摘要 以差动轮系为研究对象,分析了三个基本构件之间的转速、转矩以及功率关系,在此基础上提出了相应的灵敏度与贡献度概念并获得对应的表达式。进一步研究了灵敏度与贡献度的影响参数以及影响规律并展开了相关的对比实验。研究结果表明:转速灵敏度和转矩贡献度只与差动轮系特性参数相关;转速贡献度和功率贡献度由特性参数以及轮系转速匹配关系共同决定。灵敏度与贡献度反映了差动轮系在运动中的动态跟随性能,对差动轮系的选型与设计有参考作用。 The speed,torque and power of three DGT's basic components were analysed,and the concepts of sensitivity and contribution were studied.The parameters and rules that affected the sensitivity and the contribution were analyzed,and corresponding expressions were obtained in the end.In order to verify the speed sensitivity calculation method the tests were completed.The research results show that,sensitivity of speed and contribution torque of three basic components are only associated with the characteristic parameters of DGT,contribution expressions of speed and power are determined by the characteristic parameters and speed matching relationship of differential gear systems.Sensitivity and contribution reflect the dynamic tracking performances of DGT,and provide guidances for selection and design of DGT.
