一种两段式扑翼飞行器的设计和仿真研究
发布时间:2021-12-30 03:20
从鸟翼的结构出发,研究了鸟翼的力学和运动学,模拟了鸟翼周围气流的运动。针对扑翼机器人的皮肤,在运动学分析的基础上,得到了外翼的运动规律,并对外翼的倾斜升力运动进行了建模和分析。在建模过程中,采用有限元建模。首先,利用MATLAB软件对扑翼机构进行了数值分析。得到了理论扑翼的角速度、角加速度等图像。良好特性的结论。在ADAMS中,建立了扑翼机器人模型的虚拟样机,并对扑翼船进行了运动学建模。以10°、20°和30°的阶跃振幅为例,得到了一段时间内机翼流场的升力曲线、推力曲线、压力云图和速度云图。在Ansys软件包中,我们还建立了机翼在空中的空间模型。机翼采用不同的攻角:+3°、0°、-3°、-6°、-9°、流速为50 m/s。作用在机翼上的气流分布和载荷的关系如下获得了攻角显示气流开始脱离机翼,从而导致升力损失。
