高速列车蛇行稳定性自适应控制策略研究
Study on adaptive control strategy of hunting stability for high-speed trains
摘要
Abstract
With the extensive operation and rapid increase of high-speed trains running mileage in China,issues such as wheel-rail wear,changes in operating environments,and mismatches in suspension parameters have led to an increase in abnormal vibrations in train bodies.These issues significantly reduce the ride comfort of passengers,with insufficient bogie hunting stability being par-ticularly prominent.To address these problems,research on adaptive control strategies for hunting stability of high-speed train from the perspective of active control of yaw dampers is conducted.Firstly,yaw dampers are replaced with actively controlled sus-pension components,and a nonlinear dynamic model of the vehicle system is established.Then,an adaptive fuzzy PID controller is designed by integrating PID control principles with fuzzy control principles,and the parameters are optimized using a non-domina-ted sorting genetic algorithm with an elite strategy.Finally,based on a co-simulation model using SIMP ACK and Simulink,the control effects of the designed active control system are compared and analyzed under different operating conditions.The results show that,with the active yaw dampers,the peak amplitude of the lateral acceleration at the end of the bogie frame is reduced by up to 54％,and the Root Mean Square(RMS)value is reduced by up to 33.24％,significantly improving the lateral vibration performance of the bogie frame and providing technical support for bogie hunting stability control strategies.关键词
