大型斗轮挖掘机上部结构静动力分析

Analyses of Both Dynamic Force and Static One on Upper Structures of the Large Bucket Wheel Excavator

以ＷＤＬ９５０（３０／５）型斗轮挖掘机为样机，建立了其上部有限元模型，并对其进行了静动力分析，进而通过动力响应的计算给出了斗轮机主要部位采用不同动力系数的参考值。

Taking WDL950(30/5) bucket wheel excavator as a sample machine, a finite element model of its upper part is established, with its both dynamic and static forces analyses being given. Accordingly, through the calculations of the dynamic responses, the reference values are presented as far as the different dynamic factors being concerned with those important parts of this model bucket excavator.
