ランダム応答解析の例題
始めに 本記事では、非常に簡易的なランダム応答解析のモデルを提示します。 100x100x1mm の板の真ん中をべこべこと力 (FORCE) で押すだけです。 本ランダム応答解析では、荷重ー周波数の関係が PSD-周波数の関係で与えられているものとします。 そのため、ランダム応答解析が参照する周波数応答解析サブケースでは、(計算範囲の) 全周波数に単位荷重 1N を与えて、ランダム応答サブケースにて、PSD-周波数の関係を与えることにします。 入力ルール まずサブケースセクションですが、ランダム応答解析は、周波数応答解析を元に行われるため、かならず周波数応答のサブケースが必要になります。本記事では、周波数応答に関する部分は割愛します。…
