摘要
四旋翼无人机作为新型空中作战力量,在军事与民用领域应用广泛。对于无人机来说,其机身质量是影响无人机性能的一个关键因素,文章利用Altair Inspire有限元分析软件,对无人机机身部件进行轻量化研究,以提升其灵活性与飞行性能。对无人机机身部件进行有限元分析、拓扑优化、几何重构,并采用正交试验,对影响拓扑优化结果的多种因素进行了综合考量。研究表明:该方法可实现73.9%的减重,显著降低了机身质量并保证了其力学性能,为无人机轻量化设计提供了新的理论依据与技术路径。
As a new type of aerial combat force,quadrotor drones are widely used in military and civilian fields.For drones,the fuselage mass is a critical factor affecting their performance.This study employs Altair Inspire finite element analysis software to conduct lightweight design research on drone fuselage components,aiming to enhance their maneuverability and flight perfor⁃mance.Finite element analysis,topology optimization,and geometric reconstruction were conducted on UAV fuselage components.Orthogonal experiments were employed to comprehensively evaluate multiple factors influencing the topology optimization results.The research demonstrates that this method achieves a 73.9%mass reduction while significantly improving mechanical perfor⁃mance,providing a novel theoretical basis and technical approach for lightweight drone design.
