为了满足液压支架采高和承载力的增大,大缸径立柱得到了广泛的使用,立柱是液压支架的主要支撑部件,立柱的大小决定了支架的可承载强度和高度;采用厚壁来满足立柱的强度要求。利用有限元计算软件对大立柱厚壁进行了有限元力学分析,使厚壁满足了立柱力学性能要求,同时优化了结构,节省了成本。 In order to meet the increase of hydraulic support mining height and bearing capacity, large diameter column has been widely used, the column is the main support component of the hydraulic support, the size of the column determines the support of the stent strength and height; thick wall to meet the column The strength requirements. Finite element mechanics analysis of thick wall of large pillar was carried out by using finite element software to make the thick wall meet the requirements of mechanical property of column, meanwhile, the structure was optimized and the cost was saved.
