摆动导杆驱动的小型旋转折叠翼动力学仿真

Dynamics Simulation of Small Rotating Folding Wing Driven by Swing Rod

通过配置旋转折叠翼可显著增加小型制导炸弹的飞行距离。为了验证旋转折叠翼的展开性能,对一种摆动导杆驱动的小型旋转折叠翼方案进行研究。应用理论力学的动能定理,得出了理想化模型的展开运动方程,并通过MATLAB进行数值求解;应用多体系统动力学理论,在ADAMS中建立了该方案的虚拟样机,通过PECE预估校正算法,仿真分析了动力学运动规律。仿真结果表明两种分析方法得出的小型旋转折叠翼展开运动规律相同;满载情况下,该方案的展开时间满足设计要求。

The rotating folding wing configuration can significantly increase the flying distance of small guided bombs.In order to verify the unfolding performance of rotating folding wing,a scheme of small rotating folding wing driven by swing rod is studied.By applying the kinetic energy theorem of theoretical mechanics,the motion equation of idealized model is obtained,and numerical calculation is carried out through MATLAB.By applying the multi-body system dynamics theory,the scheme's virtual prototype is established in ADAMS.Through PECE forecast correction algorithm,the dynamic motion rules is analyzed by simulation.The simulation results show that the motion rules of small rotating folding wing obtained by the two analytical methods are the same.In full-load case,the unfolding time of the scheme meet the design's requirement.
