摘要
针对回撤掩护支架的使用要求,设计出大缸径双伸缩立柱。通过立柱模型,研究了大缸径双伸缩立柱的强度计算方法,完成对立柱缸筒、活柱稳定性及强度计算校核,其计算方法能为相关的设计提供理论依据。
Based on the request of haul hydraulic support, design large bore doubly-telescopic prop.According to the model,the strength calculation method of doubly—telescopic prop is studied, the strength calculation is fulfilled for the top prop and the middle cylinder. The calculation method supply reference for other design.
