| 摘 要： | 基于多尺度法及Fourier级数展开，对不同运动规律下的单自由度周期时变凸轮系统的稳定性进行了分析，给定了系统的稳定区域图。结果表明相同的时间分配、不同的运动规律对系统稳定性的影响甚小，而不同的时间分配、相同的运动规律对系统稳定性的影响很大。

| Abstract: | Dynamic stability of periodically time-varying cam system of SDOF is investigated based on the combination of both the method of multiple scales and Fourier series expansion.The corresponding stability charts are given for different cam profiles and cam motion event types. Results show that the motion event types with the same cam profile dominate the stability of the cam systems and the cam profiles with the same motion event type influence it very little. |

| Keywords: | periodically time-varying system cam system stability method of multiple scales |
