ANSYS analyzes the setting of hydraulic bumper for electric traction shearer

In order to solve the problem of unreasonable setting of the shearer, this paper studies the theory that the best selection of the range of pre-tightening coefficient is 0.5-1.1. After ANSYS finite element analysis and verification, the pre-tightening coefficient and the maximum contact pressure of the binding surface and the opening value are determined, and the pre-tightening coefficient is 0.5-1.1 to meet the requirements of the project, which has some rationality.
