Finite Element Simulation of Knuckle and Strut Arm Column Assembly for Automotive Steering System
Main Article Content
Abstract
Steering knuckle is one of the important parts in the vehicle steering system. Under certain operating conditions, the knuckles reliability threatens the safety of people and vehicles directly. At emergency braking condition, mostly strut arm and steering arm have maximum deflection in steering knuckle when it is subjected to various load cases. In this work, finite element analysis of the spheroid graphite (SG) iron strut arm of steering knuckle with strut mount assembly was carried out to predict its deflection under static load. The analysis result was compared with that of the experimental results to put forward directions to optimize the shape and material selection.
