摘要
为不断优化仿生蝴蝶微型飞行器性能,深入探究结构多尺度优化设计,以仿生蝴蝶翅膀结构为核心,依托整体启动布局和微观材料的特征,创建多尺度耦合优化模型。结果表明,在模拟数值和风洞实验过后,优化后的飞行器升阻比有明显提升,振动频率也有相应减少,结构轻量化程度也有提高,尤其在复杂气流环境下,显著增强稳定性,从而为微型飞行器设计提供跨尺度协同优化提供全新的方法。
In order to continuously optimize the performance of biomimetic butterfly micro air vehicles and deeply explore the multi-scale optimization design of structures,a multi-scale coupled optimization model is created with the biomimetic butterfly wing structure as the core,relying on the characteristics of the overall start-up layout and micro materials.The results showed that after simulation and wind tunnel experiments,the optimized lift to drag ratio of the aircraft was significantly improved,the vibration frequency was correspondingly reduced,and the degree of structural lightweighting was also improved.Especially in complex airflow environments,the stability was significantly enhanced,providing a new method for cross scale collaborative optimization of micro aircraft design.
