摘要
变体飞行器在不同的飞行任务或者同一任务的不同任务阶段,通过改变其气动外形来达到最优化的飞行效能,是飞行器设计的一个重要发展方向。伸缩翼设计是飞行器重要的变形方案之一。为了提高变体飞行器伸缩翼面设计的准确性和开发效率,采用联合仿真方法来辅助设计受到越来越多的重视。其方法可以在设计阶段用于验证参数对伸缩翼性能的影响。利用机械动力学分析软件ADAMS和控制仿真软件Simulink,分别建立飞行器伸缩翼的机械动力学模型和控制器模型,对不同材料翼面的影响进行仿真验证。将仿真结果与试验数据进行对比,验证此方法的可行性,并为后续的结构优化设计提供基础。
Morphing aircraft can achieve better performance by changing the aerodynamic shape in different flying tasks or various tasks of the same task stage.Telescopic wings are one of the important deformation schemes for aircraft.In order to improving design accuracy and development efficiency,the co-simulation approach has been paid great attention recently.The co-simulation method can verify the influence of parameters on the performance of Telescopic wings during the design phase.Using ADAMS and Simulink,a comprehensive analysis and simulation mechatronic model had been established to study the kinematic and the dynamic characteristics.To meet the standards of real-time deployment of the deformation mechanism,the main parameters of the deformation wing mechanism were simulated and ameliorated.The simulation experimenthas verified the feasibility of the proposed method and provide a foundation for structural optimization design.
