【摘要】 结构有限元分析模型计算的结构响应与实测响应之间不可避免地存在一定偏差。利用结构现场实测的响应信息修正其结构有限元分析模型,使得修正后结构有限元模型计算的响应值与试验值趋于一致,此过程即为结构有限元模型修正。本文对结构动力模型修正和静力模型修正的一般理论及其进展进行了综述,讨论了有限元模型修正中的若干重要技术问题。更多还原

【Abstract】 Considerable discrepancies exist between predictions from a structural finite element analysis model and experimental results of a laboratory model when the two are compared.The updating of the finite element model of structural is that the revised structure makes finite element model of the response in line with the experimental data,by using the measured response information of the structure at the scene.This paper presents the general theory and recent development about model updating of dynamics and statics and discusses a number of important technical issues in the finite element model updating.更多还原
