摘要：

The energy absorption process of the energy absorption component of a ZQL anti-impact hydraulic support is not stable. A thread shear energy absorbing component is proposed, and three thread tooth types of triangle, rectangle and trapezoid are designed. Based on the single factor method, the energy absorption characteristics of three kinds of thread energy absorbing components under rock burst are obtained. It is determined that the energy absorption characteristics of trapezoidal thread energy absorbing components are stable and that the energy absorption effect is the best. Based on the parametric simulation analysis of screw diameter and pitch on trapezoidal thread energy absorption components, the influence of screw diameter and pitch on the energy absorption characteristics of energy absorption components was determined. Finally, it is found that the experimental results are basically consistent with the simulation results, which verifies the correctness of the simulation. This paper provides a theoretical basis for the design of energy absorbing components of ZQL hydraulic support.
