Abstract: When Adams is used to solve the swing angle of the ball pin of the stabilizer bar of McPherson type front suspension, ball joints modeling for both upper and lower stabilizer bar link end cannot meet the requirements of degrees of freedom. Conventional modeling replaces one of the ball joints with a hooke or a constant velocity pair. But they cannot be deflected around the axis of the stabilizer bar link. The movement of which is seriously inconsistent with the actual situation. Therefore, this modeling method cannot guide the design of swing angle of the ball pin. The bushing has six degrees of freedom and can be equivalent to the properties of the ball joint by setting the stiffness in each direction. Hence, this paper proposes a modeling method of using bushing instead of ball joint at both stabilizer bar link ends. At the same time, the contact conditions of the ball pin and cup are established to validate the situation that the ball pin is limited after being placed at the maximum angle in the actual use.
