摘要

针对静态气密参数无法真实反映动车组过隧道时的气密性能问题和车内压力舒适性问题。基于一维可压缩不等熵非定常流动模型的广义黎曼变量特征线法，数值模拟车外压力；建立了高速列车通过隧道时模拟车内压力波的“当量泄漏面积”法。以京沪客运专线为背景，研究了中国某型号标准动车组的动态当量泄漏面积阈值随动车组编组长度、速度和是否交会的变化规律；给出了动车组在不同速度等级下符合不同舒适性标准时单节车厢动态当量泄漏面积建议值。研究表明：动车组的当量泄漏面积阈值的最小值随着车速的增加而减小；头/尾车和中间车最严格的当量泄漏面积建议值分别为10.3 cm2和18.9 cm2，为高速动车组气密性设计及优化各部件气密性能提供基础性技术参考。

Abstract

Aiming at problems of static air tightness parameters being not able to truly reflect air tightness performance and inside pressure comfort of EMU when passing through tunnels, based on the 1-D compressible non-isentropic unsteady flow model, the generalized Riemannian variable characteristic line method was used to simulate pressure outside train, and the equivalent leakage area method was established to simulate the pressure wave inside train when a high-speed train passing through tunnels. Based on the background of Beijing-Shanghai passenger dedicated line, the varying laws of dynamic equivalent leakage area threshold of a certain type of standard EMU in China with variation of EMU formation length, speed and meeting or not of EMUs were studied, and recommended values of dynamic equivalent leakage area of a single car when EMU meeting different comfort standards at different speed levels were given. Results showed that the minimum value of the equivalent leakage area threshold of EMU decreases with increase in train speed; the most stringent equivalent leakage area recommended values of head/tail car and intermediate car are 10.3 cm2 and 18.9 cm2, respectively to provide a basic technical reference for air tightness design and optimization of each component of high-speed EMU.
