振動試驗臺是用于在實驗室內(nèi)模擬真實振動環(huán)境效應(yīng)的試驗設(shè)備，振動試驗是在振動臺上采用不同的輸入信號激勵樣品。振動試驗主要分為正弦和隨機振動，由于兩者的物理過程不同，在兩者之間沒有嚴格的等效關(guān)系，所以在選擇試驗方式時，切勿進行正弦到隨機的嚴酷度等級轉(zhuǎn)換。在使用振動試驗臺的過程中，為了保證設(shè)備的穩(wěn)定性以及高效性，有三個環(huán)節(jié)是及其關(guān)鍵的，那就是安裝、使用以及保養(yǎng)，只有這三步同時進行，方能保證設(shè)備的穩(wěn)定性，對于設(shè)備的使用壽命也是很好的延長作用，湖南小型振動試驗臺生產(chǎn)廠家。簡述振動試驗臺的安裝事宜以及要求：振動試驗臺安裝場地一定要平穩(wěn)，因為做振動試驗，所以設(shè)備開始工作的時候振動會很強烈，地面不平整會影響振動試驗的精確度，湖南小型振動試驗臺生產(chǎn)廠家，不平穩(wěn)的工作環(huán)境還容易產(chǎn)生噪聲、損壞設(shè)備。接著把振動臺體的輸入線接到控制箱的輸出孔里（垂直輸入孔接15厘米的臺面，湖南小型振動試驗臺生產(chǎn)廠家，水平輸入孔接25厘米臺面）。臺面放置好后接上電源220V/50HZ。接著開始第二個步驟設(shè)定振動方式的參數(shù)。

對于運送中交通工具所產(chǎn)生的振動環(huán)境是屬于隨機振動，既使在同一時間內(nèi)，每個不 </p> <p> 同的頻率下均有不同的振動量，在執(zhí)行隨機波振動測試時，由于同時間不同頻率皆有 </p> <p> 振動量值。 </p> <p> 3、什么是加速度譜密度 </p> <p> 表示隨機信號的各個頻率分量所包的加速度方均值在頻域上是怎樣分布的。通常用ASD </p> <p> 表示，單位：m2/s3或是(m/s2)2/Hz。 </p> <p> 4、什么是功率譜密度 </p> <p> 表示隨機信號的各個頻率分量所包的功率在頻域上是怎樣分布的。通常用PSD表示，單位： </p> <p> g2/Hz。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

振動試驗機在使用時應(yīng)注意的幾個細節(jié)： </p> <p> 1.試件必須剛性地安裝在試驗臺面上，否則會產(chǎn)生諧振和波形失真，影響試件的試驗效果，試件在振動過程中，不要拆卸，一定要的話請先停機。 </p> <p> 2.試驗夾具需正確使用并確保已經(jīng)固定，以免造成人員傷害和設(shè)備破損。 </p> <p> 3.使用中如果發(fā)生任何異?，F(xiàn)象，要立即停止試驗，避免損毀機器。 </p> <p> 4.系統(tǒng)在運行中不能觸碰傳感器。 </p> <p> 5.工作時，不要把磁性或不宜接觸磁性的物件(如手表等物)靠近振動發(fā)生機。 </p> <p> 6.<span style="font-size:12px;">為了讓功率放大器模塊和臺體有充分的冷卻時間,必須在切斷信號以后,冷卻7至10分鐘后才可斷開功率放大器漏電斷路開關(guān)。</span> </p> <p> 7.不能在關(guān)閉功放之前先關(guān)控制箱和微機電源，不然會所放物品和振動臺的沖擊造成損壞。 </p> <p> <br /> </p> <p> <br /> </p><div
