</p> <p> 1、什么是定頻振動 </p> <p> 定頻振動是指在規(guī)定的固定頻率點上進行各種振動參數(shù)不同量級的試驗。 </p> <p> 2、定頻振動主要用于哪些方面 </p> <p> 1）耐共振頻率振動：在產(chǎn)品振動頻響檢查時發(fā)現(xiàn)的明顯共振頻率點上，施加規(guī)定振動 </p> <p> 參數(shù)振幅的振動，以考核產(chǎn)品耐共振振動的能力。 </p> <p> 2）耐預(yù)定頻率振動：在已知的產(chǎn)品使用環(huán)境條件振動頻率時，可采用耐預(yù)定頻率的振 </p> <p> 動試驗。其目的還是為考核產(chǎn)品在預(yù)定危險頻率下承受振動的能力。 </p> <p> 3、什么是臨界頻率 </p> <p>

因此需對特定零組件搜尋它的共振特性，再依其特性執(zhí)行共振點的加振試驗。 </p> <p> 4、什么是共振頻率 </p> <p> 共振頻率：產(chǎn)品出現(xiàn)共振的頻率。 </p> </p><p> 振動臺之振動測試必須知道的 </p> <p> 1、什么是臨界頻率 </p> <p>

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。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，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，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)。模擬汽車運輸振動試驗臺鏈條驅(qū)動，堅固耐用。安徽定制型振動試驗臺公司</p><p
