通过论述国内外机器人减速器性能检测技术研究现状，对比了与国外的差距，分析了机器人用谐波减速器和机器人用精密齿轮传动装置标准方法差异。选取机器人用谐波和RV减速器，对精密减速器的扭转刚度、传动效率两个关键性能指标的测试方法进行探讨，并对其测试方法进行了验证。通过探讨，结论是现行国标对机器人精密减速器的性能测试方法的规定不统一，机器人用精密减速器的扭转刚度和传动效率值都与角位移和转矩这两个基本参数相关，测量设备本身的精度和设计方法影响测量结果，设备标准化、集成化、智能化方面仍有较大发展空间。 相似文献

The numerical calculation method is widely used in the evaluation of slope stability,but it cannot take the randomness and fuzziness into account that exist in rock and soil engineering objectively.The fuzzy optimization theory is thus introduced to the evaluation of slope stability by this paper and a method of fuzzy optimal selection of similar slopes is put forward to analyze slope stability.By comparing the relative membership degrees that the evaluated object sample of slope is similar to the source samples of which the stabilities are detected clearly,the source sample with the maximal relative membership degree will be chosen as the best similar one to the object sample,and the stability of the object sample can be evaluated by that of the best similar source sample.In the process many uncertain influential factors are considered and characteristics and knowledge of the source samples are obtained.The practical calculation indicates that it can achieve good results to evaluate slope stability by using this method. 相似文献
