一种新型锚杆监测装置的研究

Research on a new type of bolt axial force monitoring device

针对多数矿井锚杆力监测装置存在结构复杂、成本较高且很难做到实时有效判断等问题,设计了一种可以通过不同频率的声音判断锚杆力大小的新型锚杆力监测装置。利用Pro-E软件建立监测装置的实体模型,使用ANSYS软件对监测装置进行静力学和模态计算,利用LMS Virtual.lab软件对该装置进行声学仿真分析。研究表明,该装置可行有效,适合实际推广使用。

Most bolt axial force monitoring devices have complex structure,high cost,and are difficult to achieve real-time and effective judgment.A new type of anchor force monitoring device was proposed,that can judge the anchor force at this time by listening to the sound of different frequencies.Pro-E software was used to establish the entity model of the monitoring device was studied,ANSYS software was used to carry out statics and modal calculation of the monitoring device,and LMS Virtual.lab software was used to carry out acoustic simulation analysis of the device.The results show that the device is feasible and effective,and suitable for practical promotion and use.
