基于Abaqus的谐波齿轮环形柔轮变形仿真分析

Simulative Analysis about Deformation of Ring-flexspline Harmonic Gear Based on Abaqus

在航天工程中,要求精密传动装置具有体积小和承载能力大的特点,环形谐波齿轮在这些方面占有优势。针对目前国内对环形柔轮变形和应力尚缺乏系统的理论研究,在对基于传统的力学模型和实验方法而得到的理论模型进行分析的基础上对柔轮结构进行优化设计,利用有限元方法进行仿真分析,得到环形柔轮初始变形和应力分布规律,为精密谐波齿轮的设计提供可靠的依据。

In space engineering,the precise transmission device needs the volume to be as small as possible and the bearing capacity to be as large as possible.The ring-flexspline harmonic gear is superior in these aspects.At present the systematic fundamental research on the deformation and stress of ring-flexspine harmonic gear is still lacked at home.Based on the theoretical model obtained through traditional mechanical model and experimental method,this paper analyzes the initial deformation and stress distribution of the ring-flexspline using finite element method and optimizes the structure of the ring-flexspline.The results are helpful to the nice harmonic gears design.
