基于响应面方法的支架结构模型修正研究
Study on Frame Model Updating Based on Response Surface Method
摘要
Abstract
A frame structure model is employed to study how to reduce the errors in finite element modeling. Three elastic moduli and three density parameters are selected as design parameters. The central composite design method is used to construct the sample space. The parameters to be updated are selected with the use of significance analysis. The second order polynomials for modal frequency and parameters updating are established by means of linear regression method. The finite element model of the frame is updated according to the result of the experimental modal analysis. The modal frequency updated by the response surface method is in good agreement with the result of experiment analysis. The advantage of this method is that it is not necessary to call the finite element model repeatedly. As a result, the updating efficiency is greatly improved. The response surface method for model updating is effective and has engineering practicability.关键词
