摘要

本文讨论了水下机器人阻力物理测量与仿生水下机器人阻力计算机模拟的区别。用计算流体力学方法对其水动力特性进行了建模。特别地,我们模拟了一个椭圆圆柱体和仿生机器人,并将仿真数据与机器人的实际物理测量数据进行了比较。我们的研究目标是创造一个仿生水下机器人,因此我们对最小化机器人产生的阻力感兴趣。计算流体力学仿真结果表明,该机器人的理想体阻力较低,但目前的实现仍有很大的改进空间。这也为改进仿生水下机器人的设计提供了进一步的指导。

CFD simulations and real world measurements of drag of biologically inspired underwater robot
This paper discusses the differences between physical measurements of drag of underwater robot and computer simulation of drag of biomimetically inspired underwater robot. The hydrodynamic properties are modeled with methods of computational fluid dynamics. In particular, we simulate an elliptical cylinder and the biomimetic robot and we compare simulation data with data gathered in real physical measurement of the robot. Our research is aiming to create a biomimetic underwater robot and therefore we are interested in minimizing the drag created by the robot. The results of the computational fluid dynamics simulations show that the ideal body of the robot has a low drag but its current implementation can be improved a lot. It also gives us further guidelines for improving the design of our biomimetic underwater robot.
