thermography

Through experimentation , it has a deep study on the ir thermograph to perception depth of the delaminated defects , the perception area of defects , the distinguishing instances of the different forms of defects . then the results show that to those defects whose burying depths are more than 50mm , and delaminated defects whose the areas are smaller than 30 ? 30mm2 , it is rather hard for the ir thermogrpahy to detect 從實驗的角度,在紅外熱成像檢測法對空鼓缺陷的感知深度、缺陷的感知面積、不同形狀的缺陷的分辨情況進行了深入研究,結果表明對一些埋設深度> 50mm的缺陷,面積< 30 30mm2的空鼓缺陷,紅外熱成像檢測法對這些缺陷的檢測已相當困難。

Because of its good electrical conductivity , cfrc specimens will engender joule effect when a relatively low voltage was added to them . if there are flaws inside , the surface temperature distribution of the specimens should be uneven . therefore , infrared thermograph ndt can be conducted 利用碳纖維混凝土良好的導電性,通過對碳纖維混凝土試件施加較低的電壓,使其產生焦耳效應,如果試件內部存在缺陷,將在表面產生溫度差,從而可以利用紅外熱像技術進行無損檢測。

Its principle is : a laminated structure ( beam or plate ) with delamination consists of undelaminated region and delaminted region which can be divided to upper and lower parts . when a low - amplitude and high - frequency excitation has the frequency close to some part ' s natural frequency , this part will resonate and certain amount of mechanical energy will convert to heat so that the delaminated region ' s temperature exceeds greatly that of the undelaminated region . therefore the delamination can be located by means of infrared thermograph 其原理是具有脫層的層合材料構件(梁或板)包含脫層區域及未脫層區域,脫層區域分為上下兩部分,若對層合材料構件施加小振幅、高頻率的振動激勵,當激勵頻率恰好接近其中一部分的固有頻率時,該部分就會產生共振響應,部分機械能將轉化為熱能,使脫層區域的溫度遠高于未脫層區域,借助紅外熱像儀即可顯示出脫層的位置。

On the research of cfrc , infrared thermograph detection under joule heat by adding voltage to the cfrc specimens is found to be a feasible and effective method of inspection , which can avoid the defects 在碳纖維混凝土( cfrc )的研究中發現,對碳纖維混凝土試件進行外加電壓的焦耳內熱源紅外檢測可以改善上述存在的局限性。

The examples to diagnose transformer faults with measuring element method by electro microscopy , infrared thermograph and icp plasma emission spectrum are introduced 摘要介紹了應用掃描電鏡測量元素法、紅外成像分析法、等離子發射光譜法檢測大型變壓器故障的實例。

Combined with experimental data , this paper conducted the theoretical analysis and computer simulation of the infrared thermograph ndt 本文結合實驗,針對機敏混凝土結構缺陷的焦耳內熱源紅外無損檢測過程,進行了理論分析和計算機模擬。
