The purpose of this study is to realize a vehicle dynamic analysis considering the influence of the compliance steer by using a simplified calculation method. In this method, the compliance steer was calculated by using stiffness matrices and the constraint forces acting on the suspension arms instead of considering the deformation of each rubber bush. The characteristics of the rubber bushes included in a suspension arm were merged in one stiffness matrix. In the multibody vehicle dynamic analysis, the obtained compliance steer of the wheel was considered in the tire force calculation. In order to confirm the validity of the proposed method, the dynamic analysis of the multibody vehicle model with rubber bushes defined as the force elements was conducted. The result of the vehicle dynamic analysis with rubber bushes defined as the force elements and the results of the vehicle dynamic analysis with the proposed method were compared.
