双伸缩立柱螺纹强度计算

摘要

通过分析双伸缩立柱，研究其螺纹连接处的强度计算方法，能提高立柱的使用寿命，降低损坏率，其计算方法能为双伸缩立柱的设计提供理论依据。%According to the analysis of doubly-telescopic prop, the strength calculation method of screw thread joint is studied, which improves the quality and reduces the failure rate of doubly-telescopic prop. The calculation methods supply reference for the design of doubly-telescopic prop.
