摘　　要：详细推导了抗侧滚扭杆装置对车体的作用机理,采用一个集中点力元代替整套扭杆装置建模。仿真计算结果表明,误差在允许的范围内,简化建模完全可以取代完整建模,不会对车辆动力学计算的各项指标造成影响。The functional mechanism of the anti-rolling torsion bar device on carbodies is deduced in detail. A concentrated point is used to replace the full set of torsion bar device in modeling. It is obtained from the simulation calculation results that the tolerance is within the permissible range, the simplified model can replace the complete model, and will not have any effect on the various indexes in the dynamics calculation of vehicles.
