钢轨振动 meaning in English

rail vibration

Fem analysis on cwr vibration characteristic through harmonic response way
无缝线路钢轨振动特性谐响应有限元分析
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。
Testing the vibration acceleration signal of rail top ( lateral and vertical ) , rail middle ( lateral ) , rail bed side ( vertical ) and rail bed middle ( vertical ) with dasp vibration testing system , calculation of signals obtains the power spectral density and frequency response curves of different position
测试横向和垂向激振力下钢轨不同部位的振动信号,进行频谱分析,得出不同部位的频率响应曲线。通过对频响曲线的分析,得出不同方向激振力下钢轨振动能量集中的频率,确定不同方向激振力下钢轨的主要振动部位和振动形式。
