摘要: 本研究针对航空铝合金表面复合漆层高精度去除需求，建立连续–纳秒复合激光与气流辅助耦合的有限元模型。基于有限元仿真分析法构建包含激光热源、气固耦合传热及热弹性力学的多物理场模型，重点分析不同能量密度下的温度梯度演化规律与热应力分布特征。揭示复合激光除漆的机理，阐明激光参数与热力耦合响应的关联机制，为复合激光除漆工艺优化提供理论依据。
Abstract: A finite element model of continuous nanosecond composite laser coupled with air flow assisted coupling was established to remove the high layer accuracy of composite coatings for aerospace aluminum alloys. A multi-physics model including laser heat source, gas-solid coupled heat transfer and thermoelasticity was constructed based on finite element simulation analysis. The temperature gradient evolution law and thermal stress distribution characteristics under different energy densities were analyzed. The mechanism of composite laser paint removal was revealed, and the correlation mechanism between laser parameters and thermal coupling response was elucidated, which provided theoretical basis for the optimization of composite laser paint removal process.
