stability of numerical integration

基本解释

It is shown that the numerical stability condition of the integration formula is same as that of the central difference method.
本文在時域有限元離散的基礎上，導出了集中質量阻尼彈性結搆動力模型的顯式差分法，數值穩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.
本文在嚴格、完整的基礎上，利用矩陣範數理論研究了結搆非線性動力分析中數值積分格式的穩定性問題，給出了判別單自由度非線性動力方程積分格式穩定性的一般數學準則。
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，數值積分法在結搆分析中的應用本質上沒有突破搆件的範疇，其主要原因是技術処理存在侷限性，計算速度難以使人接受。
