stability of numerical integration

基本解釋

It is shown that the numerical stability condition of the integration formula is same as that of the central difference method.
本文在時(shí)域有限元離散的基礎(chǔ)上，導(dǎo)出了集中質(zhì)量阻尼彈性結(jié)構(gòu)動(dòng)力模型的顯式差分法，數(shù)值穩(wěn)定條件同中心差分法。
The problem of stability in the numerical integration schemes of nonlinear dynamic analysis of structures is discussed by using matrix and norm theory on a rigorous and complete basis in this paper.
本文在嚴(yán)格、完整的基礎(chǔ)上，利用矩陣范數(shù)理論研究了結(jié)構(gòu)非線性動(dòng)力分析中數(shù)值積分格式的穩(wěn)定性問題，給出了判別單自由度非線性動(dòng)力方程積分格式穩(wěn)定性的一般數(shù)學(xué)準(zhǔn)則。
The ordinary numerical integration method has only been adopted for the analysis of the stability of steel members so far due to its limitations of handling technology and its slow computative speed.
目前，數(shù)值積分法在結(jié)構(gòu)分析中的應(yīng)用本質(zhì)上沒有突破構(gòu)件的范疇，其主要原因是技術(shù)處理存在局限性，計(jì)算速度難以使人接受。
