摘　　要：针对煤矿斜巷运输现状,在分析现有跑车防护技术和无轨运输事故统计资料的基础上,采用高性能纳米吸能材料,设计了一种适用于矿井斜巷长坡无轨胶轮车失速安全防护的纳米吸能摩擦板。利用 LS-DYNA 碰撞仿真技术,对其进行了有限元优化设计,并进行了实车碰撞试验。试验结果表明,该纳米吸能摩擦板具有无轨胶轮车失速时的阻挡、导向和缓冲功能,可为无轨运输安全防护建立行业及产品标准提供参考。In view of the present situation of inclined roadway transportation in the coal mine,based on the analysis of the technology of protecting the uncontrolled running vehicle and the statistics of trackless transportation accidents,a kind of nanometer energy-absorbing friction plate was designed by using high-performance nanometer energy-absorbing material,which was suitable for the safety protection of the uncontrolled running trackless rubber-wheeled vehicle on long-slope inclined roadway in mine.LS-DYNA collision simulation technology was applied to carry out finite element optimization design,and real vehicle collision test was conducted.Test results showed the nanometer energy-absorbing friction plate possessed the blocking,guiding and cushioning function.It could offer reference for establishing industry and product standard for trackless transportation safety protection.
