摘　　要：对可代表六柱混合支撑掩护式、四柱支撑掩护式及混合支撑掩护式、两柱掩护式液压支架的一般架型在五种工况下的受力状态分别进行了分析，给出了支架在任一工作高度下顶梁、掩护梁、底座等构件的力学模型，为应力计算和强度校核提供了必要的力学数据。By analysis of the features of mechanics of a general type of hydraulic support under five loading conditions, Which can represent the mixed support of supporting and shield with 6 or 4 columns, the supporting-shield support with 4 columns and the shield support with 2 columns, the paper sketches some models of mechanics for the structural component of hydraulic support such as roof beams, shield beams and pedestals in different levels of height. The models can supply detailed mechanics data for stress calculation and strength examination.
