Abstract: Ball joint assembly has been widely used in the important parts of cars, in order to ensure the mechanical safety performance of ball joint assembly structure, according to the bench test items, the finite element simulation analysis method based on tribology mechanism is adopted to calculate the axial crushing strength, assembly static strength and fatigue life. Basically, a simulation analysis method be summarized which to verify the mechanical safety performance of ball joint assembly structure.

Key words: Ball joint assembly, Crushing strength, Tribology, Fatigue life
