This article used the lumped mass method and FEM to model and analyze a kind of pow-er two branch transmission system.Based on this,the natural characteristics of the system were ana-lyzed,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 ra-ted speed,providing guidance for the transmission system work properly and avoid dangerous work-ing areas.
