建立了某ZD型减速器主要零部件及整体结构的有限元模型,采用Lanczos法对减速器整体结构的自由模态进行了计算,通过计算找到了整体振动的薄弱部位,为减速器结构的改进设计及整体的动态响应分析提供了可靠的依据。
The finite element model of the main components and the overall structure of a ZD reducer was established. The free modal of the overall structure of reducer was calculated by Lanczos method. The weak part of the whole vibration was found by calculation, Design and overall dynamic response analysis provides a reliable basis.
