以某两柱掩护式液压支架为研究对象,利用Pro/E软件建立支架的三维模型,通过相应的配置设置将其导入到ANSYS Workbench中,然后根据煤矿用液压支架通用技术条件,对3种不同工况下的液压支架进行有限元分析,得出不同工况下的等效应力分布规律,找出液压支架最容易破坏的位置,并对支架原有结构提出改进的措施。
Taking a two-column protective hydraulic supporter as the research object, a three-dimensional model of the supporter was established by using Pro / E software and imported into ANSYS Workbench through corresponding configuration settings. According to the common technical conditions of the hydraulic supporter for coal mine, Under the condition of hydraulic support, the finite element analysis was carried out, and the distribution law of equivalent stress under different working conditions was obtained. The most vulnerable position of hydraulic support was found out, and the original structure of support was put forward to improve measures.
