有限元分析在液黏调速离合器传动轴设计中的应用

摘要

Based on the comprehensive mechanical analysis of structure characteristics of Hydro-viscous clutch driven shaft,the mechanical model is established by the traditional mechanical analysis method and the dangerous section is pointed out. The more subtle stress and the strain rule of the shaft on the condition of bearing operation is revealed by the ANSYS finite element analysis. The two methods come to the similar analysis conclusion,which indicates that the modeling based on the ANSYS finite element analysis is reliable and provides theoretical basis and guidance for the reasonable design of the driven shaft and similar axial parts.%基于对液体黏性调速离合器被动轴结构特点进行分析的基础上,采用传统轴类零件力学分析方法,建立了力学模型,指出了受力集中的危险截面.为进一步分析其受力与应变特性,运用ANSYS软件进行了有限元分析,进一步揭示了液体黏性调速离合器被动轴在承载工况下的更加细微的应力与应变规律.两种方法获得了基本一致的分析结论,表明基于ANSYS有限元分析方法建模的正确性,为被动轴及类似轴类零件的合理设计提供了理论依据与指导.
