A predictor - corrector method to get the forward solution of a 6 - sps parallel manipulator was presented based on the principle of position tracking 摘要以6 - sps并聯(lián)機(jī)構(gòu)為例,基于路徑跟蹤原理,提出一種求解并聯(lián)機(jī)構(gòu)位置正解的預(yù)估校正法。
Some new predictor - corrector methods and three - steps iterative algorithms for solving multivalued general mixed quasi - variational inequalities is presented by using the auxiliary principle and resolvent operator technique , respectively 利用輔助原理和預(yù)解算子技巧,提出了解一般混合集值擬變分不等式的預(yù)估-校正算法和三步迭代算法。
In order to apply the research results of this paper to the optimum design of computer for cpw , the analytical closed - from of expressions is the best choice . so conformal mapping theories are used to analyze cpw ' s by this paper . the optimum programming , the numerical inversion of conformal transformation and the numerical predictor - corrector method have been utilized to calculate the characteristic parameters and field patterns of cpw ' s 為了使本論文的研究成果便于應(yīng)用于共面波導(dǎo)的計(jì)算機(jī)優(yōu)化設(shè)計(jì)中,最好方法是得到封閉的解析表達(dá)式,所以本論文采用了保角變換理論宋分析非對稱共面波導(dǎo),并且應(yīng)用了優(yōu)化計(jì)算方法、保角變換反演技術(shù)和數(shù)值預(yù)測糾正算法對各種非對稱共面波導(dǎo)的特性以及場結(jié)構(gòu)進(jìn)行求解。
In this thesis a numerical model to solve the planear 2 - d depth - integrated flow ( dif ) has been established with irregular body - fitted mesh finite volume method and explicit maccormack predictor - corrector method and applied to the study of damming caused by a bridge pier under 14 working conditions varied with the combination of different pier shape . flow rate and contraction ratio 本論文采用非規(guī)則貼體網(wǎng)格有限體積法和顯式maccormack預(yù)測-校正法求解平面二維水深積分方程,對明渠水流運(yùn)動的數(shù)值模擬方法進(jìn)行了研究,并且應(yīng)用該數(shù)值模型計(jì)算了14種不同的橋墩體型、來流、收縮比的組合工況下的橋墩壅水問題。
