TBM 刀盘系统动态特性及参数影响
Dynamic characteristics of TBM cutterhead system and its parametric influence
摘要
Abstract
A tunnel boring machine (TBM) cutterhead endures heavy impact loads during excavation.It vibrates fiercely and causes vital components to fail early.Therefore, it is indispensable to study the vibration characteristics of the cutter-head and the influence of mass and stiffness parameters at the design stage.For this purpose, the modal energy distribu-tions of each component were obtained by solving natural frequencies and vibration modes of each order by using the cou-pling dynamics model of the TBM cutterhead system.Next, the modal vibration modes of each order were distinguished, sensitive modal parameters were identified, and their influences on the first 10 frequencies were analyzed.The results show that the modal vibration of the cutterhead system is focused mainly in the medial orders, and the natural frequency corresponding to the pure torsional vibration mode is 57 Hz.Each vibration mode can be distinguished by its modal ener-gy, which is consistent with conventional vibration mode analysis.In addition, natural frequencies of orders 2~10 are af-fected mainly by pinion inertia and torsional stiffness of the input terminal.The vibration characteristics are more stable when the two values are equal to 1.1 and 1.3 times those in the original scheme,respectively.关键词
