Rack and Pinion Steering System Design for a Passenger Car

Abstract

The steering system plays a crucial role in the stability of the automobile, especially in the safety of the passengers and pedestrians. The aim of this work is to design a rack and pinion steering system that could equip a passenger car. In this process, many parameters are considered for the correct and effective directional response behavior of the vehicle. 2D models were sketched to validate the kinematic algorithm calculus used to optimize and refine the dimensions of the components of the steering system. After a satisfactory Ackermann percentage was achieved, steering system is designed and analysed in one of the most used CAD and CAE software in automotive, CATIA.
