Abstract:

The chassis is the backbone of all automobiles. In passenger cars and buses, the chassis forms the basic shape of the vehicles and ensures the safety of passengers as well as transported goods. Most chassis have the frame structure and is manufactured using stamping and cold rolled technology to enhance the required rigidity. One of the most important criteria that chassis manufacturers consider during the design process is structural integrity: preventing failure while optimizing the use of materials. Traditional design methods requiring hand-calculations as well as experiments are less desirable because of the rising cost and time. Nowadays, with the development of numerical methods, computer capabilities and computer-aided engineering (CAE) overall, the design process has become much more efficient. This paper presents a procedure to simulate the complex dynamics of a 29-seat bus chassis using finite elements analysis in Ansys software. The results of this simulation are then used to verify the structural integrity of the chassis and support design optimizations.

Abstract:

The structure of dynamic compaction machine’s chassis is box girder which is welded by steel plate. The strength and stiffness of the chassis directly affect the performance of the machine and the safety of dynamic compaction. According to the mechanical characteristics of a 600t•m dynamic compaction machine, the author analyzed the stress distribution and deformation of the chassis under three kinds of working conditions by finite element method. The results show that the finite element method can effectively reflect the overall state of stress and the characteristics of local stress of the chassis. The structure of chassis has sufficient strength and stiffness. The thickness of some parts of the steel plate can be properly reduced. These results provide basis for the further optimal design of the chassis.

Abstract:

By modeling of sugarcane leaf cutting off returning to field machinery chassis and loading, this paper simplifies reasonably several different conditions of the chassis to the two forms. The finite element is used for the solution of the problem by using ANSYS software, solving the node stress contour of the chassis. Compared the maximum stress in the most dangerous working conditions to the allowable stress of the material, the result verifies the chassis strength to meet the design requirements. According to the vibration of the chassis at work, analyzing the first sixth modal of the chassis, and comparing with excitation frequency shows that the design of the chassis avoids the excitation frequency, which does not cause resonance at work. The results show that the chassis meets the design requirements.

Abstract:

The increasing demand for energy efficient electric cars, in the automotive sector, entails the need for improvement of their structures, especially the chassis, because of its multifaceted role on the vehicle dynamic behaviour. The major criteria for the development of electric car chassis are the stiffness and strength enhancement subject to mass reduction as well as cost and time elimination. Towards this direction, this work indicates an integrated methodology of developing an electric car chassis considering the modeling and simulation concurrently. The chassis has been designed in compliance with the regulations of Shell Eco Marathon competition. This methodology is implemented both by the use of our chassis load calculator (CLC) model, which automatically calculates the total loads applied on the vehicle’s chassis and by the determination of a worst case stress scenario. Under this extreme stress scenario, the model’s output was evaluated for the chassis design and the FEA method was performed by the pre-processor ANSA and the solver Ansys. This method could be characterized as an accurate ultrafast and cost-efficient method.

Abstract:

Recently the truck industry has experienced a large push to overcome the increasing demands of higher performance, lower weight, and longer life of components, all this at a reasonable cost and in a short period of time. Conducting experimental test in the early stage of design is time consuming and expensive. In order to reduce the cost, it is important to conduct simulation using numerical methods by software to find the optimum design. In practice, many of the finite element objects are very large so it makes a difficulty in meshing and also in analysis of the model. It very takes time and need a lot of memory of computer. Submodeling technique offer the solution about that problem. This paper presents the submodeling technique that applied on the corroded truck chassis.

Abstract: Automotive chassis is an important part of an automobile. The chassis serves as a frame work for supporting the body and different parts of the automobile. The chassis frame has to withstand the stresses developed within a limit. Along with strength, an important consideration in chassis design is to have adequate bending stiffness for better handling characteristics. So, strength and stiffness are two important criteria for the design of the chassis.

