摘要
利用有限元方法,在I-DEAS中对电子产品结构进行瞬态响应分析。分析时使用等效均方根值的瞬态激励来替代加速度功率谱密度激励。
Response analysis of the structure of a electronic product was applied in I-DEAS with Finite Element Method. With the equivalent root mean square value of an acceleration Power Spectral Density excitation, transient excitation was used in the response analysis.
