Mechanism Design and Modeling of a Biomimetic Bluespotted Ray
摘要
Abstract
To develop an underwater propulsor with high maneuverability and stability for the purpose of search and rescue,environment monitoring,resource detecting and military reconnoitering etc,as well as considering the badly effect on aquatic organism by modern screw propeller,the bluespotted ray was selected as bionic object upon extensive investigations and analysis on various fishes.Through principle of biomimetic engineering,a high performance biomimetic bluespotted ray model was developed.Firstly,we presented a brief introduction to the live bluespotted ray.Then,a detailed analysis on mechanical design principles and methods was conducted.Finally,a coordinate system was established to determine the kinematic and hydrodynamic equations of both oscillating fin ray and undulating fin.These works provide a theoretical basis for developing a high performance underwater propulsor.The initial experimental results illustrated that： the biomimetic bluespotted ray were able to achieve no-radius turning,its body could hold a stable posture during cruising and disturb surrounding fluid less.关键词