Abstract:

The current work contains the design and optimisation of a spaceframe chassis for a track racing one manned formula car able to participate in the Formula Society of Automotive Engineers (Formula SAE) 2017/2018. Materials, profile cross section types were selected by considering the theories of elastic failure. The structural strength of the chassis was determined by Finite Element Analysis using ABAQUS software by determining the stress distribution during static and dynamic loading in addition to exposing the modal frequencies. Beam elements were used in the finite element model as it provides accurate modelling of small deflection bending responses. A simple baseline chassis design was developed that adheres to the Formula SAE 2017/2018 rules. Optimisations were made in terms of the configuration and material utilisation of the chassis members were done to prevent yielding during the static loading of car components and dynamic loading during acceleration and cornering. Furthermore, the same method of optimisation was used in prevention of the coincidence of natural frequency with the frequency of the engine.

Abstract:

Formula Student Racing competitions are held at various Formula SAE circuits globally. Chassis serves as an important component in the race car design. Thus a solicitous analysis is expected out of the formula car. It is also noted that the weight of the car is inversely proportional to the performance of the car hence need for optimization. A high speed protection system plays a major role in the race car design such as front impact, rear impact, side impact and roll over analysis. Also, there exists a problem of the torsional rigidity as far the dynamics is considered. This paper aims at the design aspects and the analysis insights of the race car. The car is modelled according to the 95th percentile male that can fit inside the cockpit of the chassis. As the car travel at the high speed, the protection has been designed to the car in such a way that stresses are minimum and the performance is maximum. Finite element methods are used for the analysis and the design of experiments is created for the optimization of the chassis. To avoid any possibilities of failure of the structure and thus to provide enough supporting member to make the region stronger in term of deformation . Finite element analysis enables to predict the region that tends to fail due to loading, the distribution of stress and strain on the chassis, both component as well as the material costing. The main objective is to study the effect of the validations of the FEM result are given using the different profiles like RECTANGLE, CIRCULAR, AND I SHAPE convergence methods for car body and the equipment.

Abstract:

Structural failures in a Chinese sport utility vehicle (SUV) Land-wind X6 chassis were reported in recent years, thus, it is meaningful to conduct trouble-shooting and effective optimization to improve the chassis. Stress relaxation of the Land-wind X6 chassis using a novel dynamic force counteracting approach was carried out in this study. Finite Element Analysis (FEA) model of the chassis was firstly established and theoretical modal analysis was performed using the FEA model, experimental modal analysis was followed to validate the theoretical modal analysis and the FEA model. Further static and local stress analyses demonstrate that irrational designs between the longitudinal beams and the suspension components lead to inadequate stiffness and excessive stress concentrations which would cause fatigue and structural failure when the SUV chassis is subject to complex and severe excitations. A novel dynamic forces counteracting approach was introduced to optimize the chassis structure, FEA results show that excessive stress concentrations were obviously eliminated and the chassis stiffness, especially the torsional stiffness was greatly improved after optimization, followed industrial implementation also verifies that the FEA-based study and product optimization performed in this work are successful and significant.

Abstract:

Due to the current unstable travel performance and poor driving maneuverability of rice combine harvester crawler chassis with high load in the rice field, the driver’s standard sitting posture model was developed by analyzing the handling of the crawler chassis driving control panel. Based on this model, the joystick length and cab manipulation space layout were designed. The Finite Element Software was used to develop the loading and restraining model of the chassis frame, and then the structural characteristics and bearing capacity of the crawler chassis were analyzed. The high-bearing running stability and the rationality of operating force of the joystick of rice combine harvester crawler chassis designed in this paper through experiments were verified by experiments. The results showed that when the crawler chassis of rice combine harvester bears a load of 3.5 t, the driving speed is relatively stable in the three speed ranges of 1 m/s, 1.5 m/s, and 2 m/s, and the maximum variance of driving speed variation is 5.022 × 10−4. The actual average operating force of each operating lever on the crawler chassis ranges from 30.36 to 42.71 N, and the operating force of each operating lever is suitable for 95% of Chinese adult male operators. The research results provide a good method and reference for the future development of the crawler chassis structure of rice combine harvester.

