Digital Simulation Method for Electromagnetic-Thermal-Mechanical Environment of Aerospace Products

Addressing the deficiencies in the typical digital simulation methods for aerospace products in terms of lacking a comprehensive multi-physics coupling framework and incomplete consideration of physical fields and relevant simulation elements, a digital simulation method is proposed for the electromagnetic-thermal-mechanical typical environmental conditions of aerospace products. Firstly, an analysis of the multi-physics field, computational elements, and coupling relationships of aerospace products is conducted to clarify the simulation elements. Secondly, the digital simulation process of the electromagnetic-thermal-mechanical coupling environment is outlined, and a method for digital modeling of multi-physics fields is presented based on sequential coupling. Finally, the proposed method is applied to a printed circuit board used in a certain aerospace product to validate the feasibility and effectiveness of the framework proposed in this study, providing reference for the testing, identification, and improvement of aerospace products.
