重分析方法研究進(jìn)展及展望
發(fā)布時(shí)間:2019-05-08 03:52
【摘要】:重分析方法作為一種能夠根據(jù)初始計(jì)算結(jié)果快速估計(jì)修改后結(jié)構(gòu)的快速計(jì)算方法,近幾十年來得到了廣泛研究,并取得了一系列具有理論價(jià)值和工程意義的成果,在機(jī)械、土木等結(jié)構(gòu)設(shè)計(jì)領(lǐng)域得到了廣泛的應(yīng)用。隨著復(fù)雜產(chǎn)品設(shè)計(jì)對數(shù)值計(jì)算性能要求的不斷提升,重分析方法必將在各個(gè)學(xué)科領(lǐng)域起到重要的作用。為此,該文從靜態(tài)和動態(tài)的角度出發(fā),分別對重分析理論的兩類主要方法:直接法和近似法展開了深入地討論,通過對目前主要重分析方法的發(fā)展現(xiàn)狀和主要成果的分析和研究,對未來重分析方法的發(fā)展方向提出了幾點(diǎn)建議。
[Abstract]:As a fast calculation method which can quickly estimate the modified structure according to the initial calculation results, the reanalysis method has been extensively studied in recent decades, and a series of achievements of theoretical value and engineering significance have been obtained. Civil engineering and other structural design fields have been widely used. With the increasing demand for numerical calculation performance in complex product design, the reanalysis method will play an important role in various disciplines. In this paper, two main methods of reanalysis theory, direct method and approximate method, are discussed deeply from the static and dynamic point of view. Based on the analysis and research on the development status and main achievements of the main reanalysis methods at present, some suggestions on the development direction of the reanalysis methods in the future are put forward.
