正弦振動可以描述為確定性運動，遵循確定的規(guī)律，完全可以從過去的狀態(tài)來確定未來任意指定時間的狀態(tài)。在進行正弦掃頻試驗過程中，改方法通常用來確定出現(xiàn)失效的時刻，因為這個失效很可能是和特定頻率密切相關(guān)的，而用隨機振動試驗試驗方法這種相關(guān)效果不是很明顯。當然，相對于隨機試驗方法，正弦試驗方法通常需要用更長的時間激發(fā)出失效，這是因為每次掃頻過程中，在每個共振點上只作用很短的時間。盡管在任一時刻只施加一個頻率，如果掃頻速率足夠慢，確實可以使得樣品的特定共振峰達到較大，上海電路板**振動臺廠家。也可以用來發(fā)現(xiàn)潛在的破壞性共振點，上海電路板**振動臺廠家，上海電路板**振動臺廠家，尤其是在設(shè)計和研制試驗中。正弦振動試驗的另一個用途是在兩種頻率上的駐留試驗：1、已知的強迫頻率；2、樣品的諧振頻率。液壓式振動臺是把液壓能轉(zhuǎn)換成動能。上海電路板**振動臺廠家</p><div

1、接通系統(tǒng)電源確定增益開關(guān)處于復(fù)位位置再合上功放漏電斷路的開關(guān)。 2、按試驗說明書的要求正確設(shè)置試驗參數(shù)并保存，調(diào)用試驗數(shù)據(jù)和檢查試驗設(shè)置要和說明書一致。 3、按下電源通按鈕風(fēng)機啟動后。打開增益旋鈕至合適位置(參照使用說明書)/此時“準備”“啟動”“電源”燈亮，系統(tǒng)進入待運行狀態(tài)。 4、進行試驗，隨時記錄試件狀態(tài)和試驗設(shè)備狀態(tài)，保存相應(yīng)試驗數(shù)據(jù)。</p><p style="text-indent:25px">振動臺又稱振動激勵器或振動發(fā)生器。它是一種利用電動、電液壓、壓電或其他原理獲得機械振動的裝置。其原理是將激勵信號輸入一個置于磁場中的線圈，來驅(qū)動和線圈相聯(lián)的工作臺。電動式振動臺主要用于10Hz以上的振動測量，較大可激發(fā)200N的壓力。在20Hz以下的頻率范圍，常使用電液壓式振動臺，這時振勸信號的性質(zhì)由電伺服系統(tǒng)控制。液壓驅(qū)動系統(tǒng)可以給出較大的位移和沖擊力。振動臺可以用于加速度計的校準，也可用于電聲器件的振動性能測和其聳的振動試驗。對于不同的測試物和技術(shù)指標，應(yīng)注意選用不同結(jié)構(gòu)和激勵范圍的振動臺。振動臺特點：移動式工作基架，易于放置，美觀大方。</p><div
