Research on a new type of bolt axial force monitoring device

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.
