摘　　要：从二自由度振动微分方程建立、悬架静态偏频计算、动刚度对悬架垂向振动影响分析三个方面入手,对车辆垂向振动进行了分析,找出了其共振原因,提出了具体改进方案。Starting from the two-degree-of-freedom vibration differential equation,the static frequency deviation of suspension and the influence of dynamic stiffness on the vertical vibration of suspension,it analyzes the vertical vibration of the vehicle,finds out the cause of its resonance,and puts forward the concrete improvement scheme.
