切片参数与斗轮及使用参数均有关。它直接影响斗轮挖掘机有效生产率和挖掘能量消耗。一、能量消耗与切片断面形状的关系进行分析时,假设物料线切割阻力K_L与切片断面形状无关。据此,可用研究平均切削刃长度来代替研究挖掘能量消耗。1.平均切削刃长度和最佳切片断面形状切削刃长度与切片断面形状有关。切片断面形状系数d表示切片宽度b与斗轮轴高度上 The slice parameters are related to the bucket wheel and the use parameters. It directly affects the bucket bucket excavator’s effective productivity and energy consumption. 1. When analyzing the relationship between the energy consumption and the cross-section shape, assume that the material line cutting resistance K_L is not related to the cross-sectional shape of the slice. Based on this, it is possible to study the average cutting edge length instead of investigating the energy consumption of excavation. 1. Average cutting edge length and optimum slicing section shape The cutting edge length is related to the section shape of the slicing section. Sectional cross-sectional shape factor d indicates slice width b and height of bucket shaft
