Because it is impossible to adjust the air bearing absolutely balance, the difference between mass center and rotation center must lead to a notable gravity disturbance torque. in the process of identification, modeling and identification of gravity disturbance torque is considered, and an extended kalman filter is educed for identifying air bearing inertia matrix and gravity disturbance torque, and then the algorithm is validated
由於氣浮臺平衡調試方法和手段的限制,實驗過程中氣浮臺質心與轉動中心有一定的位置偏差,必將導致較大的重力干擾力矩,在辨識演算法的推導過程中,重點考慮了重力干擾力矩的建模和參數辨識問題,推導了氣浮臺的轉動慣量和重力干擾力矩辨識的擴展卡爾曼濾波演算法,並對演算法進行了數學模擬和全物理模擬驗證。Based on plane section assumption, this paper presents the methods of calculating the ultimate strength of the columns strengthened with cfrp, and makes a simplification of the methods. a fortran program on nonlinear method is presented to numerically analyze the characteristics of large eccentrically loaded columns strengthened by longitudinal straps of cfrp, calculating results compare well with experimental data
本文在平截面假定的基礎上分別推導了碳纖維布縱向粘貼大偏心受壓柱的正截面承載力校核和截面加固基本計算公式,並對公式進行了相應的簡化;運用fortran語言編制相應程序對縱向粘貼碳纖維布大偏壓柱進行了數值分析,本文公式計算結果和程序計算結果均與試驗結果吻合良好。In the formula, our experience in structural strength design and the experimental results are considered. and such factors are also considered as differences in materials of the skin and the reinforcer, effects of bending, torsion, stretching and offcenter of the reinforcer. furthermore, through post - buckling stress analysis of the skin, it is shown that even low stress level will result in buckling of the skin, but the skin still has loading capacity
在總結過去結構強度設計和試驗分析的基礎上,應用扁殼理論,在廣義力與廣義應變關系中考慮了蒙皮與加筋不同材料以及加筋的彎曲、扭轉、伸縮和偏心等的影響,推導出適合於工程應用的加筋殼結構軸壓屈曲臨界載荷的計算方法;並通過對薄壁結構蒙皮后屈曲應力分析,說明蒙皮在很低的應力水平時就出現失穩現象,但失穩后的蒙皮仍具有一定的承載能力。Through the experimentation for the physical performance of cfpb masonry under local compression, the author has observed the deformation and failure of cfpbm. based on the mathematical statistics and regression analysis of the experimental data, the author derived a feasible and common formula for counting the cfpbm ' s local compression strength regarding the different local compression locations, analyzed stress distribution of local bearing masonry under beams end, and provided the calculating formula on effective supporting length of beam end in brick masonry. as the results of experiments demonstrate, owing to the cfpb ' s own holes " system, the beneficial effects, the bounding effect of surrounding masonry and the spread effect of force, have not developed completely
試驗結果分析表明:由於多孔磚自身的孔洞結構,砌體內部的圍箍作用和力的擴散作用未得到充分發揮,局壓強度雖較軸心受壓強度有所提高,但仍低於同情況下實心磚的局壓強度;當有上部荷載作用時,對砌體局壓有利的懸臂卸荷作用和內拱卸荷作用均不明顯,因此在推導梁端局壓強度計算公式時,未考慮此可能存在的有利影響,計算偏安全;局壓強度提高系數公式除採用規范公式(二項式)的表達式,還用對數式進行了回歸推導,得到了一個較為普遍的公式;論文還對梁端局壓的梁端有效支承長度計算公式進行了回歸推導。分享友人
