%X TBM掘进时的重载冲击激励可能会造成刀盘剧烈振动进而影响掘进效率。由于物理实验的不可行性和理论分析的复杂性，计算机仿真是研究TBM主机振动特性的理想方式。基于多体系统动力学仿真平台ADAMS建立了TBM主机模型，对TBM的掘进过程进行了动力学仿真。仿真结果表明：刀盘径向振幅为10-1 mm量级比轴向振幅小一个量级；刀盘分体与中心块之间的径向作用力为102 kN量级比轴向作用力小一个量级且峰值频率不同；盾体与主梁之间的径向作用力为104 kN量级比轴向作用力也小一个量级，但刀盘分体与中心块之间的轴向作用力和盾体与主梁之间的轴向作用力结果类似。<br>The impact overloads when boring with Tunnel Boring Machine (TBM) may cause severe cutterhead vibration, which will further affect the efficiency of tunneling. Due to the non-feasibility of physical experiments and complexity of theoretical analysis, computer simulation is an ideal way to study the vibration characteristics of TBM mainframe. Therefore, a TBM mainframe model was built in this paper based on the multi-body system dynamics simulation platform ADAMS, and the TBM tunneling process was simulated. The simulation results show that the radial amplitude of cutterhead is at the 10-1 mm order, which is one order less than the axial amplitude; The radial force between the center part and other parts is at the 102 kN order, which is one order less than the axial force, and the summit frequency of this two forces is different; The radial force between the shield and mainbeam is at the 104 kN order, which is also one order less than the axial force, but the axial force between center part and other parts of cutterhead and the axial force between the shield and mainbeam is quite the same
