摘要
为研究液压挖掘机结构的动态性能,笔者借助Pro/E软件对液压挖掘机动臂进行了模态分析。考察其固有频率和振型,评估其动态特性,为动臂结构的进一步优化、改进设计提供依据。
In this article, the modal analysis of hydraulic excavator arm was analyzed with Pro/E,the natural frequency and vibration mode were studied, and the dynamic characteristics was evaluted. Thus a foundation for the further optimization was provided, the structural design of hydraulic excavator arm could be improved.
