振弦式表面應(yīng)變計：是表面應(yīng)變計的一種類型，它采用振弦這種彈性材料作為傳感器元件，通過弦的振動來測量物體表面的應(yīng)變.通常由振弦、電纜、信號調(diào)節(jié)器等組成。振弦是一種薄的彈性金屬絲，通常由銅、硬合金或鎢等材料制成。當(dāng)物體表面受到應(yīng)變時，振弦發(fā)生彎曲和扭轉(zhuǎn)等形變，從而影響其震動狀態(tài)。電纜連接振弦和信號調(diào)節(jié)器，并將振弦的振動信號傳輸?shù)叫盘栒{(diào)節(jié)器中。信號調(diào)節(jié)器對信號進(jìn)行放大、濾波和轉(zhuǎn)換等處理，得到表面應(yīng)
表面應(yīng)變計：是一種用于測量材料或結(jié)構(gòu)表面的應(yīng)變(變形)的傳感器。它可地測量材料或結(jié)構(gòu)表面受力后的應(yīng)變變化，以評估其在受載情況下的性能和安全性。通常由應(yīng)變片、應(yīng)變導(dǎo)線和信號調(diào)節(jié)器組成。應(yīng)變片是一種非常薄的傳感器，可以附著在測量目標(biāo)表面，例如金屬、混凝土等。應(yīng)變感應(yīng)片的形狀和材質(zhì)會隨著具體的應(yīng)用而有所不同。
