Trackless vehicles have been widely used for the underground mining in many coal-rich countries. However, their vibration is violent and this vibration could affect the driver's health and reduce the working efficiency. Therefore, how to solve this question about the vibration and shock has become an urgent and important thing. In this paper, a type of tubular constrained damping engine mount is designed and first used in the underground trackless vehicles. This tubular damping structure is made of three layers, the external and internal layer are made of steel and the middle layer of natural rubber is sandwiched between them. To know about the vibration-reducing performance of the new designed mounts, the real vehicle test was performed under two working conditions. The results show that the two rear mounts could obtain good vibration isolation effect, whereas the performance are sometimes poor in a certain direction for the two front mounts because of the vibration energy coupling in different directions. Further research is to optimize the parameters of the tubular constrained damping engine mount to make the vibration energies from different directions decoupled.Keywords
