STRUCTURAL ANALYSIS OF TRUCK CHASSIS USING FINITE ELEMENT METHOD

This paper aims to redesign a modified chassis for truck by keeping the material and dimension similar and using ‘I’ cross section area instead of ‘C’ resulted in more safer stresses than ‘C’ and the material used is mild steel. 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. Also, it should be rigid enough to withstand the shock, twist, vibration and other stresses. Along with strength, an important consideration in chassis design is to have adequate bending stiffness for better handling characteristics. So, maximum stress, maximum equilateral stress and deflection are important criteria for the design of the chassis. FEA is done on the modeled chassis using the ANSYS Workbench11; the FEA is carryout for static, dynamic and shape optimization.
