Abstract:

This dissertation describes a numerical modelling strategy for characterising the windage of a spiral bevel gear rotating within a static shroud. The techniques employed include the use of a parametric solid model, and flow field modelling using computational fluid dynamics (CFD) software. A number of hypothetical physical alterations are made to a control system consisting of a gear and a shroud, based on those found in a Rolls-Royce aero engine. Windage is a parasitic power loss that occurs when a gear does work on air and oil within a gas turbine internal gearbox. It leads to degradation of

Abstract:

A study was performed to investigate and optimize the application of perforated fairings for landing gear noise control. The sparse knowledge about this new subject has necessitated a more fundamental study involving a basic fairing-strut configuration, followed by wind tunnel tests on a simplified landing gear configuration incorporating perforated fairings. For the basic configuration, various exchangeable perforated half-cylindrical shells shrouding a circular cylinder were the subject of aerodynamic and acoustic tests. A qualitative and quantitative description has been given of the influe

Abstract:

Noise generated by aircraft landing gears is a major contributor to the overall airframe noise of a commercial aircraft during landing approach. Because of the complex geometry of landing gears, the prediction of landing gear noise has been very difficult and currently relies on empirical tools, which have limited reliability and flexibility on the applications of unconventional gear architectures. The aim of this research is to develop an efficient and accurate numerical method to investigate the generation and far field radiation of the landing gear noise. In this thesis a hybrid approach is

Abstract:

Transmission error is a measure of the positioning accuracy of a gear system. This has been widely documented in gearing for many years as the source of problems in noise and vibration. It is a result of errors in the contact conditions which affect the driven gear with respect to the rotation of the driver gear. This research aims to present a better understanding of the basic kinematics of worm gear systems by identifying the significant influences which determine the contact conditions. A literature review of existing theory is described which determines the major areas considered in worm g

Abstract:

It is often impractical to measure vibrations directly at /or close to their sources when condition monitoring gearbox systems. It is common to measure the vibration distant from the source due to limited access to the component which is to be monitored. In addition, operating the gearbox under different loads and speeds also produces vibration signals within different components. Vibration measured in this way may be significantly distorted by the effect of signal transmission paths and interference from other sources. Therefore, suppression of distortions is a key issue for remote measuremen

The presented algorithm is an art of adaptive modeling of the torque balance over a range of steady operation in fault free behavior.

Abstract:

The rules and specifications of competition Formula Student are the main guidelines at frame design of students' formula. This diploma work discusses frame safety and structural requirements and also requirements on mounting of engine, single axles, rear-axle differential, engine intake and exhaust system, fuel tank, control elements, and so on. In the final parts of this diploma work analysis of maximum state of stress in material of on-load frame is made and total frame torsional rigidity is calculated. Total frame torsional rigidity is compared with those of Formula Ford and with other vari

Abstract:

This thesis develops dynamic models for the two-mode FWD EVT, develops a control system based on those models that is capable of meeting driver torque demands and performing synchronous mode shifts between different EVT modes while also accommodating preferred engine operating points. The two-input two-output transmission controller proposed herein incorporates motor-generator dynamics, is based on a general state-space integral control structure, and has feedback gains determined using linear quadratic regulator (LQR) optimization. Dynamic modeling of the vehicle is categorized as dynamic mo

Abstract:

Les véhicules de demain, (2020), devront diminuer leurs émissions globales de CO2 de 30% selon les directives européennes. Une solution qui apparait aujourd’hui comme inévitable est la substitution des métaux présents dans les châssis de véhicules par des matériaux composites plus légers et tout aussi performants. Pour généraliser cette approche à tout le secteur automobile, un temps court de fabrication des pièces est exigé pour satisfaire les cadences de production allant jusqu’à 1000 véhicules par jour. La production automatisée et robotisée de ces matériaux, basée sur la technologie de pho

Abstract:

Bien qu’ils soient largement utilisés dans le domaine, les mesures vibratoires classiques présentent plusieurs limites. A la base, l’analyse vibratoire ne peut identifier qu’environ 60% des défauts qui peuvent survenir dans les machines. Cependant, les principaux inconvénients des mesures de la vibration sont l’accès difficile au système de transmission afin d’y placer le capteur ainsi que le coût conséquent de la mise en œuvre. Ceci résulte en des problèmes de sensibilité relatifs à la position de l’installation et ceux de difficulté pour distinguer la source de vibration à cause de la divers

Abstract:

The conventional slider crank engine has dominated the industry with very few alternative configurations having commercial success. In aircraft applications where engine balancing is critical to reduce vibrations, boxer engines have been developed to reduce this issue. The rising cost of fuel and awareness of pollutant emissions has led to an increased interest in alternative designs where both opposed piston and geared hypocycloid engines present some advantages over the conventional slider crank engine. In this study, a comparison between an opposed piston slider crank and geared hypocycloi

Abstract:

The ability to communicate over a low bit-rate transmission channel has become the order of the day. In the past, transmitted data over a low bit-rate transmission channel, such as a wireless link, has typically been reserved for speech and data. However, there is currently a great deal of interest being shown in the ability to transmit streaming video over such a link. These transmission channels are generally bandwidth limited hence bit-rates need to be low. Video on the other hand requires large amounts of bandwidth for real-time streaming applications. Existing Video Compression standards

To minimize the size of the device, a systematic scheme is proposed. From the outer annular-arranged transverse-flux magnetic gears set and the permanent magnet synchronous motor, the input electric power can be converted directly to supply larger output mechanical torque without additional mechanical devices. The preliminary parameters and electromagnetic properties of the device can be roughly estimated by the numerical models based on the

Abstract:

碩士<br>國立成功大學<br>機械工程學系<br>87<br>This work presents an innovative concept, namely MOGEAR, by combining the design of (DC) motors and (gear) reducers. Existing DC motors and gear reducers are studied, and their characteristics are concluded. According to the driving principle of the DC motors, we redefine the relation between the stator and the rotor, i.e., the stator is not necessary to be fixed and the rotor is not necessary to be the output. As long as the stator keeps the same relative velocity with the rotor, the motor can still function. This concept is totally new in the des
