伴随着运行速度的提升和轮轨磨耗的加剧，轮轨蠕滑效应势必增大，高速列车面临的转向架蛇行运动稳定性挑战更为严峻。传统悬挂参数无法随轮轨关系变化而调整，主动控制则成为潜在的解决办法。然而，目前转向架稳定性控制局限于对轮对或转向架运动状态的主动质量、刚度或阻尼调节，尚未取得很好的进展。为此，本项目提出基于轮轨纵向蠕滑率的反馈控制方法，将轴箱转臂替换为机电作动器，利用作动力减小或消除摇头蠕滑力矩。首先，通过理论分析，探讨轮轨蠕滑率对蛇行运动的负阻尼反馈机制，研究增益和时滞对转向架蛇行运动分岔特性的影响规律。其次，构建理想控制目标表达式，建立控制系统传递函数模型，研究实时前馈时滞补偿算法和自抗扰误差估计补偿算法。最后，开展高速列车机电耦合系统动力学仿真和台架稳定性试验研究，以验证理论研究。通过本项目实施，有望提升高速转向架蛇行运动稳定性，延长轮轨型面镟修周期，为下一代高速列车研制提供理论支撑。

With the increase of running speed and the aggravation of wheel-rail wear, the wheel-rail creep effect will be inevitably increased, and the bogie hunting stability challenges of high-speed trains will be more crucial. The traditional suspension parameters cannot be adjusted with the change of wheel-rail relations, thus the active control may become a potential solution. However, the active stability control at present is limited to the adjustment of wheelset or bogie motion states by the active mass, stiffness or damping approaches and has not maken too much progress. Therefore, this project tries to propose a feedback control approach based on the wheel-rail longitudinal creepage. By replacing the axle box guiding arm with an electromechanical actuator, the wheelset yaw creep moment can be reduced or eliminated by the actuating forces. Firstly, the negative damping feedback mechanism of wheel-rail creepage on hunting motion is discussed by theoretical analyses. The effects of feedback gain and time delay on the hunting bifurcation characteristics of the bogie are studied. Secondly, the expression of the ideal control objective is derived, and the transfer functions of the control system are constructed. The real-time algorithms for feedforward delay compensation and ADRC error estimation are studied. Finally, the numerical simulations of the electromechanical coupling dynamics of high speed bogies and stability tests on roller rig are carried out to verify the effectiveness of theoretical studies. Based on the implementation of this project, it is expected to improve the hunting stability of high-speed bogies, extend the wheel and rail re-profiling periods, as well as provide theoretical support for the development of the next generation of 400km/h high-speed trains.
