| 摘 要： | 文中提出了一种引入迁移学习的形变重构方法，并用某无人机机翼进行了实验验证。该方法首先利用模态法获取大量的仿真源数据，并对实际机翼进行测试，获得少量的目标数据，然后利用迁移学习算法将目标数据迁移到源数据中，使得重构的位移值更加接近实际测量值。结果表明，该方法大幅提升了机翼蒙皮天线在实际工作环境中的形变重构精度。

| Abstract: | A deformation reconstruction method that introduces transfer learning is proposed and verified by experiment with an unmanned air vehicle (UAV) wing in this paper. A large amount of simulation source data are obtained by modal method first and a small amount of target data are obtained by test of the actual wing. Then the target data are transferred to the source data by the transfer learning algorithm, so that the reconstructed displacement value is closer to the measured value. The results show that this method has greatly improved the deformation reconstruction accuracy of the wing in the actual work environment. |
