free vibration mode

基本解釋

This paper focuses on free-interface component mode synthesis methods for damped vibration systems.
研究了阻尼振動系統(tǒng)的自由界面子結(jié)構(gòu)綜合法。
The damping properties in the free vibration of the system were extracted by complex-mode analysis technique.
通過復(fù)模態(tài)分析得到以超越方程形式表達(dá)的系統(tǒng)自由振動阻尼特性的解析形式。
Processing the response signals by using the random decrement technique, a unique corresponding to each mode is obtained, which represents a free vibration response of the structure.
應(yīng)用隨機(jī)減量技術(shù)對響應(yīng)信息進(jìn)行處理，相應(yīng)于結(jié)構(gòu)的每一振型可得到一條獨(dú)特的隨機(jī)衰減曲線，該曲線代表結(jié)構(gòu)自由振動響應(yīng)。

Lens-shift Vibration Reduction (VR) alongside the new Active Mode assist in capturing blur-free images and video, while full manual controls give users the power to realize their creative potential when shooting.
