| 摘 要： | 依据我国煤炭行业标准MT313-1992《液压支架立柱技术条件》,通过建立双伸缩立柱计算模型,研究了双伸缩立柱强度计算方法,以某360型双伸缩立柱为例,根据其结构特点,分别进行了全行程伸出加1.5倍额定轴向载荷时活柱、中缸和外缸强度计算。结论认为,该型立柱强度储备良好,计算方法合理,可为相关设计计算提供依据。

| Abstract: | Based on the China coal industry standard MT313-1992,through establishing mechanics model,the strength calculation method of doubly-telescopic prop is studied.Based on the structural features,the strength calculation is fulfilled for the top prop,the middle cylinder and the bottom cylinder of a 360-type doubly-telescopic prop,which is in the state of whole travel and loaded 1.5 times axial rated load.The result shows that the 360-type doubly-telescopic prop has sufficient safety margin.The calculation metho... |
