液压支架试验台是液压支架出厂检验和型式试验的重要设备,立足于对插拔销式活动梁的销轴孔位置的优化,针对销轴孔竖直方向不同位置进行仿真,得到随着销轴孔位置变化的最大等效应力和最大位移曲线。容易看出,在销轴孔中心距离底面410 mm时最大应力值最小,而随着销轴孔位置的提高,最大位移值越来越小。由于最大位移量的变化比较小,即对试验台刚性影响有限,得出,在不考虑其他设计因素的前提下,销轴孔中心距离底面的最优距离为410 mm。
Hydraulic support test stand is the hydraulic support factory inspection and type testing of important equipment, based on the plug pin movable beam pin hole location optimization, pin hole for different positions in the vertical direction for simulation, with the pin The maximum equivalent stress and the maximum displacement curve of hole position change. It is easy to see that the maximum stress value is the smallest when the center of the pin hole is 410 mm from the bottom surface, and the maximum displacement value is getting smaller and smaller as the pin hole position is increased. Because the change of the maximum displacement is relatively small, which has a limited impact on the rigidity of the test rig, it is concluded that the optimal distance from the center of the pin hole to the bottom is 410 mm without considering other design factors.
