摘要
对电动飞机进行轻量化设计,能够增加电动飞机的有效载荷或延长续航时间。以电动飞机的电池舱支撑框结构为研究对象,基于拓扑优化、模态分析以及复合材料层合板铺层优化技术,利用HyperWorks软件分别对电动飞机的电池舱支撑框结构进行单一材料的结构拓扑优化、模态分析、基于模态分析的拓扑优化以及复合材料层合板的铺层优化,并对各优化后的模型进行了静力分析,并验证了优化后结构的有效性。从而实现了对电池舱支撑框的轻量化设计。
Lightweight design of electric aircraft can increase the payload or extend the flying range of electric aircraft.The battery compartment support frame structure of electric aircraft was selected as the research object.By using HyperWorks,the optimization process of the battery compartment support frame structure was performed with the aid of structural topological optimization,modal analysis and topology for Isotropic material,respectively.In addition,the optimization and lay-up optimization of composite laminates were verified.,Each optimized model was analyzed by statics.Therefore,the lightweight and optimization design of the battery compartment support frame are realized.
