介绍液压支架截面的力学模型,分析截面在外荷载作用下的正应力、剪应力分布,对液压支架的受力状态进行有限元分析,根据分析结果选择截面优化策略,给液压支架的截面参数设计提供理论依据。
The mechanical model of hydraulic support section is introduced. The normal stress and shear stress distribution of the section under external load are analyzed. The finite element analysis of the hydraulic support is carried out. According to the analysis results, the section optimization strategy is selected to provide the cross-section parameter design of hydraulic support Theoretical basis.
