自从C.W.Musser发明了谐波齿轮减速器并运用到火箭上后，由于它的传动比大、重量轻、可靠度强、体积小、传动精度高等优点而倍受关注。我国从两弹一星开始，在大力发展航天事业的背景下，谐波齿轮减速器被广泛地运用到火箭及卫星的传动机构中。但国内对于谐波齿轮减速器的失效机理和结构优化及多样化等方面还需深入研究，尤其缺乏对其动态运转强度较为精确的计算和对其疲劳寿命的评估。 针对上述问题，本文研究谐波齿轮减速器的强度与失效机理，给出了一种基于应力-寿命法的疲劳预测过程，并对谐波减速器的结构进行了改进。主要的研究内容包括： （1）设计了谐波齿轮减速器结构，并运用SolidWorks建立了3D模型。其中...Since harmonic gear reducer designed by C. W. Musser had been applied into rocket, it has got continuous attention for its advantages in big transmission ratio, light weight, strong reliability, small volume, high drive accuracy and so on. Since the advent of two Bombs and one Satellite of our country, with the development of aerospace industry, harmonic gear reducer is widely applied into the tra...学位：工学硕士院系专业：航空航天学院_工程硕士(机械工程)学号：3202014115286
