摘要 防滑控制是高速列车制动控制中的关键技术。提高防滑控制中轮轨黏着的利用率,保障安全可靠是高速列车制动控制的核心。文章通过建立单轮对动力学模型,基于轮轨黏着特性的Polach模型对轮轨特性进行深入分析,提出单轴滑行导致全轴滑行的问题。其次,基于模糊控制算法建立控制模型,对滑移率、减速度、减速度微分3个变量进行综合考虑。最后,在Matlab/Simulink仿真平台上对其进行仿真分析。仿真结果表明:单轴滑行不及时处理会导致全轴滑行;通过基于模糊控制算法建立的控制模型,使得滑行控制的切入点选择更加精准,具有更好的防滑控制效果。 Anti-skid control is the key technology in high-speed train brake control systems.Improving the adhesion availability of wheel-rail in anti-skid control and ensuring safety and reliability is at the core of brake control systems of high-speed trains.Firstly,a dynamic model of single wheelset is established.Then according to the wheel-rail adhesion characteristics,a deep analysis based on the Polach model was made.The issue that single axle sliding causes full axle sliding was put forward.Then a control model is established based on a fuzzy control algorithm,and slip ratio,deceleration and its differential are considered comprehensively.Finally,this was verified on MATLAB/Simulink,and ideal results were achieved.The simulation results show that single axle sliding will lead to full axle sliding if it is not handled in time;the control model established based on the fuzzy control algorithm makes sliding control's entry point selection more accurate,and the anti-skid control effect is better.
