The simulation of paddle based on workbench

For the complication of underwater environment and the cumbersome of calculation process, many parameters are difficult to obtain in the underwater vehicle research. In general, the only way to get parameters is doing experiments. In this paper, achieving parameters through simulation without experiments was put forward. We simulated the paddle and its water surrounding with ANSYS software. The hydrodynamic force was put on the paddle as fluid-structure interaction. Then, based on the characteristic of independence between the hydrodynamic force and motion history, we analysed the paddle by every 5° with static analysis method. At last, it would be used in our control system after collection.