Abstract:

In this research, stress measurement tests and advanced application algorithms based on computer-aided design and engineering (CAD and CAE) were developed and tested. The algorithm was put implemented through a case study on the strength-based structural design and fatigue analysis of a chassis. This algorithm consists of numerical and experimental methods and additionally includes material tests, three-dimensional CAD, a finite element method (FEM)-based analysis procedures, a structural optimization strategy, prototype production, stress tests, a fatigue analysis, and design verification procedures. In the optimization study targeting the optimum chassis weight/strength ratio, two chassis prototypes, with 8 mm and a 5 mm wall thicknesses, were manufactured to verify the structural analysis and experimental tests. As a result of the FEA analyses, for 20 kN, which is the target load value of the chassis, for chassis thicknesses t = 5 mm and t = 8 mm, the maximum tensile strength was obtained as 93 MPa and 83 MPa, respectively. Thus, the material gain of 35.85 kg mass was achieved, and chassis utilization efficiency was increased. This research provides a useful methodology for experimental and advanced CAE techniques, especially for further research on complex stress and deformation analysis of chassis that are desired to be of optimum weight/strength ratio.

Abstract:

The objective of this research is to design a spaceframe chassis for light weight automobiles possessing unladen weight of ≤ 550Kg to replace the conventional monocoque type chassis frame. The maximum stress and maximum deflection that the chassis can resist without fracturing are important criteria. In this thesis, the existing monocoque chassis was considered and analyzed under static loading, frontal impact, side impact, rear impact, front rollover and side rollover loading conditions by using Finite Element Analysis method. Then, taking the test results as a reference, a spaceframe chassis was designed for the same size vehicle. The critical evaluation standard points stated in the Federal Motor Vehicle Safety Standard (FMVSS), U.S.A standard, were used as guideline to see the performance of the existing and the new chassis frames. The test results show that a space frame chassis has better stress resisting capacity and reliability than the conventional monocoque chassis frame under all impacts.

Abstract:

As an effective way of passive damping, isolation technology has been widely used in all types of building structures. Currently, for its theoretical analysis, it usually follows the rigid foundation assumption and ignores soil-structure interaction, which results in calculation results distortion in conducting seismic response analysis. In this paper, three-dimensional finite element method is used to establish finite element analysis model of large chassis single-tower base isolation structure which considers and do not consider soil-structure interaction. The calculation results show that: after considering soil-structure interaction, the dynamic characteristics of the isolation structure, and seismic response are subject to varying degrees of impact.

Abstract:

Nowadays, the hull suspension systems that use torsion shafts as elastic suspension elements are fitted to the majority of modern tracked vehicles. The main type of failure in such systems is the fracture of the torsion shafts due to the formation of fatigue cracks, which leads to failure of the suspension assemblies. This work presents an analysis of fracture toughness of torsion shafts of a standard tracked chassis used to develop a family of multipurpose transport vehicles GT-TM, GT-TMS, etc. The analysis is carried out under an operating load level for a crack located on the cylindrical part of the torsion shaft, the plane of which is at an angle to the torsion shaft axis and coincides with the position of the main areas of the stress state. The calculation of fracture toughness is based on Irwin fracture criterion. The calculations of the maximum stress intensity factor along the crack front are performed using the finite element method in the ANSYS software package. The results of the analysis of fracture toughness are presented in the form of dependences of the critical depth of the crack on the ratio of the fracture half-length to its depth. The data obtained can be used to determine the residual life of torsion shafts of the tracked vehicles based on the chassis under consideration. Keywords: suspension system, fracture toughness of torsion shafts, edge crack, stress intensity factor, finite element method, Irwin fracture criterion.

