摘要
液压支架是综合机械化采煤工作面的支护设备,双伸缩立柱是液压支架上的主要部 件之一。在分析了双伸缩立柱受力的基础上,建立了双伸缩立柱临界载荷计算的数学模型,提出了 临界载荷的计算方法。
Hydraulic powered support is the supporting equipment of integrated mechanized mining face. Dual-extension hydraulic legs is one of key parts of powered support, based on the analysis of loading acting on dual-extension hydraulic legs, the paper builds mathematical models of calculating critical loading, and presents calculating methods of critical loading.
