【摘要】：近年来我国铁路事业迅速发展,运行里程和运行时速均不断提高。同时,列车运行时面临的安全性问题也更加严峻,其中就包括转向架蛇行失稳现象。列车在平直轨道上行驶时会产生蛇行运动,当这种蛇行运动的幅值超过一定阈值时会产生蛇行失稳现象。蛇行失稳会增大转向架的横向振动,导致列车运行不平稳,还会增大列车机械部件的磨损,甚至会造成列车脱轨,对列车运行安全产生严重的威胁。因此,要确保列车运行的安全性就需要控制蛇行运动的幅值。通过实时监测系统可以在蛇行运动幅值过大时发出报警信息,提醒司机采取措施,进而保证列车运行安全性。转向架失稳检测装置实时监测列车转向架振动状态,确保列车运行安全。该产品投入使用后将会处于复杂的电磁环境下,容易受到各类电磁骚扰,同时可能对列车上其他设备产生干扰。所以需要对产品的电磁兼容特性展开研究,保证产品在电磁干扰中能维持预定功能。本文阐述了电磁兼容的基本理论,分析了产品使用过程中可能遇到的干扰。针对不同的干扰,对产品的不同端口采取了相应的解决措施,优化了产品的电磁兼容特性。产品设计完成后,按照铁路交通设备电磁兼容特性标准(GB/T24338.1-2009)要求进行了电磁骚扰和电磁抗扰度试验。各项试验过程中产品均能正常完成相关功能,满足标准中的相关要求,顺利通过测试。
[Abstract]:In recent years, China's railway industry has developed rapidly, running mileage and speed are constantly improving.At the same time, the safety problem of train running is more serious, including bogie snake instability.When the train travels on a straight track, a snake motion will occur, and when the amplitude of the snake motion exceeds a certain threshold, the phenomenon of snake instability will occur.The instability of snake will increase the lateral vibration of bogies, cause the train running unsteady, increase the wear and tear of train mechanical parts, even cause train derailment, and pose a serious threat to the safety of train operation.Therefore, to ensure the safety of the train, we need to control the amplitude of snake motion.The real-time monitoring system can send out alarm information when the amplitude of snake movement is too large, and remind the driver to take measures to ensure the safety of train operation.The bogie instability detection device monitors the vibration state of the bogie in real time to ensure the safety of train operation.When put into use, the product will be in a complex electromagnetic environment, vulnerable to all kinds of electromagnetic disturbance, and may interfere with other equipment on the train.Therefore, it is necessary to study the electromagnetic compatibility characteristics of the product to ensure that the product can maintain its predefined function in EMI.Aiming at the different interference, the corresponding measures are taken to solve the different ports of the products, and the electromagnetic compatibility characteristics of the products are optimized.After the product design was completed, the electromagnetic disturbance and electromagnetic immunity tests were carried out according to the standard GB / T 24338.1-2009 of electromagnetic compatibility characteristics of railway transportation equipment.The products can complete the related functions normally and meet the relevant requirements in the standard and pass the test smoothly.
