Wing deformation capture with simulation is a mixed experimental-numerical approach whereby the wing deformation during flapping is captured using high-speed cameras and used as an input for the numerical solver. This is an alternative approach compared to pure experiment or full fluid structure interaction simulation. This study is an update to the previous paper by Tay et al., which aims to address the previous limitations. We show through thrust and vorticity contour plots that this approach can simulate Flapping Micro Aerial Vehiclex (FMAVs) with reasonable accuracy. Next, we use this approach to explain the thrust improvement when an additional rib is added to the original membrane wing, which is due to longer duration for the new wing to open during the fling stage. Lastly, by decreasing the number of points and frames per cycle on the wing, we can simplify and shorten the digitization process. These results show that this approach is an accurate and practical alternative which can be applied to general bio-inspired research.

翼展变形捕捉在微型飞行器仿真中的应用与改进

带有模拟的机翼变形捕获是一种混合实验-数字方法,利用高速相机捕获扑翼过程中的机翼变形,并将其用作数值解算器的输入。与纯实验或完整流体结构相互作用模拟相比,这是另一种方法。这项研究是对Tay等人先前论文的更新,目的是解决以前的局限性。我们通过推力和涡度等高线图表明,该方法可以合理合理地模拟扑翼微型飞行器(FMAV)。接下来,我们使用这种方法来说明当在原始膜翼上增加一条肋时的推力改进,这是由于新翼在下垂阶段打开所需的时间更长。最后,通过减少机翼每个周期的点数和帧数,我们可以简化和缩短数字化过程。这些结果表明,这种方法是一种准确实用的替代方法,可以应用于一般的生物启发性研究。
