차량동역학 해석을 위한 효율적인 현가장치 모델링 기법

This paper presents an efficient modeling method of suspensions for vehicle dynamic simulations. The suspension links are modeled as composite joints. The motion of wheel is defined as relative one degree of freedom motion with respect to car body. The unique relative kinematics and kinematic constraint formulation between car body and wheel enables to derive equations of motion in terms of wheel vertical motion. By using velocity transformation method. The system equations of motion is systematically derived without kinematic constraints. A simple simulation example demonstrate the effectiveness of proposed method.
