|resonance vibration/syntony;共振
sympathetic vibration(共振振動)是物理學中的一種現象,指當某一物體因外界作用産生振動時,若其振動頻率與另一物體的固有頻率相同或接近,後者會因能量傳遞而自發産生振動。這種現象本質上是共振的一種表現形式,常見于機械系統、聲學及電磁學領域。
從原理分析,sympathetic vibration的發生需滿足兩個核心條件:
在工程應用中,sympathetic vibration既有積極作用,也可能帶來風險:

“Sympathetic vibration”(交感振動/共振)是物理學中的術語,指當一個物體受到外界振動頻率與其固有頻率一緻時,産生的共振現象。以下是詳細解釋:
定義與原理
當某一系統(如琴弦、橋梁)的固有頻率與外部振動源的頻率相匹配時,系統會吸收能量并放大振動幅度,這種現象稱為“sympathetic vibration”。其本質是能量通過頻率匹配的共振傳遞。

應用與示例
與普通振動的區别
普通振動需持續外力作用,而交感振動一旦觸發,可在無直接接觸下持續(如音叉間的振動傳遞)。
總結來看,這一術語結合了“sympathetic”在物理學中“共鳴”的含義(而非日常的“同情”義),強調頻率匹配引發的能量響應。
