摘要
为对弓网载流摩擦力进行建模研究,通过实验研究摩擦力与压力波动频率、压力波动幅度、接触电流、滑动速度的关系,建立了摩擦力的LuGre静态模型,利用麦夸特法和通用全局优化法对模型中的静态参数进行辨识;在已建立的LuGre静态模型的基础上,通过引入动态参数,建立了摩擦力的LuGre动态模型,利用遗传算法结合Simulink仿真的方法对模型中的动态参数进行辨识.研究结果表明:动态模型更具有有效性,为弓网摩擦力的预测及摩擦磨损性能的研究提供参考.
In order to model the friction of the current-carrying pantograph-catenary system,the LuGre static friction model was established by experimental research the relationship between friction force and pressure fluctuation frequency,pressure fluctuation amplitude,contact current,and sliding speed.The static parameters in the model were identified by using the McQuad method and the general global optimization method.Based on the established LuGre static friction model,by introducing dynamic parameters,the LuGre dynamic friction model was established.The dynamic parameters in the model were identified by combining Genetic algorithm with Simulink simulation.The outputs of model verifying the dynamic model with more effective,which provides a reference for the frictional prediction and frictional wear properties of pantograph-catenary system.
