| description | The dynamics of the gravitational lifting system of the deep sea mining industry is demonstrated in this article. A simplified dynamic model is obtained when gravity, buoyancy and drag force are the major concerns. By quantitative analysis, different variables like bucket size, distribution distance, and filling rate are considered to measure their influence on lifting speed and production rate, which ends up with that the most influential factor is the bucket size, and it has a positive correlation with both the two targets: lifting speed and production rate. Due to the breaking strength of the cable wire rope, a feasible design of such a lifting system should take the tension force into consideration. Hence, the feasibility is also examined and a conclusion is summarized that a combination of the bucket size and the distribution distance should be optimized according to the concrete working conditions. |
