| 摘 要： | 为了抑制由高速车体摇头引起的车体横向振动,构造了高速列车横向半主动悬挂系统模糊控制结构,采用模糊控制策略,以减振器的实际阻尼力和车体、构架的横向振动加速度为反馈输入,对车体前后横向悬挂系统的可调减振器进行双闭环反馈独立控制.以美国六级轨道谱为输入,在列车运行速度为270 km·h-1时,结合表征列车悬挂系统横向振动特征的17自由度动力学模型,对半主动悬挂机车和被动悬挂机车的横向振动、摇头振动进行计算.计算结果表明:采用半主动悬挂的高速车体平稳性改善了12.54%,摇头振动幅值减少了35.00%,横向振动幅值减少了48.45%,在车体固有频率(1～6 Hz)附近,车体横向振动、摇头振动抑制达到50%.可见,该控制结构和控制策略能够明显抑制车体横向振动.

| Abstract: | In order to reduce the lateral vibration of high-speed train caused by shaking movement, a fuzzy control structure of lateral semi-active suspension system was designed. Fuzzy control strategy was adopted to independently control the adjustable shock absorber of suspension system based on double-loop feedback inputs, which were the actual damping force of the shock absorber and the lateral vibration accelerations of the frame and the body for train. With the 17 DOFs vehicle dynamics model that can reflect t... |
