利用虚拟样机技术研究了影响旋转矢量减速器动态传动误差的因素，包括弹性变形、工作载荷、零件制造误差和装配间隙。根据RV减速器的误差传递关系，选取15个影响因素设计了正交仿真试验。利用CREO和Ansys建立了RV减速器的虚拟样机，并导入ADAMS中进行多体动力学仿真。通过实验验证了仿真方法的可靠性。结果表明，销齿圆心半径误差、摆线齿轮等距变位量、摆线轮径向变位量、支承套与行星架间隙、曲轴与支承套间隙与RV减速器动态传动误差呈正相关。其中，销齿圆心半径误差对RV减速器动态传动误差的影响最大，其次是摆线齿轮等距修形量。零件的弹性变形和载荷波动对传动误差表现出一定的增益效应，摆线轮的弹性变形影响较大，销齿的弹性变形最小。
The factors influencing rotate vector (RV) reducer dynamic transmission error were studied using virtual prototyping technology, which contained the elastic deformation, working load, part manufacturing error, and assembly clearance. According to the error transmission relationship of the RV reducer, 15 influencing factors were selected to design an orthogonal simulation test. The virtual prototype of the RV reducer was built using CREO and ANSYS, and imported into ADAMS for multi-body dynamics simulation. The simulation method reliability was verified via experiments. The results show that the circle center radius error of the pin gear, the amount of equidistant modification of the cycloid gear, the amount of radial-moving modification of the cycloid gear, the clearance between the support bushing and planet carrier, and the clearance between the crankshaft and the support bushing were positively correlated with the RV reducer dynamic transmission error. Among these, the circle center radius error of the pin gear has the greatest influence on the dynamic transmission error of the RV reducer followed by the amount of equidistant modification of the cycloid gear. The elastic deformation of the part and the load fluctuation show a certain gain effect on the transmission error, the elastic deformation of the cycloid gear has a great influence, and the elastic deformation of the pin gear has the least.
