摘　　要：通过对ZY9400/28/62型掩护式液压支架内伸缩梁的运动进行仿真研究,得出伸缩梁与顶梁之间横向和纵向间隙对内伸缩梁运动的影响规律;根据模拟支架压架试验工况,对内伸缩梁进行应力分析。结果表明:该内伸缩梁可以满足破碎顶板的支护要求。The influence law of horizontal and vertical gaps between inner telescopic girder and canopy on telescopic girder movement is found by simulation on ZY9400/28/62shield support. And then, analyzes the stress distribution of telescopic girder through simulation of press support test. Results show the support can fulfill the need of broken roof.
