- Abstract
Study on the kinetic & kinematic mechanisms of fish-like swimming is of cardinal significance for increasing needs of bionic technologies. Therefore, an auto-swimming robotic fish model was established with a flexible body and muscular self-propelling force, involving the interactions between fish-body internal forces, fish-body motions and surrounding fluid dynamics. Then, respectively, the effects of different-length tail fins, different tail elasticities and different muscular self-propelling force densities on the robotic fish's straight-line auto-swimming state were numerically simulated respectively. The hydrodynamics and kinematics of the auto-swimming robotic fish are analysed to reveal the key factors on the cruising velocity and clarify the related mechanisms. The key factors influence on swimming efficiency is shown by analysis of hydrodynamic performance.
