摘要
Abstract
A new type of petal-shaped capsule robot is proposed, which can improve the driving performance. The convergent wedge-like gaps are formed between the surface of four eccentric tiles and the inner pipe wall, and multiple wedge effects happens to the fluid and the direction of fluid flow is changed when it flows around the four convergent wedge-like gaps. According to the fluid dynamic model, the analytical solution of hydrodynamic pressure and steady state velocity of the robot are obtained. Numerical simulation method is employed to visualization analysis of the flow characteristics of the robot. Theoretical and experimental results show that both fluid dynamic pressure and swimming speed of the petal-shaped capsule robot are larger. Thus, the petal-shaped capsule robot has better comprehensive performance.关键词
