| description | The invention relates to an underwater manifold wave slamming mechanism analysis method considering an air cushion effect. The method comprises the following steps: carrying out model simplification on an underwater manifold; simulating a wave pool by using the simplified underwater manifold and using an SPH method; under the condition that the influence of the air cushion effect is not considered and under the condition that the influence of the air cushion effect is considered, the underwater manifold is put into a simulated wave pool under the conditions of different wave parameters, lowering speeds and underwater postures, and wave slamming force after the air cushion effect is considered is obtained; the wave slamming force with the air cushion effect considered is compared with the wave slamming force without the air cushion effect considered, and the predicted influence of the wave parameters, the lowering speed and the underwater posture on the wave slamming force is obtained. According to the method |
