摘　　要：根据液压支架强度加载方法,建立了四柱式支撑掩护式液压支架的空间力学模型,对支撑掩护式液压支架顶梁扭转工况进行受力分析,得出掩护梁各个铰点处的支反力;基于Abaqus有限元计算软件,结合zz5000液压支架,对扭转工况下支撑掩护式支架掩护梁进行分析,得出,此支架掩护梁在扭转工况下强度不满足要求。研究方法可为液压支架设计及研究提供参考。According to the strength loading methods of hydraulic support, spatial mechanical model of four-column supporting and shielding hydraulic support was established. Based on the model, forces of supporting and shielding hydraulic support during torsion were analysed and reaction forces of each hinged points of caving shield were obtained by using mathematic numerical software. Furthermore, on the basis of finite element calculation software Abaqus, we studied the supporting and shielding hydraulic support during torsion and found that the caving shielding during torsion cannot meet the requirements. These methods could provide references for design and study of hydraulic support.
