In the whole process of coal mining, hydraulic support, as the supporting equipment of coal mining, its high strength and high safety directly determines the production safety of coal mining operations.It is found that the shield beam is the weak part of the hydraulic support, especially when the top beam is subjected to torsion load.This paper cover beams under torsion load the statics analysis and topology optimization analysis, and based on this, advances the structure optimization, and the optimized scheme under the same conditions of statics analysis. Compared with the analysis results of the optimization scheme, it is shown that the maximum stress is reduced by 24.46%, while the weight is reduced by 194kg, the maximum displacement is also reduced, and the optimization result is the most ideal. Provide the technical support for the overall optimization of hydraulic support, complete the reinforcement structure overall lightweight design targets at the same time.
