模型三要素

模型(xing)是(shi)通過建模語(yu)言、表示法和文(wen)字描述來表示的。語(yu)法（syntax）、語(yu)義(yi)（semantics）和語(yu)用（pragmatics）是(shi)模型(xing)的三個(ge)要素。

語法是使用建模語言(yan)所提供的元素(su)的方法，以(yi)及如何(he)組織、關聯(lian)這(zhe)些元素(su)。

語義是指一個(ge)具體模型所表達(da)的(de)含義。

語用則表示模型在特定環境下的應用，以及應用此模型的環境對模型本身的影響。

機械振動的動力學模型是什么

機械振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)有(you)不同的(de)分(fen)類方(fang)法。按(an)產生振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)原因可(ke)(ke)分(fen)為(wei)(wei)自由振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)、受迫(po)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)和自激振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong);按(an)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)規律可(ke)(ke)分(fen)為(wei)(wei)簡(jian)諧振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)、非諧周期振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)和隨(sui)機振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong);按(an)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)系統結構參數的(de)特性(xing)可(ke)(ke)分(fen)為(wei)(wei)線(xian)性(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)和非線(xian)性(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong);按(an)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)位移(yi)的(de)特征(zheng)可(ke)(ke)分(fen)為(wei)(wei)扭轉振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)和直(zhi)線(xian)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)。就是把真實(shi)機器(qi)按(an)照一(yi)定比例(li)做出來，以及外觀(guan)動(dong)(dong)(dong)(dong)(dong)(dong)態效果的(de)一(yi)種模仿。

受迫振動

自激振動

在(zai)非線性(xing)振動(dong)中，系統(tong)只受其本(ben)身產(chan)生的(de)激勵所維持(chi)的(de)振動(dong)。自激振動(dong)系統(tong)本(ben)身除(chu)具有振動(dong)元件外，還具有非振蕩性(xing)的(de)能源(yuan)、調節(jie)環(huan)節(jie)和反饋環(huan)節(jie)。
