Tensile Stress Analysis of Steering Knuckle of an Automobile under Static Load

摘要

Steering knuckle is one of the critical components of four wheel vehicle which links suspension, steering system, wheel hub and brakes to the vehicle chassis. During the motion of the vehicle the steering knuckle undergoes varying load under different conditions, but it doesn't affect the steering performance and other desired vehicle characteristics. The Steering Knuckle used for the experimentation is made of SG Cast Iron. For the experimental analysis Instron UTM of 100 KN load cell was used and the results validated in Finite Element Analysis (FEA). The results obtained from the virtual analysis and experimental analysis has been compared and validated for SG iron steering knuckle. Design solution was provided with the ANSYS Workbench 14.5 using Austempered Ductile Cast Iron Steering Knuckle.
