Design & Analysis of Ladder Frame I Section Chassis

Abstract

This Chassis frame is the basic frame work of an automobile. It supports all the parts of an automobile which are attached to it. With the increase in the weight of the chassis, load on the engine increases thus performance of vehicle decreases. Thus, to improve the efficiency of vehicle the reduction of weight of the chassis is needed. In this work, we have considered ASTM A710C Steel as the material for the chassis. This material properties are applied on a ladder chassis and is analyzed under maximum load conditions. The ladder chassis is designed with I shaped cross section for long members and C shaped cross section for cross members and further material is removed from the cross members, so as to reduce the weight. Chassis is modeled in SOLID WORKS with appropriate dimensions. Static Structural analysis is done in ANSYS Workbench. Results are compared with the existing chassis model values.
