一種兩段式撲翼飛行器的設計和仿真研究
發(fā)布時間:2021-12-30 03:20
從鳥翼的結構出發(fā),研究了鳥翼的力學和運動學,模擬了鳥翼周圍氣流的運動。針對撲翼機器人的皮膚,在運動學分析的基礎上,得到了外翼的運動規(guī)律,并對外翼的傾斜升力運動進行了建模和分析。在建模過程中,采用有限元建模。首先,利用MATLAB軟件對撲翼機構進行了數(shù)值分析。得到了理論撲翼的角速度、角加速度等圖像。良好特性的結論。在ADAMS中,建立了撲翼機器人模型的虛擬樣機,并對撲翼船進行了運動學建模。以10°、20°和30°的階躍振幅為例,得到了一段時間內(nèi)機翼流場的升力曲線、推力曲線、壓力云圖和速度云圖。在Ansys軟件包中,我們還建立了機翼在空中的空間模型。機翼采用不同的攻角:+3°、0°、-3°、-6°、-9°、流速為50 m/s。作用在機翼上的氣流分布和載荷的關系如下獲得了攻角顯示氣流開始脫離機翼,從而導致升力損失。
