回转式灌装机主驱动齿轮的模态分析

摘要

The process of the modal analysis based on ANSYS software are introduced. The finite element model of the host-drive gear of the rotary filling machine is established. Its modal analysis is made, the natural frequencies and the modal shapes are obtained. Furthermore, the influence of the gear-tooth width to the natural frequencies is analyzed. This will provide some theoretical datum and methods for avoiding resonance vibration of the rotatory filling equipment.%介绍了ANSYS软件中模态分析的步骤；建立了回转式灌装机主驱动齿轮的有限元模型,并对其进行了模态分析,得到了齿轮的固有频率和振型；进一步分析了齿宽对齿轮固有频率的影响规律,为避免灌装机发生共振提供了理论数据和方法.
