摘要:
结合高速动车组车载转向架失稳报警装置在应用中的实际问题，针对车辆第一次失稳报警后的限速时间及加速度传感器的布置方案进行深入探讨。根据实测数据及相关标准，在保证车辆运行安全的基础上，以最大限度保证运营秩序为原则，当车辆首次出现报警限速值200 km/h时，建议限速保持时间不小于106 s。通过构架不同端部实测振动数据以及构架受力分析，对于单转向架，由于前后轮对蛇行运动存在相位差，非导向轴上方构架端部受到导向轴力的叠加影响，横向振动加速度幅值一直大于导向轴构架端部，因此建议传感器布置在1、4轴或2、3轴构架端部。
Abstracts:
Combined with the practical application problems of on-board bogie instability alarm device in high-speed EMU trains, the speed limit time after the first instability alarm and the layout scheme of acceleration sensors are discussed in depth. According to the measured data and relevant standards, and in the principle of maximizing the operation order to ensure the train safe operation, the speed limit holding time is recommended no less than 106 s when the first alarm speed limit value is about 200 km/h. Through the measured vibration data of different frame ends and the frame stress analysis, due to the phase difference between the front and the rear wheel sets hunting of the single bogie, the lateral vibration acceleration amplitude of the frame end above the non-steered wheel sets is always greater than the frame end above the steered wheel sets, which is influenced by the superposition effect of the axial force, so it is recommended that the sensors should be arranged on the frame ends above the 1,4-axles or the 2,3-axles.
