000014379 520__ $$2eng$$aThe lumped parameters dynamic model of gripper cylinder in Tunnel Boring Machines is established in which the interaction with the rock and the variable stiffness of structures are considered. The correlation between the dynamic behavior and the variable stiffness of the cylinder due to interaction with the rock, the oil, the seals, the copper guide sleeve and the length of piston rod is numerical discussed. The results show that the natural frequency of the gripper cylinder is mainly affected by the equivalent stiffness of the seals and the oil. The fluctuation of the loads between the cylinder and piston rod is investigated, which provides the guide for the damage analysis of the gripper cylinder in TBM.
