In order to improve the sensing sensitivity of the fracture situation of the mining ring chain link under different working conditions,an automatic sensing technology of the fracture situation of the mining ring chain link is proposed.According to the size of mining ring chain link,the geometric model of mining ring chain link is established by using three-dimensional software.According to the relative position of the mining ring chain link,a probe for detecting the fracture situation of the mining ring chain link is configured.According to the standard of mining ring chain link,the mesh division of tetrahedron butt link is adopted,and the principle of ultrasonic wave propagation in medium is used to formulate a scheme for sensing the fracture situation of mining ring chain link,which realizes the automatic sensing of the fracture situation of ring chain link.The analysis results show that when the automatic sensing technology in this paper is adopted,the sensing sensitivity of the fracture situation of the mining ring chain link can reach more than 80%,which can ensure the quality of the mining ring chain link.
