摘要
为了准确和全面把握超高端液压支架的大缸径双伸缩型立柱的强度性能,在充分考虑了焊缝和导向环等关键细节组件受载特性的基础上,构建了立柱有限元模型。通过静态中心过载压缩性能及偏心加载性能的仿真分析,指出了立柱在活柱的结构连接部位易产生较大的接触应力,并且在中缸和活柱底端可能出现导向环、动密封与缸体脱离接触。
In this paper, the finite element model of a doubly-telescopic leg of ultra-advanced large mining-height hydraulic support was established for exhaustive and accurate strength analy- sis, with the consideration of stress situation of key components such as welds and guide rings. The simulation analysis of legs under static center-overload or eccentric load showed that the lar- ger contact stress easily formed at structural connections in mobile column, which possibly caused the non-contact of guide rings and dynamic sealant with cylinder body.
