摘　　要：旋翼无人飞行器具有垂直起降/着陆、可悬停、机动性好及结构简单等多种优点,无论是在军事领域还是民用领域,都有非常广泛的应用价值。文中采用Abaqus建立了某四旋翼无人飞行器的力学仿真模型。基于所建立的力学仿真模型,分析了该无人飞行器在旋翼升力、风载荷和降落冲击等工况下结构的强度和刚度响应,得到了相应的变形和应力云图。计算结果表明,该旋翼飞行器的结构设计满足总体设计要求。Rotor unmanned aerial vehicle（ UAV） has wide applications in military and civil fields due to its merits such as vertical taking off and landing,hovering ability,good maneuverability and simplified structure.In this paper the mechanical simulation model of a quad-rotor UAV is established. Based on the model,the strength and stiffness responses of the UAV structure under the conditions of rotor lift,wind load and landing impact are analyzed and the corresponding contours of deformation and stress are obtained. The results show that the structure design of this UAV satisfies the requirements of system design.
