摘要
为抑制列车垂向振动提高其运行平稳性,建立基于超磁致伸缩作动器系统的高速列车主动悬挂半车六自由度模型,轨道线路激励选择德国低激扰轨道谱。对超磁致伸缩作动器系统动力学建模,求解输出做动力与输出位移、输入电流的关系。通过设计模糊控制器和模糊PID控制器,利用Matlab2019b/Simulink仿真得出主动悬挂垂向加速度和前、后构架作动力的范围曲线。参照列车平稳性指标计算标准,求解验证得出基于超磁致伸缩作动器系统的主动悬挂模糊PID控制的减振效果,优于被动控制和模糊控制。
In order to suppress the vertical vibration of the train and improve its running stability,a six-degree-offreedom model for the active suspension of a high-speed train based on the giant magnetostrictive actuator(GMA)system was established.The track line excitation was selected from the German low-disturbance track spectrum.Model the dynamics of the giant magnetostrictive actuator system,and solve the relationship between output power and output displacement and input current.Through designing fuzzy controller and fuzzy PID controller,using Matlab2019b/Simulink simulation to obtain the active suspension vertical acceleration and front and rear frame power range curves.With reference to the train stability index calculation standard,the solution and verification show that the vibration reduction effect of the active suspension fuzzy PID control based on the giant magnetostrictive actuator system is better than the passive control and the fuzzy control.
