摘要
文章首先对液压支架进行了受力分析,运用三维建模软件Solidworks建立三维实体模型,并介绍了一种顶梁偏载、底板两端约束的典型载荷工况。其次,运用ANSYS Workbench与ANSYS APDL对液压支架进行有限元的交互分析,并拾取等效应力最大值处的节点,追踪此节点的等效应力变化趋势。结果表明,前连杆与掩护梁连接的销轴处的等效应力值较大,符合综采的实际情况。文章在材料性能、工艺生产方面上提出了改进措施,有效提高了液压支架的使用寿命。
Firstly,the force analysis of hydraulic support was conducted,and the three dimensional model was built by software Solidworks.The typical load condition was also introduced.Secondly,conjoint finite element analysis of hydraulic support was conducted between ANSYS Workbench and ANSYS APDL,and the maximum von mises node was conformed to view the trend graph.The result concluded that the maximum von mises existed on joint between front track rod and caving shield,and it was conform to the truth.The improving steps in terms of material and processing were put forward to enhance the service time of hydraulic support.
