TBM推进系统动力学特性分析
Dynamic characteristics analysis of TBM thrust system
摘要
Abstract
To research the response of the TBM′s thrust system to initial conditions, a multiple-degree-of-freedom coupling dynamic model, which contains the main frame and a pair of grippers, was established considering the external stochastic excitations and variable stiffness between the gripper and the rock.Dynamic responses were calculated by using a numerical method and were analyzed in different initial conditions.The X and Y directions strongly influence the attitude of the thrust system.The deflection of the thrust system was up to 0.18 m when the initial angle was 0.01 m and up to 1.4° when the initial angle was 1°.This condition presented a great challenge to the adjustment of the angle of the TBM attitude and even caused the machine to deviate from the planned route and be unable to complete the excavation work.This research provides theoretical guidance for TBM attitude adjustment.关键词
