摘　　要：为了探究掘进机载荷内在的统计规律,对EBZ260TY型掘进机截割假岩壁进行实测与分析。通过识别掘进机截割臂右侧与截割臂上侧的载荷应力,运用一维载荷谱的编制理论,准确获取掘进机截割臂载荷变化规律,对掘进机的结构改进和优化具有参考价值。In order to research internal statistics rule of roadheader, carried through test and analysis when EBZ260TY type roadheader cut artificial rock. Load stress of starboard and upside of cutting arm on roadheader were identified by workout theory of one dimensional load spectrum, and truly obtain variational rule of cutting arm load on roadheader. It is helpful importance to structure improvement and optimization of roadheader.
