Zusammenfassung der Kapitel (Chapter Summaries)
Abstract: This paper examines the systems biology of rays in fish fin membranes. It describes the functional geometry of the fin membrane and presents results of calculations and measurements for the mechanics of fin rays. The ultimate goal is to understand the principles of fish fin mechanics and apply them to biomimetic technology.
Introduction: The introduction establishes the context of the study within the field of biomimetics, highlighting the importance of understanding natural systems for technological innovation. It emphasizes the success of ray-finned fishes and the lack of understanding surrounding the diversity and functionality of their fins.
Evolutionary History of Fish Fins: This section delves into the evolutionary origins of fish fins, discussing various hypotheses regarding their development from continuous fin edges to the complex structures found in modern fish. It highlights the significance of the sea lamprey genome in understanding the early evolution of vertebrates and the subsequent diversification of fin types and functions.
Mechanics of Fish Fins: This chapter details the mechanics of fish fins, focusing on the structure and function of fin rays (ceratotrichia and lepidotrichia). It explains how the arrangement of fin rays, along with the surrounding membrane, contributes to the overall efficiency of the fin as a propulsion and maneuvering system. The chapter describes the different types of soft rays in caudal fins and their role in creating a three-dimensional wing structure with anisotropic properties.
Fluid-Structure Interaction: This section analyzes the complex interplay between the fish fin and the surrounding fluid. It discusses the concept of vortex control and how fish utilize this mechanism for efficient locomotion. The chapter differentiates between productive and generative fluid-structure interaction, emphasizing the importance of the timing of body motion in relation to vortex shedding for optimal energy transfer. The work of researchers like James Liao and the implications of their findings regarding fish swimming are also discussed.
Bionic Applications and Future Research: This chapter explores the potential for applying the principles of fish fin mechanics to biomimetic engineering. It mentions ongoing research projects at Beuth University that aim to create adaptive foils based on biological designs. The section also highlights the need for advanced numerical models to simulate the complex fluid-structure interaction involved in fish locomotion and improve the design of biomimetic components.
State of Science: This section summarizes the current understanding of fish fins as highly efficient propulsion systems capable of adapting their shape to optimize performance. It underscores the unique “intelligent mechanics” inherent in biological fins, which passively react to various fluid conditions without cognitive control, serving as a foundation for further biomimetic research.
