Abstract

Independent steering system is the most important system in any vehicle. This lets the driver get full control over the car maneuver. The cradle or subframe is an important component of the vehicle with various functions. It is used to improve the ride comfort and handling capability. The aim of using an automotive subframe is to spread large local loads across wider area of the body structure and making the vibration and harshness separated from the body structures. This paper is aim to find the most suitable thickness for the cradle in order to withstand the stresses. This paper also described the type of steering system such as steer-by-wire, four wheel steering, rack and pinion and the recirculating ball steering. Material used for manufacture this cradle are aluminium. The analysis of the cradle is by using Finite Element analysis (FEA) of CATIA software. The analysis are done using thickness of 6mm, 8mm and 10mm. The amount of force for rear cradle is 883N and 442N for the front cradle. From the analysis it is concluded that 6mm thickness is the most suitable thickness for the cradle and the minimum thickness that can be used to manufacture the cradle is 2mm.
