Strength and fatigue life analysis of automobile steering knuckle
Taking an automobile steering knuckle as the object of study,the working load was determined through three typical working conditions:uneven road,emergency braking,and side slip.Using finite element analysis method for static strength calculation,the results showed that the maximum stress of the steering knuckle was 100.7 MPa,which was less than the material yield limit of 207 MPa,meeting the static strength requirements.Using simplified load spectrum for fatigue analysis of the steering knuckle,the results showed that the fatigue life of the steering knuckle under emergency braking conditions was 2.3×106 times,meeting design requirements.Applying finite element analysis method to analyze automotive steering knuckles in the early stages of development is beneficial for shortening the part design cycle and reducing costs.
