摘　　要：换挡机构是变速系统中最关键的部件之一,其性能直接影响传动系统的动力性和平稳性。建立了二级换挡行星传动系统动力学方程,研究了外界激励频率对传动系统复杂动力学特性的影响;通过分析分岔图、时域响应图、相图、庞加莱截面图以及频谱图变化规律,明晰了二级换挡行星传动系统混沌振动特性,获得了外界激励频率稳定振动区间;利用比例微分控制方法对传动系统混沌振动进行控制,将混沌振动调整为稳定的单周期振动。研究结果为提高换挡行星传动系统运转的稳定性奠定了基础。Gear shifting mechanism is one of the most critical components in the shifting transmission system,and its performance directly affects the power performance and stability of the transmission system.In this study,the dynamic equations of the gear shifting mechanism of the two-stage planetary gear transmission system are established,and the influence of the external excitation frequency on the complex dynamic characteristics of the transmission system is studied.Through bifurcation diagram,time domain response diagram,phase diagram,Poincare section diagram and spectrum diagram,the chaotic vibration characteristics of the two-stage planetary gear transmission system are learned,and the stable vibration range of the external excitation frequency is obtained.The proportional differential control method is used to control the chaotic vibration of the gear shifting mechanism,and the chaotic vibration is adjusted to a stable single period vibration.The research results lay a foundation for improving the stability of the shift planetary transmission system.
