功率二分支传动系统固有特性分析

Natural Characteristics Analysis of Power Two Branch Transmission System

通过集中质量法以及有限元分析方法,分别对某功率二分支传动系统进行建模分析,以此为基础开展其固有特性分析,并对集中质量法、有限元法两种方法的模态分析计算结果进行对比分析,得到该功率二分支传动系统在额定输入转速状态下工作不会发生共振的结论,为传动系统避开危险工作区域正常运转提供指导性意见。

This article used the lumped mass method and FEM to model and analyze a kind of power two branch transmission system.Based on this,the natural characteristics of the system were analyzed,and the modal analysis results of the lumped mass and FEM were compared and analyzed.It was concluded that the power branch transmission system would not resonate when working at the rated speed,providing guidance for the transmission system work properly and avoid dangerous working areas.
