doi:10.16182/j.issn1004731x.joss.18-0409

Abstract

Abstract: Focus on the rapid physical exertion and the poor flexibility of diving propeller vehicle, a wearable diving propeller equipped with buoyancy control devices is proposed, and the position of the propeller in the device is optimized. The human body structure is regarded as a rigid body to establish a spatial 6-degree-of-freedom motion equation, and its surrounding hydrodynamic performance is analyzed. The hydrodynamic parameters in the model are obtained based on the FLUENT. The propeller position optimization model based on the minimum external force of rectilinear diving and slewing motions is established. The optimization results demonstrate that the optimized propeller position can effectively reduce the vertical diving speed and maintain a steady diving state.

Key words: diving propeller vehicle, hydrodynamic parameters, added mass, dynamic simulation, positional optimization
