| Abstract: | 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. |
