MIL-STD-810G是(shi)美國(guo)軍工標準(zhun)(zhun)，國(guo)內對(dui)應的標準(zhun)(zhun)為GJB-150A-2009該標準(zhun)(zhun)涉及的是(shi)軍工設備(bei)的振動和環境試(shi)驗。GB/T 2423.10—1995、IEC60068及電(dian)子電(dian)器試(shi)驗標準(zhun)(zhun)等(deng)等(deng)，

    振動試驗臺是(shi)用(yong)于(yu)指評定(ding)產品在預期的(de)使用(yong)環境中抗振(zhen)(zhen)(zhen)能力(li)而對受振(zhen)(zhen)(zhen)動(dong)(dong)(dong)的(de)實物或(huo)(huo)(huo)模型進(jin)行的(de)試(shi)驗(yan)。根據施加的(de)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)載荷(he)的(de)類型把振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)分(fen)為正(zheng)弦(xian)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)和隨機振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)兩種(zhong)。正(zheng)弦(xian)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)包括定(ding)額振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)和掃描正(zheng)弦(xian)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)。掃描振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)要求振(zhen)(zhen)(zhen)動(dong)(dong)(dong)頻率按一(yi)定(ding)規律變化，如(ru)線性(xing)(xing)變化或(huo)(huo)(huo)指數規律變化。振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)主要是(shi)模擬各種(zhong)產品的(de)結(jie)(jie)構(gou)設(she)計及(ji)電(dian)子電(dian)路在各種(zhong)抗振(zhen)(zhen)(zhen)能力(li)，試(shi)驗(yan)參數為頻率范圍(wei)、振(zhen)(zhen)(zhen)動(dong)(dong)(dong)幅值(zhi)和試(shi)驗(yan)持續(xu)時間。振(zhen)(zhen)(zhen)動(dong)(dong)(dong)對產品的(de)影響有:結(jie)(jie)構(gou)損(sun)壞(huai)(huai)，如(ru)結(jie)(jie)構(gou)變形、產品裂紋或(huo)(huo)(huo)斷(duan)裂;產品功(gong)能失效或(huo)(huo)(huo)性(xing)(xing)能超(chao)差(cha)，如(ru)接觸不(bu)良(liang)、繼電(dian)器誤動(dong)(dong)(dong)作等，這種(zhong)破(po)(po)(po)壞(huai)(huai)不(bu)屬于(yu)永久(jiu)性(xing)(xing)破(po)(po)(po)壞(huai)(huai)，因為一(yi)旦振(zhen)(zhen)(zhen)動(dong)(dong)(dong)減(jian)小(xiao)或(huo)(huo)(huo)停止，工(gong)作就能恢(hui)復正(zheng)常(chang);工(gong)藝性(xing)(xing)破(po)(po)(po)壞(huai)(huai)，如(ru)螺釘或(huo)(huo)(huo)連接件松動(dong)(dong)(dong)、脫焊。從振(zhen)(zhen)(zhen)動(dong)(dong)(dong)試(shi)驗(yan)技(ji)術發(fa)展趨勢看，將采用(yong)多點(dian)控制技(ji)術、聯合激動(dong)(dong)(dong)技(ji)術。

       本試驗(yan)是(shi)(shi)模(mo)擬(ni)產品在(zai)運(yun)輸、安裝及使用環(huan)境下所遭遇到的(de)(de)各種(zhong)振(zhen)動(dong)(dong)(dong)環(huan)境影響，用來確定產品是(shi)(shi)否能(neng)承受各種(zhong)環(huan)境振(zhen)動(dong)(dong)(dong)的(de)(de)能(neng)力。正弦(xian)振(zhen)動(dong)(dong)(dong)是(shi)(shi)實驗(yan)室中經常采用的(de)(de)試驗(yan)方法(fa)，以模(mo)擬(ni)旋轉、脈動(dong)(dong)(dong)、震蕩(dang)（在(zai)船舶、飛機、車輛、空間(jian)飛行器上(shang)所出現的(de)(de)）所產生的(de)(de)振(zhen)動(dong)(dong)(dong)以及產品結(jie)構(gou)共振(zhen)頻率分析和(he)共振(zhen)點駐留驗(yan)證為主，其(qi)又分為掃頻振(zhen)動(dong)(dong)(dong)和(he)定頻振(zhen)動(dong)(dong)(dong)兩種(zhong)，其(qi)嚴苛(ke)程(cheng)度取(qu)決(jue)于頻率范圍、振(zhen)幅值、試驗(yan)持續時間(jian)。隨機振(zhen)動(dong)(dong)(dong)則以模(mo)擬(ni)產品整(zheng)體性(xing)結(jie)構(gou)耐震強(qiang)度評估以及在(zai)包裝狀態下的(de)(de)運(yun)送環(huan)境，其(qi)嚴苛(ke)程(cheng)度取(qu)決(jue)于頻率范圍、GRMS、試驗(yan)持續時間(jian)和(he)軸向。
