0:00:00 點(diǎn)擊次數(shù)：1225</div> <div id="611661116616" class="ny_news_con"> <p>現(xiàn)今世界經(jīng)濟(jì)潮流,已從過(guò)去地域性的經(jīng)濟(jì)模式而走向性的經(jīng)濟(jì)貿(mào)易。無(wú)論是地域性市場(chǎng)或進(jìn)軍市場(chǎng)，高品質(zhì)的表現(xiàn)是不容諱言的。而振動(dòng)測(cè)試更是協(xié)助您產(chǎn)品躍入高品質(zhì)行列中不可缺乏的利器。</p> <p>產(chǎn)品達(dá)到用戶手中，在此過(guò)程中將有不同狀態(tài)之振動(dòng)產(chǎn)生，造成產(chǎn)品不同程度的損壞。而對(duì)于產(chǎn)品有任何損壞都不是廠商及客戶所愿意見(jiàn)到的，然而運(yùn)送過(guò)程所發(fā)生的振動(dòng)卻是難以避免，若一味的提高包裝成本，必將帶來(lái)嚴(yán)重而不必要的浪費(fèi)，反之脆弱的包裝卻造成產(chǎn)品的高成本，并喪失了產(chǎn)品形象及市場(chǎng)，這些都不是我們所愿見(jiàn)到的。</p> <p>振動(dòng)測(cè)試約在四、五十年前開(kāi)始萌芽，理論建立時(shí)，并無(wú)助于人們相信它的重要性，直到二次大戰(zhàn)時(shí)，許多的飛行器、艦艇、車(chē)輛及器材在使用后，意外的發(fā)現(xiàn)機(jī)件失零的比例相當(dāng)高，經(jīng)研究的結(jié)果發(fā)現(xiàn)，大都由于其結(jié)構(gòu)無(wú)法承受其本身所產(chǎn)生的長(zhǎng)時(shí)間共振，或搭載物品承受運(yùn)送共振所引起之，元件松脫、崩裂，而致機(jī)件失零甚而造成巨大損失。當(dāng)這項(xiàng)結(jié)果公布后，振動(dòng)測(cè)試才受到各界重視，紛紛投入大筆經(jīng)費(fèi)、人力去研究。爾后，對(duì)于振動(dòng)量測(cè)分析以至模擬分析的近代理論建立后，對(duì)振動(dòng)測(cè)試的方法及邏輯亦不斷改進(jìn)。尤其現(xiàn)今貨物的流通頻繁，使振動(dòng)測(cè)試更顯重要。</p> <p>然而振動(dòng)測(cè)試的目的，是在于實(shí)驗(yàn)中作一連串可控制的振動(dòng)模擬，測(cè)試產(chǎn)品在壽命周期中，是否能承受運(yùn)送或振動(dòng)環(huán)境因素的考驗(yàn)，也能確定產(chǎn)品設(shè)計(jì)及功能的要求標(biāo)準(zhǔn)。據(jù)統(tǒng)計(jì)的數(shù)據(jù)顯示提升3%的設(shè)計(jì)水準(zhǔn)，將增加20%的回收及減少18%的各項(xiàng)不必要支出。振動(dòng)模擬依據(jù)不同的目的也有不同的方法如共振搜尋、共振駐留、循環(huán)掃描、隨機(jī)振動(dòng)及應(yīng)力篩檢等，而振動(dòng)的效應(yīng)計(jì)有：一、結(jié)構(gòu)的強(qiáng)度。二、結(jié)合物的松脫。三、保護(hù)材料的磨損。四、零組件的破損。五、電子組件之接觸不良。六、電路短路及斷續(xù)不穩(wěn)。七、各件之標(biāo)準(zhǔn)值偏移。八、提早將不良件篩檢出。九、找尋零件、結(jié)構(gòu)、包裝與運(yùn)送過(guò)程間之共振關(guān)系，改良其共振因素。而振動(dòng)測(cè)試的程序，須評(píng)估訂定試驗(yàn)規(guī)格，夾具設(shè)計(jì)之真實(shí)性，測(cè)試過(guò)程中之功能檢查及后試件之評(píng)估、檢討和建議。</p> <p>振動(dòng)測(cè)試的要義在于確認(rèn)產(chǎn)品的可靠度以及提前將不良品在出廠前篩檢出，并評(píng)估其不良品的失效分析以期成為一個(gè)高水準(zhǔn)、高信賴度的產(chǎn)品。</p> <p style="text-align:center"><strong>常州億通分析儀器制造有限公司</strong></p> </div> <div
