温变形变结构时域有限积分建模方法研究OA北大核心CSTPCD

In this paper,we propose and implement a time-domain finite integral technique(TDFIT)for modeling thermal deformations and variable structures of any complexity.By employing a rapid 3D inter-polation technology,we simultaneously solve the deformation mapping of diverse thermoelectric mesh models and parametric surfaces.Our approach ensures the accurate integrated simulation of thermoelectric properties,arbitrary thermal distributions,and minor shape variations.The proposed method is particu-larly suitable for materials characterized by electrically large scales,non-uniform temperature changes,and deformations.This study presents a thermoelectric integrated modeling approach and a practical simula-tion tool for analyzing the electromagnetic scattering and radiation properties of radomes and aircraft under high-temperature and high-pressure conditions.
