similar between the two sensors except that the vertical set had a prolonged higher pitting factor of 0.1 at the initiation of the test.

Abstract:
Abstract Corrosion rate measurement can reveal which areas of a structure need immediate maintenance and which ones will need maintenance later, as well as allow an optimal maintenance schedule to be developed. A new stamp-sized corrosion sensor allows measurement of corrosion rates based on well-established LPR (Linear Polarization Resistor) technology, which outputs an exact corrosion rate for the structure on which it is placed. The corrosion rate data can be monitored continuously or stored in a data collection node, to which 8 sensors are attached, and downloaded periodically. This sensor technology is being evaluated in the laboratory under various simulated corrosive field conditions. The sensor is being considered for corrosion monitoring applications on structures for mission critical equipment on military installations in severely corrosive environments. Results of laboratory experiments on the sensitivity of the sensor to the onset of corrosion on the substrate and projections for its applicability in the field will be discussed.

Full text
Abstract:
Abstract This paper describes a prototype dual mode corrosion monitor capable of measuring both instantaneous corrosion rate and the cumulative corrosion loss in atmospheric environments. The system consists of two components: a small flat sensor to be located in the area to be monitored and a battery powered meter unit to query the sensor. The sensor element is made of steel which is far more sensitive to atmospheric corrosion than most other metals; thus the sensor will react before significant damage has been done to other materials. The sensor itself is actually two discrete sensors on the same substrate and photo-etched from the same foil. Corrosion rate is measured using two-electrode Linear Polarization Resistance (LPR) while cumulative loss is measured by the Electrical Resistance (ER) method. The meter has been designed for operation by personnel with minimal corrosion knowledge. Its primary purpose is to alert an operator of the existence of corrosive conditions, thereby allowing remedial action to be taken before extensive corrosion damage has occurred.

Abstract:
Abstract Corrosion has many forms, occurring in a variety of plant and equipment, environments, materials and configurations. Matching sensor design and measurement technology is of paramount importance, yet something that may be overlooked outside of a laboratory environment. A range of sensor designs, including standard off-the-shelf linear polarization resistance (LPR) probes, have been validated over the past 22 years to measure such phenomena as pitting, crevice corrosion, microbial corrosion, stress corrosion cracking and localized corrosion in condensing, high hydrocarbon and high temperature environments. Over this period, on-line, real-time measurement technology has been refined to work with these sensors in providing the operator with simple process control-type data to assess both general and localized corrosion. This paper discusses a number of sensor designs and the available field-ready technology that have been used to measure general and localized corrosion in real life, in-plant and operational applications. Examples include radioactive waste storage, chemical process industry and power generation applications.

Full text
Abstract:
Abstract In order to develop a new corrosion sensor for detecting and monitoring the internal corrosion of water distribution pipeline, the selection of sensor elements and the correlation of sensor output to corrosion rate of steel pipe were evaluated by laboratory test methods in synthetic tap water. In this paper, two types of electrochemical probes were used: galvanic cells containing of pipeline steel-copper and pipeline steel-stainless steel (UNS S30400). The electrochemical behavior in synthetic tap water for the sensor elements was investigated by potentiodynamic test. Linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) measurements were conducted to obtain the corrosion rates of pipeline steel in synthetic tap water. The galvanic current density was measured by a zero resistance ammeter for Cu-CS and SS-CS probes. The correlation between the galvanic current of sensor and the corrosion rate of pipeline was evaluated in terms of the cumulative charge value. The results of the potentiodynamic test indicated that copper and pipeline steel exhibited active corrosion behavior, whereas stainless steel demonstrated spontaneous passivation. A good correlation was obtained by LPR and EIS measurements for corrosion rates of pipeline steel. In galvanic corrosion tests, the galvanic current of Cu-CS probe was higher than that of SS-CS probe. A comparison of the sensor output and pipeline corrosion rate revealed that Cu-CS probe showed a more reliable linear relationship than SS-CS probe. Consequently, it is proved that the copper was suitable for corrosion sensor element to detect the internal corrosion damage of water pipeline.

Full text
Abstract:
This paper investigates the feasibility of using non-cerebral, time-series data to detect epileptic seizures. Data were recorded from fifteen patients (7 male, 5 female, 3 not noted, mean age 36.17 yrs), five of whom had a total of seven seizures. Patients were monitored in an inpatient setting using standard video electroencephalography (vEEG), while also wearing sensors monitoring electrocardiography, electrodermal activity, electromyography, accelerometry, and audio signals (vocalizations). A systematic and detailed study was conducted to identify the sensors and the features derived from the non-cerebral sensors that contribute most significantly to separability of data acquired during seizures from non-seizure data. Post-processing of the data using linear discriminant analysis (LDA) shows that seizure data are strongly separable from non-seizure data based on features derived from the signals recorded. The mean area under the receiver operator characteristic (ROC) curve for each individual patient that experienced a seizure during data collection, calculated using LDA, was 0.9682. The features that contribute most significantly to seizure detection differ for each patient. The results show that a multimodal approach to seizure detection using the specified sensor suite is promising in detecting seizures with both sensitivity and specificity. Moreover, the study provides a means to quantify the contribution of each sensor and feature to separability. Development of a non-electroencephalography (EEG) based seizure detection device would give doctors a more accurate seizure count outside of the clinical setting, improving treatment and the quality of life of epilepsy patients.

Tire Experimental Characterization Using Contactless Measurement Methods. SAE International, 2021. http://dx.doi.org/10.4271/2021-01-1114.

Abstract:
In the frame of automotive Noise Vibration and Harshness (NVH) evaluation, inner cabin noise is among the most important indicators. The main noise contributors can be identified in engine, suspensions, tires, powertrain, brake system, etc. With the advent of E-vehicles and the consequent absence of the Internal Combustion Engine (ICE), tire/road noise has gained more importance, particularly at mid-speed driving and in the spectrum up to 300 Hz. At the state of the art, the identification and characterization of Noise and Vibration sources rely on pointwise sensors (microphones, accelerometers, strain gauges). Optical methods such as Digital Image Correlation (DIC) and Laser Doppler Vibrometer (LDV) have recently received special attention in the NVH field because they can be used to obtain full-field measurements. Moreover, these same techniques could also allow to characterize the tire behavior in operating conditions, which would be practically impossible to derive with standard techniques. In this paper we will demonstrate how non-contact full-field measurement techniques can be used to reliably and robustly characterize the tire behavior up to 300 Hz, focusing on static conditions. Experimental modal analysis will extract the modal characteristic of the tire in both free-free and statically preloaded boundary conditions, using both DIC and LDV. The extracted natural frequencies, damping ratios and full-field mode shapes will be used on one side to improve the accuracy of tire models (either by deriving FRF based models or updating FE ones) but also as a reference for future investigation on the tire behavior characterization in rotating conditions.
