蝶型はばたきロボットの飛翔データに基づくCFD解析

抄録

For flapping Robot, the index of the fuselage design and the attitude control mechanism are not clarified. Therefore, regarding attitude control of a flapping robot, it is desirable to obtain the lift in flight,in order to clarify the effects of the above-mentioned differences in structural characteristics on flight. In this study, we analyze the flight data of an Flapping robot using a CFD analysis system capable of fluid-structure interaction based on a CAD-based model, and obtain the lift, drag, and pitching moment. In addition, about posture change due to the difference in the structral characterisetics of a flapping robot,we investigate the effects on the lift, drag and pitching moment by difference of the wing down stroke and the upstroke. As a result of the analysis, it was found that lift, drag, and pitching moment change depending on the flapping neutral angle.
