动车组制动力分配策略
|
摘要
现有动车组采用电制动和空气制动相结合的制动方式,根据实际工况和制动需求的不同采用不同的制动力分配方案。文中针对现有制动系统中车辆制动力存在故障时各单元施加制动力差距较大问题,提出一种由列车制动管理器根据各单元制动力能力值和载重比进行单元制动力分配,再由分段制动管理器在单元内按照等磨耗原则分配各车制动力的整车制动力分配策略。考虑多种工况下对制动力的需求,基于ControlBuild软件搭建动车组整车制动力分配逻辑,仿真结果表明,所提出的制动力分配策略可有效提高列车制动效率,保证列车运行安全。
Current EMU adopts combination of electrical brake and pneumatic brake.Different braking force distribution schemes are adopted according to the actual working conditions and the braking demand.In this paper,a strategy of braking force distribution is put forward for the problem of large braking force difference between units when vehicle braking force is faulty in the existing braking system.In which the train brake manager is used to distribute the unit braking force according to the unit braking force capacity and load ratio and the segment brake manager is used to distribute the braking force of each vehicle in the unit according to the principle of equal wear.The demand of braking force in various working conditions is considered.Brake force distribution logic of the EMU is built based on ControlBuild software.The simulation results show that the proposed distribution strategy of braking force can effectively improve the train braking efficiency and ensure the safe operation of the train.
