To study the stress and strain of the tail beam and the change of the movement state when coal gangue particles impact the tail beam of the hydraulic support, coupled with the differences of impact results between coal rocks with different materials, this paper uses the method of joint simulation by Hypermesh and Workbench. Firstly, using the software Hypermesh to pre-process the impact model, and then importing the grid file into the finite element analysis software workbench. Finally, using the Explicit Dynamic module of Workbench to simulate and analyze the impact behavior of different coal gangue particles. The results show that, compared with gangue, the stress and strain, as well as the dynamic response of the metal plate caused by coal is smaller. This study can provide a reference for the study of dynamic characteristics of hydraulic support, and a research basis for the realization of coal gangue vibration identification method.
