摘　　要：智能微型导弹可以通过控制可变形智能弹翼结构改变飞行状态,满足作战需求。针对此类可变形智能小翼结构,本文以压电纤维复合材料(Macro Fiber Composite,MFC)作为驱动器,通过使用MFC碳纤维复合材料悬臂梁仿真和试验相结合的方法验证压电复合材料的驱动性能。随后,设计了MFC复合材料小翼驱动机构并进行驱动试验,验证了所设计的MFC驱动智能小翼变形方案的可行性。在此基础上,研究了智能小翼复合材料蒙皮铺层设计对小翼压电驱动性能的影响。结果表明,增大智能小翼蒙皮45°铺层占比、减小0°铺层占比,或将45°铺层置于蒙皮表层、0°铺层置于蒙皮芯层时,有利于智能小翼驱动性能提升。By controlling deformable intelligent missile winglets,miniature missiles with smart winglets can change the flight state to meet the operational requirements.For this kind of deformable smart winglet structure,this paper takes the macro fiber composite(MFC)as the actuator to drive composite cantilever beams,and verifies the driving performance of MFC by the combination of simulation and experiment.Subsequently,the driving mechanism of composite winglet with MFC is designed and tested,which can verify the feasibility of the design scheme.On this basis,the influence of smart winglet composite skin ply design on driving capability is investigated in detail.The results show that driving capability of MFC can be improved by increasing 45°ply ratio and decreasing 0°ply ratio,or placing 45°ply on the surfaces and 0°ply in the middle plane of skin.
