摘　　要：建立了高速综合检测列车牵引变压器及其冷却单元与车体间的刚柔耦合力学模型,研究了利用模态叠加原理计算车体和附属设备耦合系统振动加速度的计算方法。利用数值仿真方法分析了牵引变压器和冷却单元与车体间的连接刚度对车体和设备振动的影响。The rigid-flexible coupling mechanics model between the traction transformer together with its cooling unit and the carbody of the high speed comprehensive inspection train is set up. The calculation method for the vibration acceleration of the coupling system of the carbody and the appurtenances is researched with the modal superposion principle. The numerical simulation method is used to analyze the effect of the connection stiffness between the traction transformer together with its cooling unit and the carbody on the vibration of the carbody and equipment.
