摘　　要：针对现有的四连杆型液压支架的立柱及顶梁不能承受侧向力,以及侧向力通过掩护梁传递给连杆易造成倒架和支架机构损坏的原理性缺陷,提出了一种基于3-RPC三平移并联机构的新型双并联液压支架,除了可承受垂直压力外,还可承受来自其他方向的侧向分力。采用ADAMS对其进行运动学和动力学仿真,验证了该并联液压支架的设计符合煤矿井下支护的要求,在技术上是可行的,为实体样机的设计提供了参考。Since the column and the top beam of the present four-bar hydraulic support fail to bear the lateral force, thus the lateral force transfer to the rod via the shield beam, which often brings about falling down of the support or damage of support mechanism, a new-type double-parallel hydraulic support based on 3-RPC threetranslational parallel mechanism was proposed. It not only bore the vertical pressure but the lateral force from other direction. In addition, ADAMS was applied to carry out dynamics and kinematics simulation, and the results showed the parallel hydraulic support met the requirements of the support used in underground colliery and was feasible in technology. The proposed support offered reference for the design of physical prototype.
