Abstract

The invention discloses a hull head flare-out slamming parallel computing method based on a three-dimensional model. The hull head flare-out slamming parallel computing method comprises the followingsteps that S1, dispersing a hull shell within the hull head outwards-floating slamming range into a plurality of spatial quadrangles through a computer terminal; S2, calculating the vertex attribute corresponding to each vertex of each spatial quadrangle; S3, dividing each spatial quadrangle into two corresponding triangles, and determining a plurality of calculation points needing parameter calculation in each triangle; S4, calculating a first design parameter index corresponding to each vertex and a second design parameter index corresponding to each calculation point based on each vertex attribute; And S5, according to a preset rendering method, displaying each vertex, each calculation point and the corresponding first design parameter index and the corresponding second design parameterindex on a computer terminal screen, the principle is simple, the calculation speed is high, and various design parameters of the ship can be visually displayed.

Description

technical field [0001] The invention relates to a calculation method for hull bow slamming, in particular to a parallel calculation method for hull bow slamming based on a three-dimensional model. Background technique [0002] Slamming is a violent impact phenomenon between waves and the hull, which mainly occurs at the bow. The slamming is caused by the ship's severe pitching in rough sea conditions, the bow of the ship is out of the water, and it enters the water at a relatively large relative speed. The slamming makes the bow of the hull suffer a lot of impact pressure, and the impact pressure can often cause serious deformation or damage to the structure of the bow of the hull, and cause a large longitudinal bending moment of the hull. [0003] The traditional hull bow slamming calculation method relies on the designer to manually measure the local waterline angle, bow impact angle and other data at different positions in the slamming area, and calculate the bow slammin...
