英文摘要Laser identification of aircraft in service is beneficial for collecting environmental information and rapidly avoiding risks. In this paper, the thermal-mechanical response of honeycomb sandwich structures irradiated by the high-energy continues-wave laser is investigated. A physics-guided neural network method, based on the multivariate thermal-mechanical response is developed to solve the laser identification problems, especially the laser multi-parameter identification in complex oblique incidence. The dataset is built based on three thermalmechanical characteristic parameters: the temperature variation rate, the generalized temperature gradient, and thermal strain. These parameters better characterize the laser irradiation process and work in concert with the physics-guided neural network to improve inversion accuracy. In this work, three parameters of the laser are simultaneously inverted: angle of incidence, laser diameter and laser power. The proposed method is verified through simulation analysis and laser irradiation experiments. The effects of the physics-guided loss function and multivariate information fusion are discussed, and it is found that the results based on the proposed method are significantly better than those based on the non-physics guided method. Additionally, the results from thermalmechanical information fusion are superior to those obtained from the single temperature response.
