Abstract
- Vertical cambered V-type otter boards are widely used in large and medium-sized trawlers for their good stability and adaptability to various water layers. However, limited numerical studies on the hydrodynamic performance and structural strength of this type of otter board have been published. In this study, we established the three-dimensional numerical model of the double-slotted vertical cambered V-type otter board according to its special structure and stress feature. We compare the hydrodynamic performance results of our model with those of previous experiments. Using this model, we analyzed the influence of parameters such as attack angle, aspect ratio, dihedral, and deflector angles on its hydrodynamic performance. Moreover, the structural response characteristics of the otter board under typical working conditions were studied. We believe our results will provide theoretical reference for the structural design and optimization of the vertical cambered V-type otter board.
