摘要
利用某轻型客车的CATIA三维设计数模进行运动仿真,得到悬架线刚度,并与试验结果进行对比,验证了运动仿真结果的正确性。在ADAMS/Car中建立了双横臂扭杆弹簧独立悬架动力学模型,进行动力学仿真计算得到悬架的线刚度,并通过与CATIA中运动仿真计算所得的线刚度对比分析,验证了动力学模型的正确性。该方法同样适用于其它类型独立悬架的动力学模型验证。
The liner stiffness of a light bus is calculated by CATIA 3D design mathematical model of motion simulation, and is compared with the test results, which verifies the correctness of the motion simulation results. The dynamic model of double wishbone torsion bar spring independent suspension is built in ADAMS/Car, and the liner stiffness is calculated by dynamic simulation. The comparison with the liner stiffness calculation results of motion simulation on CATIA proves correctness of the dynamic model. This method also applies to dynamic model validation of other type＇s independent suspensions.
