Towards a Conceptual Model of a Bio-Robotic AUV: Pectoral Fin Hydrodynamics
نویسندگان
چکیده
Numerical simulations have been used to examine the performance of flapping foils. It is envisioned that these flapping foils will be employed as pectoral fins in a bio-robotic AUV (BAUV) and a detailed parametrization of the hydrodynamic performance of these foils will allow for the development of a high-fidelity dynamical model of the BAUV. In the long term, it is expected that this dynamical model will provide a rational basis for the design, sizing and placement of these fins. In the current paper, we describe a sequence of simulations that explore the effect of pitch-bias angle on the hydrodynamic performance of a 2D flapping foils. In another sequence of simulations, we have examined the effect of foil aspect ratio on its performance and results relating to this study are also included.

متن کاملLow-dimensional models and performance scaling of a highly deformable fish pectoral fin
The hydrodynamics of a highly deformable fish pectoral fin used by a bluegill sunfish (Lepomis macrochirus) during steady forward swimming are examined in detail. Lowdimensional models of the fin gait based on proper orthogonal decomposition (POD) are developed, and these are subjected to analysis using an incompressible Navier– Stokes flow solver. The approach adopted here is primarily motivat...

This paper describes the modeling and control development of a bio-inspired unmanned underwater vehicle (UUV) propelled by four pectoral fins. Based on both computational fluid dynamics (CFD) and experimental fin data, we develop a UUV model that focuses on an accurate representation of the fin-generated forces. Models of these forces span a range of controllable fin parameters, as well as take...
متن کاملA review on robotic fish enabled by ionic polymer–metal composite artificial muscles
A novel actuating material, which is lightweight, soft, and capable of generating large flapping motion under electrical stimuli, is highly desirable to build energy-efficient and maneuverable bio-inspired underwater robots. Ionic polymer-metal composites are important category of electroactive polymers, since they can generate large bending motions under low actuation voltages. IPMCs are ideal...
