多工况下挖掘机驱动桥壳有限元分析

Finite Element Analysis of Excavator Driving Axle Housing under the Multi Work Condition

为了提高模型设计可靠性,以某型挖掘机驱动桥壳为研究对象,运用可靠性干涉原理建立驱动桥壳的可靠性模型,并将驱动桥壳模型关键结构尺寸参数设置为随机变量,研究了桥壳应力、应变和参数灵敏度变化规律。

In order to improve the reliability of model design,a certain type of excavator driving axle housing is regarded as the research object,the reliability interference principle is used to establish a reliable model of drive axle housing,the axle housing model size parameters are regarded as random variables,the stress and strain change rule and parameters sensitivity variation of axle housing model are studied.
