能產生良好的可塑性,能圍繞模子成型,並在去條模子后具有足夠的強度保持其形腔,便於灌金屬熱液。Performance for a piezoresistive transducer pressure sensor to thermal and pressure environments can be predicted by finite element method. a simplified 1 / 8 model, considering silicon dioxide and nitride process as well as stack anodic bonding and adhesive bonding processes, was developed. the fem results were found to be comparable to experimental data. case studies suggested that pyrex stack induces certain amount of non - linearity, while it isolates hard epoxy nonlinear effect. flexible epoxy bonding or soft adhesive bonding is preferred to the packaging process. the viscoelasticity and viscoplasticity of bonding material will result in hysteresis and drift errors to sensor output. however, soft adhesive s influence on sensor can be ignored under relative stable environments. more over, detailed design and process information will help to improve modeling application
熱、壓環境下壓阻變換壓力傳感器的性能可以通過有限元方法預測.這里研究了簡化的1 / 8模型,模型考慮了二氧化硅和氮化硅生成過程及堆陽極鍵合和膠粘結合過程.結果發現有限元預測結果和實驗數據具有可比性.範例研究表明,硼硅堆導致產生一定的非線性,但它隔離了硬環氧樹脂的非線性.在包裝過程中最好使用柔性環氧黏合或軟黏膠性結合.黏合材料的黏彈性和黏塑性將會導致傳感器輸出的滯后和漂移誤差.然而,在相對穩定的環境下,軟黏合劑對傳感器的影響可以忽略.此外,詳細的設計和過程信息有助於提高模型的適用性From experimental result, i preliminarily know that eps is good thermal insulation material because the absorption of water is low and heat insulation is good, it is practicable at preserving temperature field of frozen earth roadbed and bringing frozen disaster under control ; second, according to the analysis of the eps that is applied into practical project, i have studied the practical effect which eps preserve roadbed temperature field, and the influence that was made after building field. i have get that eps can influence moisture content and frozen upper limit, through practical measuring data, i have studied freezing and expanding quantity and melting and submerging quantity during a complete frozen and melting cycle as well as have expanded and proved the practical application effect of eps with some reference significance to deep research of some connected problems. finally, through computer data analysis, setting up the analytical model of finite unit, i have simulated the temperature field of roadbed heat preservation, then expounded and proved that the height of embankment influenced the effect of thermal insulation material
其一是對聚苯乙烯泡沫塑料( eps )保溫板以及天然路基土層、路堤填料進行了室內試驗分析,結合國內外現在的有關科研成果,綜合確定其各項特徵參數;從試驗結果初步認識到聚苯乙烯泡沫塑料是一種吸水率低,隔熱性好的保溫材料,在凍土路基溫度場的保護和凍害治理方面是可行的;其二通過eps保溫板在現場工程實踐中的應用分析,研究了保溫板在保護路基土層溫度場的實際效果以及修築路堤后造成的影響,保溫板對土體含水量、凍結上限的影響,通過實測資料,研究了在一個完整的凍融周期內整個路基的凍脹量和融沉變形量,論證了保溫板的實際應用效果,對有關問題的進一步研究和相關工程設計具有參考意義;其三,通過計算機數值分析,建立有限元分析模型,對保溫路基的溫度場進行了模擬計算,論證了路堤高度對保溫材料效果的影響。The results of the experiments show that the ti3al - tcll dual alloys, by vacuum - electron - beam weld, hot die forging and 680c / 12h, ac, heat treatments, have satisfied synthesis properties of intensity, plasticity, hardness. and also it is the feasiblie way. this will establish the supporting technology for the manufacture of the compress disk in the areoengine
實驗結果表明,經真空電子束焊接ti _ 3al ? tc11雙合金經過熱模鍛造和680 12h , ac或815 1h + 700 8h , ac熱處理后,焊接區組織過渡均勻,可以使得焊縫處強度在室溫拉伸時高於ti _ 3al ,而在600拉伸時高於tc11合金,獲得強度、塑性、硬度均令人滿意的綜合性能,且是一條可行的工藝路線。Acrylics are synthetic resins made from derivatives of acrylic acid. thermoplastic acrylics ( lacquers ), thermosetting acrylics, and acrylic latexes are available ; the latter two are used in coil coating
丙烯酸塗料是由丙烯酸衍生物經化學合成的樹脂。熱塑性丙烯酸和熱固型丙烯酸(塗料)和丙烯乳液是可供應的,后兩者可用於卷鋼塗料中。If there are high temperature gradient between cool liner and hot liner, compressive plastic strain appear at that transient time, which lead to gas film wall bearing high tensile stress at high temperature. high tensile stress is one of main reasons which destroy combustor
分析表明,起動過程中由於熱傳導滯后引發的溫度梯度可以導致火焰筒氣膜唇邊在起動瞬間發生較大的壓縮塑性應變,進而使得該區域在工作時承受較高水平的拉伸應力,高的拉應力會導致火焰筒萌生裂紋。分享友人
