Abstract

Many of the chassis and suspension components are made from variety of sections. Most of them are the robust components assembled critically with other chassis part of the vehicle. The chassis components are used to carry the weight of the vehicle as well as some of them facilitates steering and absorb shocks due to road surface variations. Present competitive market of automotive industry demands for low cost and light weight components. Therefore more emphasis is towards design optimization for reducing weight while maintaining the structural stiffness unchanged. This paper more focuses on effect of geometrical parameters of different sections of chassis components on deflection characteristics by using a hybrid approach of statistical Taguchi method based on orthogonal array and Finite elements analysis (FEA). Using this method the most influencing parameters for deflection are identified through sensitivity analysis. The results obtained are used as a design guideline for generating optimized components with improved deflection performance.

Highlights

The present competitive market of automotive industry demands for low cost and light weight components
Many of the chassis and suspension components e.g. axle beams, body frames are made from variety of sections
Most of the researchers have been focused on improving material strength, replacement of alloy grades and geometry weight optimization, etc. These techniques will definitely reduce the weight of the component but adversely affects the deflection characteristics

Summary

Introduction

The present competitive market of automotive industry demands for low cost and light weight components. Any contribution to fuel economy reduction is important, but for many chassis and suspension parts, the reduction of unsprung weight is even more significant, offering improvement in handling performance and drive dynamics. The strength and stiffness of these components is an important aspect to avoid sudden failure. To solve these problems, most of the researchers have been focused on improving material strength, replacement of alloy grades and geometry weight optimization, etc. Most of the researchers have been focused on improving material strength, replacement of alloy grades and geometry weight optimization, etc These techniques will definitely reduce the weight of the component but adversely affects the deflection characteristics. As most of the chassis components are in supported and cantilever loading conditions, instead of taking entire component; the study on different geometrical sections is an effective and quick way of optimization
