The motion behavior of butterflies is complex and dynamic, involving multiple factors such as aerodynamics, environmental variables (e.g., wind speed, temperature), biological driving mechanisms (e.g., wingbeat frequency, wing flapping angle), and neural control over flight direction. By collecting butterfly motion data, including position trajectories, flight speed, and wing amplitude, and integrating them with data modeling techniques, a precise butterfly motion simulation system can be constructed.
After modeling the motion behavior of butterflies, Computational Fluid Dynamics (CFD) can be further utilized for a more in-depth simulation to analyze the aerodynamic characteristics of butterfly wings in the air. This process is primarily used to study the interactions between the wings and the surrounding airflow, including key factors such as lift, drag, vortex formation, and airflow patterns.
To further investigate the aerodynamic characteristics of butterfly wings and their impact on flight performance, high-precision 3D modeling of the wing’s microscopic structure is conducted, followed by 3D printing to create physical prototypes. This process not only allows for intuitive observation and analysis of the intricate wing structure but also facilitates wind tunnel testing and aerodynamic experiments to verify the effects of different microstructures on airflow control.
To enhance wind tunnel experiments, a small-scale wind tunnel was self-constructed during the research process to enable precise measurements and experimental validation of the aerodynamic characteristics of butterfly wings. This compact wind tunnel is designed to generate stable and adjustable airflow in a controlled environment, making the experiments more accurate and efficient. During testing, the wind speed can be adjusted to simulate different flight conditions, and smoke visualization is used to analyze lift, drag, vortex structures, and airflow distribution. This self-built wind tunnel provides essential support for the research.
