摘　　要：以流体动力学为理论依据,阐述了大型矿用挖掘机风道压力损失的计算方法。以35 m3挖掘机通风除尘系统为例,建立了风道模型并计算了风道的沿程摩擦阻力及局部压力损失,同时也进一步验证了35 m3挖掘机风道设计的合理性。This paper is based on the hydrodynamics, which formulate the computational method of the pressure loss of the large mining excavator. We establish the model of the 35 minmining excavator air flue and calculate the frictional resistance along the flue and the local pressure loss. This research verifies the reasonableness of the design of 35 min mining excavator air flue.
