Abstract

Abstract The paper focuses on the experimental verification of the results derived from numerical simulations, based on a model of the bogie-track system, where the vertical track irregularities are introduced in the form of a pseudorandom function. This function comes from an original method of synthesizing the vertical track irregularities, depending on the geometric quality of the track and on the velocity. To verify the method, the root mean square (RMS) of the simulated accelerations in the axles and the bogie frame against each axle is compared to the experimental accelerations within the frequency range of wavelengths of the track vertical irregularities from 3 to 120 m. The results have shown a good correlation between the simulated RMS accelerations for a low quality track and the measured RMS accelerations.

轨道垂直不规则度综合方法的实验验证
摘要本文以转向架轨道系统模型为基础,以伪随机函数的形式引入了垂直轨道的不规则性,重点对数值模拟结果进行了实验验证。该函数来自于合成垂直轨迹不规则性的原始方法,这取决于轨迹的几何质量和速度。为了验证该方法,将车轴和转向架构架相对于每根车轴的模拟加速度的均方根(RMS)与轨道垂直不规则性波长范围(3至120m)内的实验加速度进行比较。结果表明,低质量轨道的模拟RMS加速度与测量的RMS加速度之间具有良好的相关性。
