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.

The thermal characteristics of the motorized spindle determines maching qualities and cutting capabilities, and is one of the important factors influencing the precision of the high speed NC machine tool. To improve the performance of the high speed machine tool, it is important to study the thermal characteristics of the motorized spindle. It had been studied in two ways: one is finite element analysis by Ansys software, in which the finite element analysis model was built. According to the actual working condition, the heat source and the heat transfer coefficient of every part are calculated. On this basis, the temperature field and temperature rises were gotten in Ansys software. The other way is temperature rises experiment on the motorized spindle test platform. The result was shown in the form of curve. These two ways shown the same result: the highest temperature rise appears in the area of electromotor, then followed by the rolling bearing .The result provides the necessary theory basis for optimizing the structure of the motorized spindle and establishes a basis for the research and application about the high speed spindle.

Crash analysis of non-air-conditioned sleeper bus has been carried in present work. Using relevant automotive industry standards (052 and 119) bus dimensions are considered for design. Surface modeling technique is used to prepare computer aided model. Further the bus design is freeze using finite element analysis for different crash conditions as front impact, side impact and rear impact. Crash analysis of the proposed bus design is carried using Ansys Workbench. Using the outcomes from finite element analysis as stresses, deflections, internal and kinetic energies during various crash conditions are estimated. Mesh generator is used to mesh the complex bus model. The stress and deflection magnitudes of proposed bus model are in good agreement with the experimental results available in literature. Design improvements are made using the finite element analysis outcomes, observing the deformation patterns additional pillar members of suitable length are added to increase the dynamic crush and further enhance occupant safety during collisions.

Abstract: The car's chassis is also called a structure that locates and mounts all the vehicle's components. It also creates a secure environment for the occupants. The chassis will provide torsional and flexural rigidity to the vehicle that makes the chassis one of the most crucial elements of the vehicle. Therefore, the front impact, rear impact, side impact, front torsional, rear torsional, vertical bending, lateral bending analyses were performed. The contribution of chassis is not limited to supporting the vehicle’s component, but it extends to providing better performance and aesthetics. Therefore, the design of the car chassis must be done accordingly. The current paper deals with the study of the design and analysis of the race car. The deformation, stress, and Factor of safety were considered as the evaluation parameters which were obtained by Finite Element Analysis (FEA) in Ansys software. To design the chassis, the SolidWorks software was utilized. Keywords: Car Chassis, Design, FEA, Material Comparison.

Rigidity Analysis

When the FA pin-cycloid drive is used in high precision control drive system, especially in the robot drive, there are strict requirements to torsional rigidity .Usually in rated torque, the elastic lost motion produced by the torsional elastic deformation must meet certain precision. This paper analyzes all kinds of elastic factors which affect the rigidity, establishes mathematical model of the machine rigidity and calculates the rigidity for the FA pin-cycloidal drive. Meanwhile ANSYS is applied to build finite element analysis model, and the finite element contact analysis results coincide with the rigidity analysis theory, which confirms the correctness of the machine rigid mathematical model.
