摘要
应用有限元软件HyperWorks,对某船用升降设备进行模态分析,获得了该设备前6阶模态的固有频率、振幅及振型等动力学特性,为进一步动力分析求解提供了参数,并将模态分析结果与发动机激振频率对比,证明了其机械设计较为合理。
The finite element software HyperWorks is applied to conduct modal analysis of marine lifting equipment.The natural frequencies,amplitude and vibration modes of the first six modes of the equipment are obtained,which provides the parameters for further dynamic analysis and solution. Through the comparison between the modal analysis results and the engine excitation frequency,the mechanical design is reasonable.
