养护车起吊装置有限元模态分析

Maintenance Vehicle Lifting Device Finite Element Modal Analysis

通过Pro/E建立养护车起吊装置三维实体模型,并借助ANSYS Workbench有限元分析软件对模型进行模态分析,通过模态分析得到起吊装置模态参数,为进一步研究起吊装置振动特性、疲劳破坏和结构改进优化提供依据和参考。

This paper established by Pro/E ma-intenance vehicle lifting three dimensional solid model of device,and with the finite element analysissoftware ANSYS Workbench modal analysis,modal parameters obtained by lifting device modalanalysis,for further study lifting device vibrationcharacteristics,and structural fatigue failure improvedoptimization provide the basis and reference.
