重载冲击激励下 TBM 刀盘振动特性的影响因素分析
Analysis of influencing factors of vibration behaviors of TBM cutterhead under heavy impact loads
摘要
Abstract
A cutterhead is one of the key parts of a tunnel boring machine ( TBM) .The performance of the cutter-head has a great impact on the boring capability of the TBM.The torque and thrust of heavy-load impact on the cut-terhead in the tunneling process will cause severe vibration.This leads to the decline of service life and even de-struction of the cutterhead, which affects the boring efficiency.In this paper, a TBM mainframe model under com-plex factors of"Northwest Liaoning"water diversion works was built based on the multi-body system dynamics sim-ulation platform ADAMS.The influence of different factors including the rotation speed of cutterhead, cutterhead to-pology, the speed fluctuation and non-synchronization of small driving gears on the vibration characteristics of cut-terhead was also discussed.The simulation conclusions demonstrated that in order to reduce the vibration of cutter-head, the"coin"topology should be applied.However, when controlling TBM the fluctuation of rotational speed and non-synchronization of driving gears should be avoided as much as possible.The tunneling should be conducted under low rotational speed of cutterhead.关键词
