摘要
液压支架是综采工作面最重要的支护设备,由于煤矿井下环境恶劣,综采工作面液压支架推移装置受力比较复杂,结构自身的力学性能对液压支架的正常运行影响非常大,采用有限元分析法对综采工作面液压支架推移装置进行力学分析,采用ANSYS Workbench对液压支架推移装置进行数值模拟,分析了推移装置中推杆处的最大应力和变形,得出结构在受力时的危险点,对结构的优化设计,提高推移装置的使用寿命和检修推移装置等具有重要意义。
Hydraulic support is the most important support equipment for the fully mechanized mining working face.Due to the harsh underground environment of the coal mine,the force of hydraulic support pusher jack of the fully mechanized working face is more complex;and the mechanical properties of the structure itself have a great influence on normal operation of the hydraulic support.In this paper,mechanical analysis of hydraulic support device is conducted by the finite element analysis,and the numerical simulation is performed by using the ANSYS Workbench.The maximum stress and deformation of the pushrod are analyzed to obtain the danger point of structure under force.It is of great significance for the optimal design of the structure,and to improve the service life and maintenance of the pusher jack.
