Influence of Underbody Parameters of High-Speed Trains on Aerodynamic Noise

  • 摘要:

    为更好地开展高速列车气动降噪设计,建立了高速列车头车第一组转向架区域的6参数模型,采用计算气动声学和拉丁超立方抽样实验所设计的方法,得到了13个参数化模型的远场气动噪声、转向架舱内湍流脉动功率级和声功率级,并分析了底部结构参数对远场和近场气动噪声的影响规律. 结果表明:底部结构参数对远场噪声影响范围为75.4~78.9 dB(A),裙板高度、排障器厚度、转向架舱后缘倒角和舱长度与远场噪声为负相关,舱前缘倒角、排障器前缘夹角与远场噪声为正相关,底部结构参数的变化主要影响中心频带315~1250 Hz间的噪声能量;排障器厚度和前缘夹角与远场噪声、舱内湍流脉动功率、声功率均为负相关;裙板高度和远场噪声、舱内湍流脉动功率级为负相关,与舱内声功率为正相关.
