摘要
利用平面多闭环连杆机构，提出一种可变形机翼结构，并对该结构进行数学建模，利用结构数学模型，在Matlab中进行了机构的运动轨迹仿真分析。为了验证机构曲率调节能力及气动特性，建立了机构的三维模型，进行了运动学仿真及空气动力学仿真分析。为了获得更好的气动特性，基于传统人工鱼群优化算法，提出一种改进的人工鱼群优化算法，利用经典优化算法测试函数测试了该算法的性能。采用该优化算法对可变形机翼进行结构优化。在理论研究的基础上，加工了实验样机，并进行了相关实验测试。
Abstract
A morphing wing structure is proposed by using planar multi-closed loop linkage. The mathematical model of the structure is established. The mechanism trajectory is simulated and analyzed in Matlab by using the structural mathematical model. In order to verify the curvature adjustment ability and aerodynamic characteristics of the mechanism， a three-dimensional model of the mechanism is established， and the kinematics simulation and aerodynamics simulation analysis are carried out. In order to obtain better aerodynamic characteristics， an improved artificial fish swarm optimization algorithm is proposed based on the traditional artificial fish swarm optimization algorithm. The performance of the algorithm is tested by the classical optimization algorithm test functions. The optimization algorithm is used to optimize the morphing wing structure. On the basis of theoretical research， the experimental prototype is processed and the related experimental tests are carried out.
