vibration-frequency measurement

基本解釋

So the ultra-low frequency absolute vibration detection is a difficult problem in engineering measurement field.
因此超低頻絕對振動(dòng)檢測一直是工程測試領(lǐng)域的一大難題。
The low frequency, weak mechanical vibration experiments show that detection system can realize the non-contact measurement.
微弱機(jī)械振動(dòng)信號(hào)的探測結(jié)果表明，該系統(tǒng)能實(shí)現(xiàn)無接觸測量。
Described in this paper is a newly developed portable computer-based vibration frequency measurement system for turbine blades.
採用以便攜式計(jì)算機(jī)爲(wèi)核心的新型汽輪機(jī)葉片頻率測量系統(tǒng)可大大提高測量的精確度和工作傚率。

high -frequency vibration measurement 高頻測振
low -frequency vibration measurement 低頻振動(dòng)測量
free coupled -vibration force-measurement frequency-domain method 自由耦郃振動(dòng)測力頻域法
super low -frequency vibration measurement 超低頻振動(dòng)測量
