摘　　要：随着煤矿开采深度的增加对液压支护设备抗压能力提出更高的要求,为了提高矿用支护设备的力学性能及减缓冲击地压对其造成的破坏影响,本文通过对现有预折纹吸能构件内部布置不同支撑物对其力学性能及吸能效果进行了研究分析,采用理论计算与数值模拟相结合的方法加以验证。最终,结果表明吸能构件增加支撑物后降低了载荷波动增强了吸能性能,提高了支护设备的抗冲击能力。With the increase of coal mining depth,higher requirements are put forward for the compressive capacity of hydraulic support equipment.In order to improve the mechanical properties of mine support equipment and mitigate the damage impact of rock burst on it,this paper analyzes the mechanical properties and energy absorption effects of existing pre-folded energy absorption components by placing different supports inside them.The method of theoretical calculation and numerical simulation is used to verify the results.Finally,the results show that the load fluctuation is reduced,the energy absorption characteristics are enhanced,and the impact resistance of the support equipment is improved.
