Dynamics analysis of wave-driven unmanned surface vehicle in longitudinal profile

SUMMARY Fossil fuel sources are well suited to fulfill the energy needs of human beings. Unfortunately, there are some limitations and disadvantages pertaining to fossil fuels, some of which are drastic. The main issues are: firstly, there is a finite supply of these fuels, eventually this supply will be exhausted; secondly, burning fossil fuels contributes to global warming, leading to disastrous consequences for the environment and the health of humans. Switching to renewable energy sources is the viable solution to the aforementioned issues. Robots bring numerous benefits in a wide variety of applications. Introducing robots to production environments and other applications results in a remarkable improvement in terms of productivity and efficiency. In this paper, the integration between robots and renewable energy sources is discussed. In other words, two main points are investigated: (1) how can renewable energy be a viable source of energy for robots and (2) how can the renewable energy industry benefit from utilizing robots in the execution of renewable energy-related tasks. Some of the recent developments concerning the integration between robots and renewable energy are reviewed. In addition, more opportunities and expected advancements are also discussed.

Wave-driven unmanned surface vehicle (WUSV) is a new concept marine robot drived by wave energy and solar energy, very suitable for the observing vast oceans with incomparable endurance. Firstly, the multibody system of WUSV is described based on D-H approach and the velocity and position of each moving part in WUSV are represented. Then, the driving principle is analyzed and the WUSV dynamic model in three dimension is established by lagrangian mechanics. Finally, we perform the motion simulation of WUSV under certain sea conditions. These tasks provide the theoretical foundation for further study on the WUSV motion control and efficiency analysis.

“…Tian et al [16,17] used the D-H method to establish a motion equation and analyze the influence of wave height, wave period, and maximum limited angle on motion efficiency. Li [18] used a dynamic model to simulate the influence of umbilical length and wing number, which provide the basis for parameter optimization. In addition, he simulated the speed under first-and third-level sea conditions and the survivability under ninth-level sea conditions.…”

To study the optimal design of Wave Glider parameters in the wave environment of the Northwest Pacific Ocean, the North Indian Ocean, and the South China Sea, the average velocity of a Wave Glider was taken as the evaluation criterion. Wave reanalysis data from ERA5 were used to classify the mean wave height and period into five types by the K-means clustering method. In addition, a dynamic model was used to simulate the influence of umbilical length, airfoil, and maximum limited angle on the velocity of the Wave Glider under the five types of wave element. The force of the wings was simulated using FLUENT as the model input. The simulation results show that (1) 7 m is the most suitable umbilical length; (2) a smaller relative thickness should be selected in perfect conditions; and (3) for the first type of wave element, 15° is the best choice for the maximum limited angle, and 20° is preferred for the second, third, and fourth types, while 25° is preferred for the fifth type.
