摘要
采用两种分析方法对某无人机的机翼折叠/展开运动特性进行研究。建立该机构运动的微分方程,用龙格-库塔法进行求解;用M ATLAB非线性优化工具包对扭转弹簧的主要参数进行了优化设计;利用多体动力学分析软件进行机构的运动仿真分析。两种方法得到分析结果与实验吻合很好。
The movement characteristics of UAV folding/unfolding wings are studied by two methods. The mathematical model for the framework is established and solved by Runge-Kutta method. Parameters of torsional spring are optimized by the nonlinear optimal toolbox in MATLAB. The movement of folding/unfolding wings is simulated using a mechanism dynamics analysis software. Two methods are proved to be effective.
