Performance analysis derivative based updating method

The low-order frequency errors in the simulation model are less than 5%, the high-order errors are less than 10%, and the modal confidence MAC values are above 0.8.The modal frequency and mode shape are closer to the experimental modal frequency and mode shape, respectively.Among them, honeycomb sandwich panels are widely used.

This strongly affects the reliability of finite element analysis.For these reasons, it is quite difficult to establish an accurate and reasonable finite element model.There is error between finite element analysis results and experimental values.

Finite element modelling consists of numerous theoretical assumptions, model simplification, distortion of connection conditions, and other factors.
