1.
Based on this,in order to take more detailed demonstration or evaluation for the rolling noise under the high speed condition,according to the relationship between effective roughness,which derived from indirect measurement of combined effective roughness through vertical vibration of rail,and sound pressure,the transfer function for effective roughness to sound pressure was deduced.
为了对高速运营条件下的轮轨滚动噪声进行更详细描述和评价,通过对钢轨竖向振动的测量,间接得到轮轨有效不平顺度,再结合声压测量结果,根据有效不平顺度与声压间的简单关系得到不平顺度对声压的转换函数,合成有效不平顺度与转换函数的组合可用于任何列车速度、任何给定列车轨道系统的噪声辐射谱预测;将车辆噪声和轨道噪声分开进行评估量化,为从车辆与轨道两方面寻求有效控制和降低轮轨噪声的方法奠定基础。
