Static Analysis of Automotive Steering Knuckle

Steering knuckle is one of the critical components for a four wheel vehicle which links suspension, steering system, wheel hub and brake to the chassis. While undergoing varying loads subjected to different conditions, it doesn’t affect vehicle steering performance and other desired vehicle characteristics. The static strength test for steering knuckle is necessary to validate the component according to the application. Here, the steering arm static analysis of steering knuckle was done by using finite element analysis (FEA software) and experimental testing by using hydraulic actuators and fixtures. The result from the virtual Analysis and Experimental analysis has been compared and validated for the SG Iron Steering knuckle.
