Combining the equivalent stiffness model for rear axle,the deformation coupling characteristics of the unsymmetrical rubber bush,and the models for shock absorber and coil spring,an equivalent dynamics model for the torsion bar rear suspension is set up.

• 结合轿车扭杆式后桥的等效刚度力学模型、后悬架非对称橡胶衬套的变形耦合特性以及减振器、螺旋弹簧的力学模型,建立轿车扭杆式半独立后悬架的等效动力学模型。
