摘要：

Potential fluid In order to meet the needs of tourism development in the South China Sea, this paper designs a heart-shaped very large floating tourism platform, which integrates the comprehensive functions of cruise ship docking and entertainment. The platform has the characteristics of low flexibility, discontinuous multi-free-surface water and complex phenomena such as water resonance. Firstly, the three-dimensional finite element model of the platform is established, and the complex vibration modes in vacuum are analyzed. It is found that the heart-shaped platform has complex vertical and torsional coupled vibration modes. Secondly, the irregular frequency and water resonance of the elastic structure of the platform are studied by using the three-dimensional frequency domain hydroelastic method based on the extended boundary integral method. The irregular frequencies of the floating body are removed through one rigid lid effectively, and the resonant points of internal free water is clearly revealed. Then, the laws of motions, elastic deformation responses and structural sectional loads are analyzed, and the effects of water resonance point and structural elastic resonance point on motions, structural deformation responses and sectional loads are investigated. Finally, the extreme load prediction is carried out, and the dangerous load conditions and dangerous structural areas are identified. © 2022 Elsevier Ltd
