。在这项研究中，提出了一种用于昆虫翅膀特征变形的计算流固耦合（FSI）框架。所提出的框架由使用结构化壳有限元网格的像素机翼模型、使用代数分裂的整体 FSI 整体方程的投影方法以及用于测量模型和实际昆虫飞行之间动态相似性的 FSI 动态相似律组成。结果表明，所提出的框架可以直接模拟由 FSI 引起的昆虫翅膀的被动羽化和拱度，其幅度非常接近实际昆虫的幅度。
. In this study, a computational fluid–structure interaction (FSI) framework for characteristic deformations in insect’s wings is proposed. The proposed framework consists of a pixel wing model using a structured shell finite element mesh, a projection method for the monolithic FSI monolithic equations using an algebraic splitting, and the FSI dynamic similarity law to measure dynamic similarity between model’s and actual insect’s flights. It is shown that the proposed framework can directly simulate passive feathering and cambering in insect’s wings caused by the FSI, whose magnitudes are very close to those of actual insects.
