摘要
以响应面有限元模型修正方法为基础,结合软件MATLAB和ANSYS的集成实现了结构模型修正。以钢架结构为例,利用响应面有限元模型修正方法及所编制的工具箱,以实测模态数据为依据,修正了钢架的有限元模型。修正结果表明,有限元模型计算结果与实测结果之间的误差明显减小。
Response surface based finite element model(FEM) updating is studied.A finite element updating toolbox was developed using MATLAB as the development platform.The design of function and the interface were described.ANSYS was integrated with updating modules implemented on MATLAB using the parametric design language.The updating method and the toolbox were employed to update the FEM of a steel frame using experimental modal data.The result shows that the method is workable and the toolbox is convenient and feasible.
