摘　　要：以掩护式液压支架为研究对象,分析支架可能出现的各种姿态,建立支架某一姿态的运动学数学模型,计算出支架各部件关键点处的空间位置,结合三维建模软件UG建立几何模型,并对支架进行运动仿真。通过仿真可知,顶梁倾角的改变,对支架的梁端距变化量、平衡千斤顶连接耳座的中心距、立柱倾角均有一定的影响。Taking a shield hydraulic support as the study object, the paper analyzed all possible postures of the support, and established a kinematic math model of one posture of the support. In addition, it calculated the space positions of key points of support components, and conducted the kinematic simulation of the support based on 3D modeling software UG. The simulation results showed that the variation of obliquity of the top girder had some influence on the distance between girder ends of the support, central distance between connecting lugs of the balancing jack as well as the column obliquity.
