摘要
液压挖掘机工作装置的挖掘力是衡量液压挖掘机挖掘性能的重要指标之一,也是挖掘机用户购买挖掘机时考虑的重要因素之一。基于虚拟样机技术的液压挖掘机仿真分析能够真实地模拟该挖掘机工作装置的挖掘力。以某型液压挖掘机(20t级)为研究对象,应用仿真分析软件ADAMS对其工作装置进行动力学仿真分析。通过动力学仿真分析,得到各铰接点处和液压缸的受力情况及相关曲线,从而为铲斗、斗杆和动臂等结构的强度分析提供依据。
Excavating force of hydraulic excavator’ s working equipment is one of the important indicators of measuring the per-formance of hydraulic excavator,is also one of the important factors to consider when the users buy excavator.However,simulation of hydraulic excavator based on virtual prototype technology can truly simulate the excavating force of excavator’ s working equip-ment.Taking a certain type of hydraulic excavator （20t） as the research object,using simulation analysis software ADAMS to car-ry out dynamics simulation analysis on its working equipment,from which the variance of forces at key articulated points and hy-draulic cylinder were presented.The analysis results can provide basis for further strength analysis of excavator components.
