摘要為了研究油基鉆井液性能和固井質量之間的直接關系，採用新建立的評價方法人工巖心法，考察了油基鉆井液體系及其主要組分對固井作業中第一、第二界面剪切膠結強度的影響規律，以及不同混漿比例下對水泥漿膠凝強度、初凝時間、終凝時間和水泥石抗壓強度的影響規律。Based on the continuous damage theory, considering the shear effect, the high - order shearing, flexural and in - plane deformation coupling model is built ; through the nonlinear fem analysis of rc beams strengthened with frp, the damage theory and damage course is researched ; compared with experiment results, it shows that the model is effective ; the fem analysis software is prepared to provide simple and effective method for the engineering application ; using the soft the frp strengthened beams before and after damage is modeled so as to provide the theory base for engineering application
摘要基於連續損傷理論，考慮膠層的剪切效應，建立frp加固鋼筋混凝土梁的高階剪切彎曲及面內變形耦合模型，編制了有限元分析的軟體，進行非線性有限元分析；通過與已有的試驗結果進行對比，證明該模型的簡單，有效性；利用該軟體對未加固混凝土梁，初始進行加固的混凝土梁以及最大拉應變達到極限值時進行加固的混凝土梁等幾種情況進行數值模擬。Some stiffness matrices of special elements such as rubber bearings and components with field are derived from primary - secondary and inverse transform in structural matrix analysis. then, seismic response analytical models and non - isolated continuous rigid frame bridges are set up, while considering the interaction of soil - pile - structure and traveling wave effect simultaneously. finally, the seismic time history response of the two models is calculated by means of the finite element method, and the results show that the isolated bridge posses powerful earthquake resistance
首先論述了公路大跨徑橋梁的地震反應分析方法，其中包括樁-土-結構相互作用、行波效應等因素對結構物的影響；其次，利用結構矩陣分析中的主從變換和逆步變換，推演了幾個特殊單元的剛度矩陣，包括橡膠隔震層單元和帶剛域構件單元；最後，考慮樁-土-結構相互作用和行波效應的結合，分別建立隔震與非隔震連續剛構橋地震反應分析模型，通過有限元法對兩種結構進行時程分析，結果表明：隔震層上部結構的地震加速度反應、位移反應均明顯減小，這說明隔震的連續剛構橋具有很好的抗震能力。The main research is as follows : analyze and research the boundary constraint and the structure characteristic and segment the frame making use of the shell element, the pipe element etc. on the base of it the practical finite element model has been established ; analyze the mode of the frame by dint of the finite element model. and get the inherent frequency and the vibration mode of the frame. tentatively estimate the dynamic characteristic of the frame and analyze the inherent frequency that may be lead to the resonance
論文的主要研究工作如下：分析研究車架的邊界條件和結構特性，並用殼、管等單元對該車架進行離散，建立一種切實有效的車架有限元模型；對該車架的有限元模型進行模態分析，求得其的固有頻率和振型，並對車架的動態特性做出初步評估，分析可能引起車架振動的固有頻率；在模態分析基礎上，研究發動機輸出的簡諧力引起的車架位移響應（即諧響應分析） ，以考察摩托車車架各部位的振動情況並與模態分析對比，分析是否與該車架的固有頻率相耦合而導致共振；在深入研究車架的模態分析及諧響應分析、清晰地認識了摩托車車架動態特性的基礎上，分析並提出了採用橡膠減震器對車架進行隔振的減震方法。The preserved remains of two prehistoric men discovered in an irish bog have revealed a couple of surprises - one used hair gel and the other stood 6 foot 6 inches high, the tallest iron age body discovered
