摘要
为了研究液压挖掘机结构的动态特性,借助有限元软件ANSYS对液压挖掘机进行了模态分析。考察了其固有频率和振型,评估其动态特性,通过改进结构,改善了其动力学性能。
To study the structural dynamic characteristics of hydraulic shovel, the mode of hydraulic shovel was analyzed in virtue of ANSYS, the natural frequency and the model of vibration were studied, and the dynamic characteristics was evaluated and improved in virtue of structural dynamics theory.
