Suspension Stiffness Optimization of Underframe Equipments in High-speed Passenger Car

  • 摘要: 建立了考虑构架及弹性车体的车辆系统简化模型,分析了车下设备采用弹性悬吊和刚性悬吊两种方式对车体振动的影响。研究表明:车下设备弹性悬吊方式能够在一定的频率范围内有效降低车体的弹性振动。采用传递函数理论,推导了车下设备最优悬吊刚度的数学表达式,分析表明,车下设备最优悬吊刚度对应的频率应接近车体的一阶弯曲频率。结合有限元和Simpack软件建立了高速试验列车的三维刚柔耦合动力学模型,并对试验车辆进行了滚动台试验测试,仿真结果与试验结果能够很好的吻合。
