摘要

通过Hypermesh 划分网格并使用Abaqus 完成对谐波减速器的瞬态分析。基于瞬态分析结果，确定了柔轮危险点的位置，提出了一种提取并合成柔轮危险点应力谱的方法。通过对应力谱进行雨流计数，组合修正P-S-N 曲线与Miner 疲劳损伤累计理论，预测了谐波减速器柔轮的寿命。预测结果与国内谐波减速器的产品的寿命相近。该研究工作为谐波减速器柔轮疲劳性能定量评估提供了参考依据。

Abstract

By using Hypermesh to mesh the harmonic reducer and utilizing Abaqus to complete its transient analysis. Based on the results of transient analysis,the position of the dangerous point of the flexspline is determined,a method of extracting and synthesizing the stress spectrum of the dangerous point of the flexspline is proposed. By counting the rain flow of the stress spectrum,combining the modified P-S-N curve and Miner theory,the life of the flexspline of the harmonic reducer is predicted.The predicted result agrees with the life of domestic harmonic reducer products. This work will provide a reference for the quantitative evaluation of the fatigue performance of the flexspline of the harmonic reducer.
