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。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。
