This article focuses on the study of bionic wings. Based on the analysis of insect thoracic cavity structure and movement mechanism, two groups of insect flapping wings models were simulated, and unsteady aerodynamic problems were studied using computational fluid dynamics numerical simulation methods, with emphasis on computer simulation, iterative calculation equations and observation. The convergence is used to analyze the driving force curve, verify and analyze the influence of air fluid on the surface pressure and speed of the wing during the flight of the insect. Studying the influence of fluid mechanics during insect flight is of great significance to further optimize and improve existing aircraft structure forces.
