甚麼是【實驗模態分析】？
What is “Experimental Modal Analysis” (EMA)?
【實驗模態分析】(Experimental Modal Analysis, EMA)
也可稱為【模態試驗】(modal testing)。
【實驗模態分析】是一種實驗方法，主要在求得結構的模態參數，包括：自然頻率、模態振型及模態阻尼比。
【實驗模態分析】的基本步驟：(1)量測取得結構的頻率響應函數。(2)由頻率響應函數透過曲線嵌合求得模態參數。

Modal Analysis (EMA) is also known as “Modal Testing.”
EMA is the
experimental method to obtain structural modal parameters, including Natural
frequencies, Mode shapes and Modal damping...
