摘　　要：基于井下某硬岩掘进机实际工况下的跟车振动测试,采用环境模态识别方法对其关键部件回转台进行了模态分析。获得的前多阶模态参数提示掘进机传动系统设计时,应适当避开第1阶、第9阶频率,以降低回转台机械噪声和磨损。Base on the vibration test of a working roadheader underground, ambient excitation-based parameter identification techniques were applied to identify the modal parameters of the revolving platform on the machine. In order to decrease mechanical noise and wear, it is suggested 1 st and 9th modal frequency of the platform when design the drive system parameters of the to avoid the machine.
