综合应用虚拟样机技术和有限元分析方法对QY200-14-31型液压支架三维模型进行分析和研究,以掌握其在工作状态下主要部件的受力情况。通过动力学分析软件,对主要部件铰接处受力的变化规律进行分析总结,对3个极限位置模型的应力分布、位移进行比较分析得到柱窝处作用力特点。
The three-dimensional model of QY200-14-31 hydraulic support was analyzed and studied by using the virtual prototype technology and the finite element analysis method synthetically to grasp the stress of the main components under the working condition. Through the dynamic analysis software, the change rule of the force at the hinge of the main components is analyzed and summarized. The stress distribution and displacement of the three extreme position models are compared and analyzed to get the force characteristics at the column and socket.
