米姬:這是全新的。革命性的改良。沒有肩帶,也沒有背帶,但是所有胸罩的功能它都有。運用懸臂式橋梁的原理來支撐。The content of this thesis comes from the fujian natural science found following research task 。 it studies on a space cantilever single beam attached to a moving support 。 inertia forces which are brought by the support ' s movement , are acceded to the equivalent initiative forces and the equivalent initiative moments 。 when we consider the relation of the forces and deformation , we change the method of material mechanical analysis to the elastic mechanical analysis 。 further more , we discusses the feasibility of the method which uses the multi - rigid - body discrete model to simulate the dynamic characteristic of a elastic body 。 first , the finite segment method is adopted to establish the models of the beam 。 based on kane ' s equations , dynamic math - model for the beam are derived 。 and by use of c - language and runge - kutta procedure , the computer - oriented procedure can give the whole responses of the beam 。 second , with compare to the numerical examples , the method which uses the multi - rigid - body discrete model to simulate the dynamic characteristic of a elastic body which is under the condition of movement is verified to be feasible 。
本論文為福建省自然科學基金后續研究課題,以已知支撐運動的單個空間懸臂梁為對象,在等效主動力與等效主動力矩中加入支撐轉動引起的慣性力,並在考慮力與變形關系時,用更一般的彈性力學分析代替材料力學分析,進一步研究用多剛體離散模型來模擬其動力學特性的可行性。首先,用有限段建立機械臂的多剛體離散模型,用kane動力學方法建立其動力學方程。並用c語言編制演算法程序,採用了四階runge - kutta積分程序求解微分方程組,給出構件的全部動態歷程。The construction of the bridge began in oct 1999, and the closing up of the steel tube was in dec 2000. during that period, i learned and analyzed the current construction methods fairly comprehensively, and collected the construction technique data of the cfst arch bridges having been built. based on this, aided by the simulation of construction procedure using finite element program, i proposed the operation program to make the steel tube segment be located at one time, and the scheme of dividing rooms to segment pouring
大橋於99年10月開工, 2000年12月主橋鋼管合龍,在此期間,本人就目前鋼管混凝土拱橋的施工方法進行了較全面的了解和分析,搜集了此類已建橋梁的施工技術資料,在此基礎上,又藉助有限元程序對施工過程模擬計算的支持,提出了在梅溪河大橋懸臂安裝過程中,鋼管節段一次就位的操作程序和鋼管混凝土分倉灌築的方案,並為施工單位采納應用。Against classical dynamic balancers of crank and connecting rod mechanism, the test system has virtue hereinafter : ( 1 ) supporting structure adopt projecting beam uniquely. the signal of vibration provoked by crank and connecting rod mechanism revolving is concentrated to strain beam. the signal is not only abundance, but also easy to test and the test sensitivity is great
與傳統的曲柄連桿機構動平衡機相比,這種測試系統具有以下優點:支承結構採用獨特的懸臂梁式結構,曲柄連桿機構在運轉過程中振動規律完全映射到支承梁的應變上,振動信號豐富且易測試、靈敏度高。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。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。Paper ' 21 has adopted this method in the cantilever beam and simple beam ' s crackle discerning. the result indicates that modal flexibility curve is easy and just needing few calculating amount
文獻等在懸臂梁和簡支梁的裂紋識別中採用了該方法,結果表明,柔度曲率法具有計算量小和簡便易行的優點,而且僅需要低階模態信息即可獲得很好的精度。分享友人
