Steering knuckle is a prominent component of an automobile steering system. It is subjected cyclic loads from the suspension system during its service life. The Spheroid Graphite (SG) iron is the most commonly used material for manufacturing the steering knuckle. Fatigue behaviour is therefore a key consideration in its design and performance evaluation. Geometric modelling and stress analysis of such steering knuckle using finite element analysis software is carried out. Then the fatigue life of steering knuckle made from SG iron has been evaluated under the different load conditions and the results have been compared.

Abstract


Steering knuckle is a prominent component of an automobile steering system. It is subjected cyclic loads from the suspension system during its service life. The Spheroid Graphite (SG) iron is the most commonly used material for manufacturing the steering knuckle. Fatigue behaviour is therefore a key consideration in its design and performance evaluation. Geometric modelling and stress analysis of such steering knuckle using finite element analysis software is carried out. Then the fatigue life of steering knuckle made from SG iron has been evaluated under the different load conditions and the results have been compared.
