STRESS AND WEIGHT ANALYSIS OF LADDER FRAME OF LIGHT DUTY TRUCK

Abstract

Automobile chassis can be considered as the backbone of any vehicle. Chassis tasked is to hold all the essential components of the vehicle. Chassis should bear less stress and also light in weight to reduce dead weight on the vehicles. This dissertation is aimed to produce result to rectify problem associated with structures of a commercial vehicle such as strength and deflection properties along with stress.This can be achieved by static analysis of chassis of different thickness and height using Finite Element Method (FEM).The work shows the possibility of reducing stress developed in the chassis frame with in desired load carrying capacity and increase load carrying capacity by decreasing maximum stress and deflection in the critical area of chassis frame design in early design stages. This although will not give exact solution but can give a near optimal initial design of chassis frame, thus reducing the effort for optimization during the detailed design phase. This study aimed to static load analysis of the chassis of “TATA SUPER ACE” by using ANSYS 16.0 workbench for different thickness and height of chassis frame.
