The Structure Statics Analysis and Optimal Design of Hydraulic Support

Abstract

Hydraulic support is a key equipment of synthesis mechanization caving coal and safe production in modernization coal mine. In this paper, the parametric finite element model of ZZ10800/22/45 thin bedrock hydraulic support top beam was established by ANSYS Workbench. The distribution of stress and displacement were obtained by static analysis under the both ends load working condition. According to the FEM calculated results, the optimized mathematic model was developed and the hydraulic support top beam was calculated based on Goal-Driven Optimization(GDO) to propose a lightweight design. It is shown that the effects of lightweight design are obvious, as the optimized plan is in accordance with actual work condition by comparing the FEM check verification. This would provide a guidance and reference value for the research and development of hydraulic support products in the future.
