摘要
动力集中型动车组制动系统采用列车管和总风管双管供风方式.在制动系统副风缸与总风管之间有一个单向阀和节流孔,用于在动车组总风管故障时给生活风缸供风,使车载用风设备能够正常工作.文章建立了动车组车辆制动供风系统模型,故障工况下隔离动力车总风管时,主要用风设备——卫生间设备连续工作时,节流孔孔径对制动系统性能的影响进行了仿真分析.仿真结果表明,在总风管故障工况下,关闭车辆内部一个卫生间,合适的节流孔孔径设置可以保证不影响制动系统性能的前提下,使其余车载设备也能够正常使用,保证旅行中的舒适性.文章为发生总风管故障隔离时列车继续运行提出了一种应对方案.
Abstract
The brake system of power centralized EMU adopts the dual-pipe air supply mode with train pipe and blast main.There is a one-way valve and an orifice between the auxiliary reservoir of the brake system and the blast main to supply air to the domestic reservoir when the blast main of the motor car fails,so that the vehicle-borne air consuming equipment can work normally.The article builds a model for the brake air supply system of EMU which can simulate the main air consuming equipment(the sanitary equipment)to continue the operation when the blast main of the motor car is isolated in case of fault and make the simulation analysis of the effect of the orifice diameter on the performance of brake system.The simulation result show:when the blast main fails,closing a toilet in the car,an appropriate orifice diameter can ensure the normal operation of the remaining vehicle-borne equipment without affecting the performance of brake system to guarantee the ride comfort.The article proposes a solution allowing the train to continue its operation when the blast main is isolated in case of fault.
