Research on Optimization of Kinematic Parameters of Pectoral Fin

Abstract:

Since the propulsion performance of fish pectoral fin is directly related to its kinematic parameters, for improving the propulsion performance of pectoral fin, the kinematic model of propulsion motion of pectoral fin was established, the hydrodynamic force acted on the pectoral fin during propulsion motion was calculated and the mathematic model which optimized the propulsion performance of pectoral fin was established. Then MATLAB was used to write the genetic algorithm program which is used to get the optimal solution of kinematic parameters of pectoral fin. Finally, the simulation analysis of the propulsion performance of pectoral fin was developed. From the simulation result, it can be got that the optimal model established and the optimal algorithm adopted can play an important role in improving the propulsion performance of pectoral fin. Therefore, the optimal analysis developed in this paper is reasonable and effective as well as provides theoretical reference to the research on the bionic pectoral fin and the new underwater maneuvering vehicle.
