基于MATLAB与ADAMS对扑翼机构优化仿真分析

The Optimization Simulation and Analysis of Flapping Wing Mechanism on MATLAB and ADAMS

微型扑翼机具有体积小和重量轻特征,在其飞行过程中如果左右扑翼动作不能保持良好的一致性,则扑翼机将发生向一边倾斜的现象,控制其平稳飞行难度大。针对上面出现的问题,扑翼机构采用体积最适合微小化、结构最简单、最可靠的单曲柄双摇杆机构,并对此扑翼机构建立运动学和动力学方程模型。在机构设计要求和各个连杆约束条件下,利用MATLAB对其目标函数进行了优化设计。同时利用虚拟样机ADAMS建立单曲柄双摇杆机构模型,对其各杆件长度进行优化分析。经过优化该扑翼机构表明:优化后大大增强了扑翼机左右翼的运动对称性,为后期实物平稳飞行降低控制难度。

Micro flapping wing machine has small volume and light weight characteristics, in the process of its flight around if the flapping wing action can't keep a good consistency, the flapping wing machine will occur the phenomenon of tilt to one side, the control of its smooth flight is difficult. Aiming at the problems above, the flapping wing mechanism using the most suitable for small volume, structure of the simplest and most reliable single crank rocker mechanism, and the flapping wing mechanism kinematics and dynamics equation model is established. In each connecting rod mechanism design requirements and constraints, using MATLAB to its objective function is optimized design. At the same time, the single crank rocker mechanism was established based on ADAMS virtual prototype model, the length of each bar for optimization analysis. Through the optimization of the flapping wing mechanism results show that the optimized greatly enhances the left of the flapping wing flight vehicle movement symmetry, late for physical steady flight control easier.
