rail bed meaning in English
钢轨底座
Examples
- The rail beds well on the ballast .
铁轨在道碴上搁得很稳。 - 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。