Abstract:

Onion farming is more commonly practiced for an irrigated crop, resulting in a high yield with large sized bulbs. Manual harvesting of an onion being meticulous requires a large amount of manpower as well as time. Thus, we have constructed and evaluated a self-propelled onion harvester which will have good performance in terms of productivity, fuel economy, less damage to crop and operator comfort. This paper is intended to discuss the results of the design and analysis of the chassis under the guidelines of the SAE TIFAN rulebook [1]. The chassis is designed using tool CATIA V5 followed by Finite element analysis (FEA) using ANSYS and the consequent results have been plotted and comparative results of old and modified chassis has proposed. During chassis designing and analysis, several factors are taken into account like material selection, strength, durability, boundary conditions, force distribution, induced stresses, optimum factor of safety, ergonomics and aesthetics. All the decisions for design are based on all pros and cons from testing and results of previous competitions.

Abstract:

Combining substructure and power flow theory, in this paper an external program is written to control MSC. Nastran solution process and the substructure frequency response are also formulated accordingly. Based on a simple vehicle model, characteristics of vibration, noise, and power flow are studied, respectively. After being compared with the result of conventional FEM (finite element method), the new method is confirmed to be feasible. When it comes to a vehicle with the problem of low-frequency noise, finite element models of substructures for vehicle body and chassis are established, respectively. In addition, substructure power flow method is also employed to examine the transfer characteristics of multidimensional vibration energy for the whole vehicle system. By virtue of the adjustment stiffness of drive shaft support and bushes at rear suspension lower arm, the vehicle interior noise is decreased by about 3 dB when the engine speed is near 1050 rpm and 1650 rpm in experiment. At the same time, this method can increase the computation efficiency by 78%, 38%, and 98% when it comes to the optimization of chassis structure, body structure, and vibration isolation components, respectively.

Abstract: A bike frame is also a non-standard structural component of a motorcycle linking various components of the vehicle systems and providing the vehicle rigidity and strength while running on various road conditions. This study is geared toward designing the frame of a two-wheeler, two-seater motorcycle for an electrical mobility purpose, while considering strength, safety and optimum performance of the vehicle. The said study has been allotted with a two-step approach. the first step includes modelling of the frame as per structural and ergonomic considerations, the design constraints governed by the front and rear suspension, steering and transmission systems and assemblies further because the determination of loads functioning on the frame. The second step is that the strain analysis using finite element analysis software and magnificence modifications for weight reduction without affecting structural strength. The main aim was to cut back the burden, centralize the load and lower the burden of the frame. Thus, the metal tubes were divided into primary, secondary and tertiary members supported the tube diameters and thicknesses so on reduce the final weight of the frame without affecting its strength. The centre of gravity of the frame is below the rider way thus ensuring an occasional and centralized frame weight. The trusses not only provide strength and rigidity but also safety of the actuation and essential vehicle components against impacts. The chassis is additionally a skeleton upon which parts like battery and motor are mounted. The two-wheeler chassis consists of a frame, suspension, wheels and brakes. The chassis is what truly sets the sort of the twowheeler. Commonly used material for two- wheeler chassis is steel which is heavy in weight or more accurately in density. There are various alternate materials like aluminium alloys, titanium, carbon fibre, magnesium, etc. which are lesser in weight and provide high strength and thus are often used for chassis.

Abstract:

"The two most significant engineering steps required in developing a good quality vehicle is crash and structural analysis in the field of automobile design. Simulating the crashworthiness of the vehicle is a significant step to design automobiles of the present age and automotive industry has probably the widest application of such simulations. Crash simulation is a virtual representation of a destructive crash test of a vehicle and its components using computer-aided analysis software to examine the level of safety of the vehicle and its occupants by analysing the level and nature of impact stresses occurring in the component and the magnitude and nature of the deformation happening in the cosmponent during a crash situation. In the current study, a road cum rail vehicle is designed. The main purpose of the vehicle is to clean the rail track. Since the vehicle will be used on the live rail track so it is very important to know the dynamic behaviour of the vehicle during crash or impact. The dynamic behaviour of complete vehicle chassis with four rail wheel and for rubber wheel in contact with rails and moving at 60 km/hr is simulated under frontal crash. Further, 10g frontal impact and the 5g rear impact are also applied on the developed vehicle chassis at rest to investigate its dynamic behaviour"
