盘形滚刀的垂向振动对于全断面隧道掘进机的贯入度和破岩效率有一定的影响，为了研究影响滚刀垂向振动的因素，首先建立盘形滚刀垂向三自由度振动模型，得到盘形滚刀刀圈与刀体、圆锥滚子轴承和刀轴的等效质量和刚度，利用MATLAB软件对该振动模型进行仿真，得到滚刀各部分的振动位移，并通过试验得到滚刀各部分振动位移与仿真的结果趋势一致。结果表明：滚刀的刀圈加刀体的最大振动位移量为2.8×10-4 m，轴承最大振动位移为2.1×10-4 m，当滚刀的轴承刚度增大3倍时，各部分最大振动位移减少约50%，增大刀圈刀体刚度时，各部分最大振动位移减少约12%，盘形滚刀减振需要增加轴承和刀圈刀体的刚度。研究结果为盘形滚刀的振动测量提供了一种有效方法，对滚刀的设计具有重要的指导意义。
Abstract
The vertical vibration of a disc cutter has certain influence on the penetration and rock breaking efficiency of a full-face tunnel boring machine.In order to study the factors affecting the vertical vibration of cutter, a three-degree-of-freedom vertical vibration model for the disc cutter was established, and the equivalent masses and stiffnesses of the disc cutter ring together with cutter body, tapered roller bearing and cutter shaft were presented.The mass and stiffness of the cutter were simulated by using the MATLAB software, and the vibration displacement of each part of the cutter was obtained.The simulated vibration displacement of each part of the cutter is consistent with the
experimental results. The results show that the maximum vibration displacement of the cutter’s ring and body is 2.8×10-4 m and the maximum vibration displacement of the bearing is 2.1×10-4 m.When the rigidity of the cutter’s bearing increases by three times, the maximum vibration displacement of each part decreases by about 50%.When the rigidity of
the cutter ring and body increases, the maximum vibration displacement of each part decreases by about 12%.To reduce the vibration of the disc cutter
it needs to increase the rigidity of the bearing as well as the cutter ring and body. The results provide an effective method for the vibration measurement of disc cutters and have important significance for cutter design.
