| 摘 要： | 采用1/4车模型分别对两种半主动控制策略即SH（Sky-hook, SH）和ADD(Acceleration Driven Damping, ADD)控制进行分析，根据分析结果引入了一种新型SH-ADD混合控制策略。利用随机激励下的功率谱密度曲线代替单频谐波激励下的传递函数曲线，改进了该混合控制策略转换系数的计算方法。在采用ADAMS软件建立高速铁道车辆整车模型的基础上，对改进后的SH-ADD控制策略进行了仿真分析。仿真结果表明，该控制策略可以同时兼顾低频和中高频率范围内的振动控制效果，较SH控制和ADD控制可大幅提高车辆的横向平稳性能。

| Abstract: | In order to study a simple and easy to realize semi-active control strategies, Sky-hook(SH) control and Acceleration Driven Damping(ADD) control are analyzed by using the 1/4 car model. According to the analysis results, a mixed SH-ADD control strategy is introduced. Through replacing the transfer function curves under single frequency harmonic excitation by power spectral density curves under random excitation, calculating method of conversion factor is improved in the thesis. On the base of building whole model of high-speed railway vehicle, the modified SH-ADD control strategy is simulated and analyzed. The simulation results show that the new mixed control strategy can has good performance of vibration control in both low and middle-high frequency range, which lateral running performance is better than SH and ADD. |
