声学法锚杆轴力监测装置的研究

Research on Acoustic Method of Bolt Axial Force Monitoring Device

针对现有锚杆轴力监测方法存在的不足,提出一种听不同频率声音判断锚杆轴力大小的新方法,阐明了监测装置的结构构造和基本原理,从模态、声学等方面进行了详细说明,并分析了监测人员所处监测角度、距离不同对监测效果的影响。

For the deficiencies of existing monitoring device, it proposed a new method that can judge the size of bolt axial force by listening different frequencies of sound, the basic principle,structural configuration, mode and acoustic of the monitoring device are clarified and introduced exhaustively. Finally, the influences of angle and distance of monitors are analyzed.
