rail vibration meaning in English
钢轨振动
Examples
- Noise radiated by the rail vibration is considered to be the main portion of wheel / rail noise in the frequencies blew 3000hz
研究表明, 3000hz以下的轮轨噪声中由钢轨振动产生的辐射噪声占轮轨噪声的70 %以上。 - Actual measurement indicates that the displacement and acceleration of rail vibration both have random property , the displacement spectrum mostly has obvious low frequency contets which occupy dominant peak value range
实测表明,轨道振动的位移和加速度都具有随机特性,位移频谱组成以低阶频率为主,且有明显占优势的峰值区域。
