    摘要:

    高速磁浮列车平稳性和乘坐舒适性在复杂环境下不适应已成为亟待解决的工程问题,而深入了解高速磁浮车身振动特性是合理评价舒适性指标的关键。因此,本研究通过某条高速磁浮示范线的全尺寸试验,分析列车运行过程中振动变化趋势和规律。结果表明,列车的舒适度值随着速度的增大而变差,在250km/h时舒适性最好,在430km/h时舒适性最差,其振动总值处于2级水平,且磁浮列车不同部位舒适度不同。速度小于380km/h的情况下,横向舒适度值最大;而在速度大于380km/h的情况下,则垂向舒适度值最大。

    Abstract:

    In the complex environment, the adaptability of ride comfort and stability of the high-speed maglev train has become an urgent engineering problem to be solved. In-depth understanding of the vibration characteristics of high-speed maglev body is the key to a reasonable evaluation of comfort indicators. Therefore, through the full-size test of a high-speed maglev demonstration line, this study analyzes the trend and law of vibration variation during train operation. The results show that the comfort value of the train deteriorates with the increase of the speed. The comfort value is the best at 250km/h and the worst at 430km/h. The total vibration value is at level 2, and the comfort value of the maglev train varies with different parts. When the speed is less than 380km/h, the transverse comfort value is the highest. When the speed is greater than 380km/h, the vertical comfort value is the highest.
