Then, a size of the device’s main structure and the working parameters were determined. Taking advantage of virtual prototyping technology and simulation software platform Pro/E, a virtual prototype of the new tamping unit was created and kinematics simulation was carried out. The results show that the new tamping machine which adopts hydraulic vibration technology of load sensing and stepless regulation of operating parameter can improve the wear of tamping bar by forced vibration and the strong swing drawback of the clamping cylinder.
