摘　　要：轮式装载机铲斗的铲掘受力是一个复杂的变化过程。以装载机铲斗为研究对象,对铲斗铲掘过程进行受力分析。针对不同铲掘过程的受力变化情况,采用库伦土压力理论,对铲斗不同阶段的运动和受力大小进行分析,为装载机的铲掘作业提供了理论依据。Forces during digging procedure of a loader bucket are complicated.Targeting at a loader bucket,force analysis is conducted for its digging procedure.Aiming at the force changing conditions in different digging processes,Kulun soil pressure theory is applied to study the movements and forces levels in the processes,which provides theoretical basis for digging operation of loaders.
