推導了適合纜索承重橋梁的纜索單元；引入虛擬單元理論，提出適用於大跨纜索承重橋梁鋼箱梁的一種新方法?虛擬層合板單元法，該單元具有計算效率高，可以模擬復雜結構並滿足工程需要等諸多優越性。Considering the state - of - the - art of such kind of structural system, the author gives a simulative analysis of the system with the feiyunjiang bridge in wenzhou zhejiang province as an engineering example using three methods : 3 - d beam or bar fem, classical plate / shell fem and virtual laminated element method. the virtual laminated element method may deals with many key issues in simply - supported - continuous system easily such as the matter of actual material or virtual material, mesh replacement
針對國內外對先簡支后連續結構體系的研究普遍缺乏深度這一現狀，我們以浙江溫州瑞安市飛雲江大橋引橋為工程背景，運用空間梁桿系有限元、經典的板殼單元法以及虛擬層合單元法對該體系進行了施工模擬分析。On the basis of large - displacement virtual principle, the finite element equations of stable type suspension bridge containing towers are driven. the stiffness matrixes of the cable element, the bar element and the beam element using node coordinates are given, too. such method has not been found in reference books
論文從有限位移彈性理論的虛功方程出發，推導出穩定橋全橋結構的非線性有限元運動方程，還推導了用節點坐標表示的索單元、桿單元和梁單元的單元剛度矩陣，這一點在參考文獻較少見。Usually only select states are available and output feedback is used. it is shown that output feedback, while not as effective as full state feedback, is still able to damp vibration. thirdly, virtual vibration measurement and control instrument is developed using lab view and homemade daq, then experiments are performed to validate the conclusion of analysis results
最後，為了驗證在理論分析和數值模擬中得到的結論，利用虛擬儀器軟體labview和國產數據採集板開發了虛擬振動測控平臺，然後對附加主被動混合阻尼的懸臂梁結構，實現了結構振動控制，實驗結果表明主被動阻尼分離結構對低階模態振動具有更顯著的控制效果。The results are important for dam base excavation and engineering disposal. ( 2 ) arch dam can be regarded as an elastic ground cantilever system composed of vertical cantilever, horizontal arch, and torsion structures. the dissertation takes the arch dam as load diversion system of arch - cantilevers system located on the ground composed of elastic cantilever
（ 2 ）將拱壩虛擬為由座落在壩基塊體有限元上的一系列懸臂梁與水平拱組成，將懸臂梁視作由水平拱所支承的彈性地基梁，考慮徑向和切向調整，比以往的彈性地基梁只考慮徑向調整有所發展；而且用塊體元模擬壩基，也能較精確地模擬壩基多種斷裂構造等對壩體結構行為的影響。Starting from two well - accepted assumptions in theory of thin - walled beams, a general theory for linear analysis of curved beams with any open sections is established in this paper by using the principle of virtual work. the equations of equilibrium and natural boundary conditions are given
文章首先從薄壁構件理論的兩個基本假定出發，利用虛功原理，建立起一套精確的、可以應用於任意開口薄壁截面圓弧曲梁的線性理論，給出相應的平衡方程和邊界條件。Seek the sound cable tension to aim at minimum of maximum stress by the method of fem analysis combined with optimization. during optimization, use virtual lamina beam element to analyze the structure. the result of optimization of the cable tension of wenhui bridge shows this method is easy, effective and applicable
