摘　　要：为探究不同材料属性柔性扑翼飞行器气动特性的变化,通过ANSYS中Fluent与Transient Structural的双向流固耦合方法,采用k-ω湍流模型,分别对三维柔性扑翼飞行器在不同材料属性下的气动特性进行数值模拟,得到了其瞬时升力、推力随翼面弹性模量的变化情况,并研究了一周期内扑翼展向流场压力分布与涡结构变化情况。研究结果表明,在一定范围内增加翼面弹性模量,对瞬时升力的提升效果并不明显,瞬时推力会随弹性模量的增加而降低。In order to investigate the changes of aerodynamic characteristics of flexible flapping wing vehicles with different material properties,the aerodynamic characteristics of three-dimensional flexible flapping wing vehicles with different material properties are numerically simulated by the two-way fluid-structure coupling method of Fluent and Transient Structural in ANSYS,using the k-ωturbulence model,respectively,and the instantaneous lifting and drag curves of the flexible flapping wing vehicles are obtained with the change of the elasticity modulus of the wing,and study the pressure distribution and vortex structure change of the spreading flow field of the flapping wing in one cycle.The results show that,within a certain range,increasing the airfoil elastic modulus does not have a significant effect on the instantaneous lift enhancement,and the instantaneous thrust will decrease with the increase of elastic modulus.
