摘　　要：针对某款国产MPV车型在急加速工况下的车身及后桥处的异常振动,利用ADAMS建立了包括传动系、发动机、悬架、车身、轮胎等部件的整车综合动力学模型。运用ADAMS中的Insight模块对中间支承刚度进行了敏感性分析,确定了中间支承轴向刚度和径向刚度对整车振动的影响程度,最后对中间支承径向刚度与轴向刚度进行了优化以达到改善整车NVH表现的目的。A multibody dynamic model made of transmission,motor,and suspension is built in ADAMS.ADAMS/Insight is used and DOE is done to observe the effect of intermediate support’s stiffness on the vibration of the car.The optimization is done to the radial and axial stiffness of the intermediate support and the result shows that vibration is decreased,which shows the method is useful to improve the NVH performance of the whole car.
