隧道掘进机(tunnel boring machine，TBM)技术是一种安全高效的隧道工程施工方法。在TBM掘进中，滚刀刀盘系统与岩石相互作用时会产生振动现象，其振动特性与破岩机制均会影响到TBM的掘进效率和刀盘刀具的使用寿命。通过制作大尺寸砂浆材料试件，采用自主研制的TJ-TS500型线性切割试验平台，设计较为精细的振动测试系统，进行滚刀线性切削试验。试验方案考虑切深、切割速度以及试样节理特征等因素，同时在切削过程中对滚刀三向力以及试样的振动信号进行监测。通过对采集的振动信号进行快速傅里叶变换（fast Fourier transformation，FFT），分析不同切削参数条件下的滚刀破岩振动特性。

The tunnel boring machine (TBM) technology is a safe and efficient construction method in tunneling. During the excavation, the cutter system will generate vibration when interacting with the rocks. The vibration characteristics and rock breaking mechanism will affect the tunneling efficiency of the TBM and the service life of the cutters and cutterhead. The selfdeveloped TJTS500 linear cutting test platform is used to design a fine vibration test system to carry out linear cutting test of disc cutter. The different combinations of cutting depth, cutting speed and joint characteristics of the sample are considered, and the threeway force of the disc cutter and the vibration signal of the sample during rolling cutting are monitored. Fast Fourier Transformation (FFT) is performed on the collected vibration signals to analyze the rock breaking vibration characteristics of the disc cutter under different cutting parameters.
