The contents include : based on the previous research and the data of experimentations, the author researches and develops a kind of satisfactory semi - empirical formula of nonlinear temperature distribution, and calculates the temperature stress of rigid - framed arch bridge by the fem. the temperature effects of bridge structure by annual and sunlight temperature difference are discussed, it indicates that the temperature effect of annual temperature difference is small but the temperature effect of sunlight temperature difference is great and the temperature stress along beam depth resulted from sunlight temperature difference is nonlinear. with the comparison between the temperature effects of different position of bridge, the results show that where the section of bridge is small, the temperature stress of it is large
本文主要包括以下內容:從理論上研究並結合實測資料發展了一種比較理想的半經驗溫度場非線性分佈公式,並將有限元方法應用於剛架拱橋結構溫度應力的計算中,對橋梁結構進行整體溫度應力分析;討論了年溫差和日照溫差引起的橋梁結構的溫度效應,表明年溫差引起的溫度效應較小,而日照溫差引起的溫度應力較大且沿梁高呈非線性分佈;分析比較了橋梁結構各個部位的溫度效應的大小,可知截面越小溫度拉應力越大,受力越不利;並對箱梁結構由於構造不同引起的縱向與橫向的溫度效應大小進行了探討,發現在頂板下緣也會出現相當大的溫度拉應力,並且梗腋的存在反而增加了頂板底部的溫度拉應力;還對幾種相近的剛構式橋型的溫度效應進行了分析對比,總結了這些橋型針對溫度效應的優劣,並提出相應的針對性措施。In the paper, prescale technology, interpolate method, averaging method and multiple period synchronization method are used to measure the frequency accurately. diode demodulating technology, and power attenuated method or probe coupling & water load technology are employed to measure the power of high power microwave. isothermal technology is used to improve the stability of demodulator and to expend the range of square linear region
本文採用預分頻法、內插法、多周期同步法、平均法實現了頻率的精確測量;利用二極體檢波技術,結合衰減法或探針耦合+水負載技術實現了大功率微波功率的測量;採用恆溫技術提高了二極體檢波器穩定度;完成了單片機串口通信協議設計和系統電磁兼容的分析和設計。The traditional level measuring methods can n ' t meet our demand because the subjective investigated is in such a poor systemic condition that the temperature is a little high and there ' s so many mill dust and steam there. in this article we perform systemic discuss and research against the dynamic level measuring method under special working condition on the basis of analyzing kinds of level measuring technique in and abroad. first we establish the pressure distribution mathematic model in storage bin and then deduce the mathematic relation between level height and the uniform stress on the bottom of the bin and designed a resistance compressive stress sensor used for the special condition and put forward a resoivement according to its zero excursion existing in practical use
由於本研究系統被測對象環境溫度較高且潮濕,同時料倉中有大量粉塵及蒸汽,因此傳統的料位檢測方法不能滿足本測試要求。本文在分析國內外各種物位檢測技術的基礎上,針對特殊工況下動態物料高度的檢測進行了系統的探討與研究。首先建立了料倉中的壓力分佈數學模型,推導出料位高度與倉底均布壓力間的數學關系式,並據此設計了中溫電阻應變式壓力傳感器,同時對它在實際應用中存在的零點漂移等問題提出了改進措施,提高了傳感器性能,解決了上述特殊工況下動態物料檢測的技術難題。Multi - span plastic greenhouse structure design theory has been studied systemic which include design loads, design methods and system optimization designs aimed at the situations above - mentioned, meanwhile, theory analysis and designs have been completed for series east - china multi - span plastic greenhouses in accordance with the local climate characteristic. some elementary conclusions are summed up : ( 1 ) in the aspect of multi - span plastic greenhouse structural design loads researches, based on the contrast analysis of loads provided in foreign and chinese standards, analysis and discussion are mentioned about the definition loads, the estimation and load cases for multi - span plastic greenhouse structural design in details, some conclusions are summed up first : i, wind load : under the present conditions, it is unnecessary to
得到一些初步的結論: ( 1 )在連棟塑料溫室結構設計荷載研究方面,從分析比較國外關于溫室建築及我國工業與民用建築設計荷載規范的角度出發,針對連棟塑料溫室結構設計中的荷載定義方法、計算取值、荷載組合等進行了較深入的探討和分析,首次得到以下結論: 、風荷載:在現有條件下,考慮風壓高度變化系數、陣風作用因子和風荷載體型系數,按中國建築結構荷載規范( cbj9 ? 87 )計算風荷載是可以的,不必進行重現期博士學位論文摘要修正。( 2 ) because of t he variability of rock subjected to outside action, three new conceptions : postive damage basic damage and negative damage, are suggested, which can deal with the condition that rock density became large. ( 3 ) the present damage variables based on ct number mostly include ct average number of the rock without damage, which is difficult to measure, so a new damage variable, which includes the average ct number is proposed, on the other hand, strain equal theory is generalized because the one put foreword by lemaitre is not good enough to use. ( 4 ) a axial damage constitutive equation is proposed and testified. ( 5 ) with the circle times, the damage propagation laws of two different rocks, subjected to circle of freezing and thawing, are studied, and in the analysis process, traditional analysis method including average ct number and is used, some important conclusions are reached : inner damage of soft rock containing a large mount of apertures is largely propagating with the time increasement of circle, however, at the preliminary time, the hard rock containing a small mount of aperture is a little propagating, at late time, the influence become large ; ( 6 ) zone separation and statistics frequency put forward is used to analysized the three different damage propagation in the open circumstance, when they are subjected to the different circle times of freezing and thawing, in which the temperature variability is linear, different freezing rate, and different freezing temperature, and no water is supplied during the test
在研究過程中本文主要做了以下工作: ( 1 )針對巖石損傷變化較小時,運用ct均值和方差分析不方便的缺陷,本文提出運用對ct數范圍劃分區段的方法,根據各區段統計頻率的變化規律來分析損傷擴展狀況; ( 2 )針對巖石受到外部作用的多變性,本文提出了基準損傷,正損傷,負損傷的概念,在某種程度上考慮了巖石受到外部作用時的壓密情況; ( 3 )現有的基於ct數的損傷變量大多需要用到巖石基體的ct均值,這實際上是很難觀測到的,因此本文建議了一個可運用巖石初始狀態ct均值的損傷變量,由於現有的勒邁特教授應變等價原理使用上的不便,本文在其基礎上進行了推廣; ( 4 )建議了一個可用巖石初始狀態ct數和彈性模量的單軸損傷本構方程,並用算例進行了驗證; ( 5 )對兩種不同巖石在開放環境下受到凍融循環作用且融化過程中補水時,內部損傷隨凍融循環次數增加的擴展規律進行了探討,主要運用了常規的ct均值和ct方差的分析方法進行分析,試驗發現:對于孔隙率和含水率較高,密度和強度較低的軟弱巖石,凍融循環次數對損傷結構的擴展有明顯的影響,而對于孔隙率和含水率較低,密度和強度較高的硬巖,凍融循環次數對其損傷結構擴展初期由於含水率低的原因,影響不是太大,而後期由於水補給后,含水率較高的原因,凍融影響逐漸增大; ( 6 )運用了本文提出的區段劃分和統計頻率的方法,深入地分析了開放環境下的線性溫度變化的凍融循環次數,凍結溫度,凍結速度不同巖石作用時,其內部損傷隨凍融循環次數,凍結速度和凍結溫度變化的擴展規律,需要指出的是除了在試驗前飽水外,凍融過程中沒有補水。分享友人
