simultaneous perturbationとは 意味・読み方・使い方

The sensitivity analysis system 1 comprises a means to find the sensitivity of an element rigidity matrix according to central finite difference approximation which gives the amount of variations of a design parameter to the element rigidity matrix and has the secondary accuracy, and a means to find a series of simultaneous equations of finite element method by perturbation method using this found sensitivity.例文帳に追加

感度解析システム１は、設計パラメータの変動量を要素剛性マトリクスに与えて２次の正確性がある中心有限差分法近似により要素剛性マトリクスの感度を求める手段と、この求められた感度を用いて有限要素法の一連の連立方程式を摂動法により求める手段を備える。 - 特許庁
