摘要
目的:为解决城市轨道交通列车进站停车后,或大坡度坡道停车后,保持制动能正常施加,却无法正常缓解而导致列车不能按时起动的问题,需研究列车保持制动的控制逻辑优化。方法:应用列车保持制动的设计原理,重点分析其施加制动力大小的原因及其施加和缓解的控制逻辑,找出在设计保持制动时的具体错误原因,并对故障列车的保持制动进行设计优化。结果及结论:提出保持制动力的大小应按照45%最大常用制动力来设计的原则,以及基于具体项目制动施加和缓解的控制逻辑方法,将保持制动缓解的逻辑从列车非零速的条件转变为列车牵引力建立超过2 s后缓解的逻辑,解决了列车在停车后保持制动的正常施加却无法正常缓解的问题。
Objective:After urban rail transit train applying normal braking during entry and parking at station or on large gradient ramp,the problem of train start-up delay due to abnormal brake release occurs,thus it is necessary to study the optimization of train brake holding control logic.Method:By analyzing the design principle of train holding brake,the reason for the magnitude of braking force applied and the control logic of braking application/release are analyzed emphatically.The specific errors during design that cause brake holding are identified,and the design optimization of faulty train brake holding is conducted.Result&Conclusion:Design principle of setting brake holding force at 45%of maximum full service braking force is proposed,as well as the logic control method of braking application/release according to specific projects.The logic of releasing the held brake is changed from the condition of train non-zero speed to 2 seconds after train traction establishment,solving the problem of train abnormal brake release after normal parking braking application.
