( 2 ) aiming at the discrete structure of composite shells , this thesis proposes two integer coding method , then uses one of them to optimize composite shells ( 2 )針對(duì)復(fù)合材料層合殼的離散型優(yōu)化特點(diǎn),提出兩種整數(shù)型編碼方式來表征層合殼結(jié)構(gòu)參數(shù)。
This thesis points out the option of preparing - selected controlling mode is the specialization option by setting discrete structure under specialization economy 分析得出了物流模式發(fā)展的趨勢(shì)專業(yè)化的物流模式將是我國未來的物流模式,物流產(chǎn)業(yè)將成為我國經(jīng)濟(jì)中的重要產(chǎn)業(yè)之一。
The paper presents a solution method for the transient temperature field , in which the finite element method or the finite difference method is used to get discrete structure , and the finite difference method is used to get discrete time in order to simplify the transient thermal conductive equations as a set of linear equations as a set of linear equations at different moment 本文提出對(duì)空間采用有限元法或有限差分法,而對(duì)時(shí)間采用有限差分法將瞬態(tài)熱傳導(dǎo)方程簡(jiǎn)化為不同時(shí)刻的線性方程組以求解瞬態(tài)溫度場(chǎng),用以求解大體積混凝土在固化過程中不同時(shí)刻的溫度分布。
Generally , structure ' s stresses , not internal force , can be obtained by analyzing discrete structures with routine solid elements , but internal forces of structure such as moment , axial force and shear force are required in the design criterions which are working in the design of hydraulic structures and industrial and civil structures . a convenient method based on the equilibrium condition of internal force and element ' s stresses is presented in this paper . this method can directly solve constraining internal forces on the designated sections , and then solve the moment , axial force and shear force on the corresponding sections 一般情況下用常規(guī)的實(shí)體單元對(duì)結(jié)構(gòu)進(jìn)行離散后求解得到的是結(jié)構(gòu)的應(yīng)力而非內(nèi)力,而現(xiàn)行水工結(jié)構(gòu)及工業(yè)與民用建筑結(jié)構(gòu)設(shè)計(jì)規(guī)范的設(shè)計(jì)準(zhǔn)則主要是建立在結(jié)構(gòu)內(nèi)力(如彎矩、軸力、剪力等)基礎(chǔ)上的,本文采用了一種根據(jù)單元應(yīng)力及內(nèi)力平衡條件直接求解指定截面上的約束內(nèi)力,并進(jìn)而求解相應(yīng)截面上的彎矩、軸力、剪力等的方法,該方法不需要對(duì)應(yīng)力進(jìn)行擬合。
