摘　　要：介绍一种适用于轨道车辆的可编程滑行故障工况速度信号模拟装置的设计,实现在实验室内模拟各种滑行相关工况,创造制动系统的滑行试验条件。通过基于emWin图形库的人机界面,设置车辆在滑行、抱死、断线和间断等故障工况的速度信号曲线,利用STM32F429微控制器模拟产生能够独立控制且具有相应故障特征的4个车轴速度信号。装置与复兴号的EBCU联机验证,实现了各种滑行工况的模拟。在实验室环境下,提供了一种对轨道和轮对无损伤的防滑控制策略研究试验方案,避免了在真实线路上人为制造滑行故障或搭建专用试验台架所存在的成本高、周期长、人力投入大的缺点。This paper introduces the design of a programmable speed signal simulator for rail vehicles in skidding conditions,which can simulate various skidding conditions in test room and generate skid test conditions for brake systems.Speed signal curves of the vehicle under fault conditions such as skidding,seizure,cable break and disconnection are set through the human-machine interface based on emWin graphics library,and the STM32F429microcontroller is used to simulate and generate four axle speed signals which can be independently controlled and correspond to fault characteristics.The linking of this device to the EBCU on Fuxing EMU proves the realization of the simulation of various skidding conditions.In test room environment,a research and test scheme of anti-skid control strategy without damage to track and wheelset is provided to avoid the disadvantages of high cost,long cycle and large manpower input in generation of artificial skidding faults or construction of dedicated test bench on real lines.
