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 explore the inherent statistical rules of boring machine load, the EBZ260TY boring machine was used to measure and analyze the fake rock wall. By recognizing the load stress on the right side of the cutting arm and the upper side of the cutting arm, the one-dimensional load spectrum theory can be used to accurately obtain the law of load variation of the cutting arm of the boring machine, which is of reference value to the structural improvement and optimization of roadheader .
