【摘要】：研究了考慮不確定性因素的有限元屈曲模型驗證和確認方法,提出了不確定參數(shù)選擇的相關性和敏度分析方法以及基于面積度量的模型評估方法.針對化銑整體壁板,開展了有限元屈曲模型驗證研究,首先利用8件試驗件,獲得了壁板屈曲載荷的試驗值,然后依據(jù)試驗加載情況,建立了考慮試驗臺的壁板有限元模型,最后利用面積度量方法對有限元模型進行了驗證和確認.本文的模型驗證和確認方法可為其他工程結構開展類似的工作提供借鑒.
[Abstract]:The validation and confirmation method of finite element buckling model considering uncertain factors is studied. The correlation and sensitivity analysis method of uncertain parameter selection and the method of model evaluation based on area metric are proposed. The finite element buckling model verification research was carried out for the whole wall plate of chemical milling. Firstly, the buckling load test value of the wall plate was obtained by using 8 pieces of test pieces, and then the finite element model of the wall plate considering the test bed was established according to the experimental loading condition. Finally, the finite element model is validated and confirmed by the area measurement method. The model verification and validation method in this paper can be used for other engineering structures to carry out similar work.
