摘 要: 游艇横摇严重影响船舶的稳定性和安全性,同时也降低了乘坐的舒适性,因此对船体进行减摇控制历来受到设计与研究人员的广泛关注。传统的减摇方式如减摇鳍等难以在复杂的航行条件下得到满意的稳定控制效果。尝试将电磁分支电路阻尼动力吸振器应用于游艇的减摇控制中,以改进船舶的稳定性与安全性。建立了游艇与电磁分支电路阻尼吸振器的耦合动力学模型,采用微粒群优化算法对电磁分支电路阻尼吸振器的工作参数进行了优化设计。基于优化得到的参数进行了游艇减摇仿真分析,结果表明电磁分支电路阻尼吸振器能够获得较好的减摇效果。 Traditional treatment by using antiroll fins to reduce the roll of yachts, sometimes, cannot well satisfy the safety requirement in some violent sailing conditions. An electromagnetic shunt damping absorber was introduced to improve the stability and safety of the yacht. The governing equation of a yacht coupled with such an absorber was derived. The dynamic parameters of the absorber were determined by using particle swarm optimization algorithm. The numerical simulation was conducted based on optimal parameters, and the results show that the absorber presented can well reduce the yacht roll.
