摘要
风力助推转子作为一种主动式船舶节能装备,其外筒的重量与强度直接关系着风力助推转子系统的节能效益与安全性能。因此,本文针对风力助推转子复合材料外筒结构,开展结构应力特性分析及强度校核,并基于分析结果采用NSGA-Ⅱ法开展多目标优化分析。结果表明,复合材料外筒强度满足规范要求,且筒体及加强筋所承受的应力最大;相比于优化前的结果,优化后的复合材料外筒质量降低了16.78%,最大应力降低了21.85%,显著减轻了外筒的质量、提高了外筒的强度,为风力助推转子外筒的设计提供了指导性建议。
As an active energy-saving equipment for ships,the weight and strength of the outer cylinder of the wind boost rotor are directly related to the energy-saving benefits and safety performance of the wind boost rotor system.Therefore,this paper carries out the structural stress characteristic analysis and strength checking for the composite outer barrel structure of the wind boost rotor,and carries out the multi-objective optimization analysis based on the analysis results,and the results show that:the strength of the composite outer barrel meets the specification requirements,and the barrel and the reinforcement bars are subjected to the maximum stress;compared with the results before the optimization,the quality of the optimized composite outer barrel reduces by 12.33%,and the maximum stress reduces by 21.85%,which significantly reduces the quality of the outer barrel,and reduces the weight of the outer barrel.Compared with the results before optimization,the mass of the optimized composite outer cylinder is reduced by 16.78%,and the maximum stress is reduced by 21.85%,which significantly reduces the mass and improves the strength of the outer cylinder,and provides guiding suggestions for the design of the outer cylinder of the wind-powered booster rotor.
