摘要:
对快速地铁车辆可能产生的空气动力效应进行了描述,并详细分析了与气动效应相关的车辆设计参数及其变化规律。分析表明,随着车速的提高、车辆断面积的增大,列车空气阻力、压力波幅值、气动噪声等均有不同程度的增大;列车头型长细比越大、车辆表面平顺程度越高,列车空气阻力越小。
Abstracts:
Regarding rapid metro vehicle, the possible aerodynamic effects are described, vehicle design parameters related to aerodynamic effect and their change rules are analyzed in detail. The research shows that with the increase of vehicle speed and cross section, the aerodynamic resistance, amplitude of pressure wave and aerodynamic noise will also increase to varying degrees. Besides, the greater increase of vehiclehead slenderness ratio and carbody surface smoothness, the smaller aerodynamic resistance will be.
