Analysis and Design Modification of a Chassis

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 and torsional stiffness for better handling characteristics. So, strength and stiffness are two important criteria for the design of the chassis. This report is the work performed towards the optimization of the automotive chassis with constraints of stiffness and strength. Structural systems like the chassis can be easily analyzed using the finite element techniques. An optimization algorithm will then require several structural analysis to reach the optimum point. So a proper finite element model of the chassis is to be developed. The chassis is modeled in PRO-E. FEA is done on the modeled chassis using the PRO/MECHANICA. The results of the optimization are presented in this Book.
