摘　　要：利用六个激光位移传感器测量金刚石串珠绳切割花岗石过程中,加工弧区内串珠绳的振动信号,从频率和振幅两个方面分析了张紧力、导轮间距以及串珠绳直径等加工参量对串珠绳切割振动的影响。实验结果表明,加工弧区内串珠绳的振动频率主要由串珠绳线速度及单位长度串珠个数的乘积来决定,本实验中的加工参量对振动频率没有明显影响。随着张紧力减小和导轮间距的增加,弧区内串珠绳的振动幅度会随之增加;随着串珠直径的增加,相同加工参数条件下,串珠绳的振动幅值也有所增加。In this paper, vibration signals in the processing arc for the diamond wire saw are collected with six laser displacement sensors. The influence of processing factors, included tension force, the space between guide wheel and wire diameter, on the vibration of diamond wire saw is researched through power spectrum and root mean square value （RMS）. The research results show that the mainly frequences of diamond wire vibration is the product of wire speed and the number of bead per unit length and have be little influenced by the processing factors. Vibration amplitude increase with the decrease of tension force and the increase of space of guide wheel and wire diameter.
