不确定性因素结构的有限元建模与确认
Finite Element Modeling and Validating of Structural Uncertainty Factors
摘要
Abstract
Finite element modeling and validating for structural uncertainty are necessary for the wide existence of the uncertainties in the assemblage process of engineering structures. The multi-case virtual modal tests were done for a set of composite beam structures. The identification and quantification of uncertainty parameters and the model validation were performed via a validated frame of the model. This study shows the difference between the finite element models with and without the consideration of the structural uncertainties, and has provided a reference for similar engineering cases.关键词
