Several involved factors of the damage boundary problem were shown in this paper . at the same time , the fragility was researched as a import factor and the test method with which gets the displacement fragility was firstly given . moreover , this paper apply a way to solution the fragility with fea as the base of simulation analysis of damage boundary with a computer 論文闡述了與包裝系統(tǒng)損壞邊界相關(guān)的幾個問題,并重點就產(chǎn)品易損度的確定進行了比較深入的探討,提出了測取系統(tǒng)位移易損度及其相關(guān)物理量試驗方法;給出了一種用有限元分析方法計算產(chǎn)品易損度的方法及其實現(xiàn)過程,從而為文中提出的計算機模擬分析法確定包裝系統(tǒng)損壞邊界提供了基礎(chǔ)。
