摘要: 本文用高次有限元分析了任意橫截面形狀同軸線(xiàn)特性阻抗;給出了一個(gè)用二次元求解同軸線(xiàn)特性阻抗的通用程序。由于提出了一種便于編制通用程序的計(jì)算機(jī)自動(dòng)區(qū)域剖分方法,使整個(gè)分析過(guò)程十分簡(jiǎn)便有效,大大提高了解題效率。文中對(duì)十余種不同橫截面形狀同軸線(xiàn)特性阻抗的計(jì)算,有力地證實(shí)了該程序的可靠性,通用性和準(zhǔn)確性。同時(shí),在數(shù)值分析的基礎(chǔ)上,對(duì)高次元的解題效能進(jìn)行了討論。

Abstract: The high-order finite-element method is used for analyzing the characteristic impedances of the coaxial lines with arbitrary cross-sectons. A standard program with second order element analysis for calculating the characteristic impedances of various coaxial lines is developed. A computer automatic division technique is proposed to faciliate the development of the general program. As a result, the whole analysis procedure becomes simple and the solusion efficency raises tremendously. The calculations of the... -
