为了对微型仿生扑翼进行三维复合扑动时的气动力特性进行试验研究,设计了一种能实现扑翼三自由度同步扑动的综合试验平台,平台具有扑动、俯仰和扫掠三个方向的运动自由度。机翼根部安装有力/力矩传感器,可对扑动过程中机翼所受的三个方向的力和力矩进行实时测量。开发了三维扑动试验测控软件,软件可对三个微型伺服电机进行精确控制从而在机翼上实现任意形式的复合扑动。进行了三维扑动验证试验,试验结果表明,系统可以满足后续风洞试验的测控要求。
In order to test and study the aerodynamic characteristics of the micro-bionic flapping wing when the three-dimensional compound flapping occurs, a comprehensive testing platform that can achieve the flapping-wing three-degree-of-freedom flapping synchronization is designed. The platform has three flutter, pitch and sweep Direction of freedom of movement. The wing root is equipped with a force / moment sensor that measures the forces and moments in all three directions to the wing in flutter. Developed a three-dimensional flutter test measurement and control software, the software can be precisely controlled three micro-servo motor to achieve any form of compound flutter on the wing. Three-dimensional flutter verification test was carried out, the test results show that the system can meet the follow-up wind tunnel test requirements.
