摘　　要：为降低船舶推进噪声,提升船舶隐蔽性能,本文针对主要的磁流体推进器拓扑进行了优化设计与对比研究,对这几种磁流体推进器的拓扑结构分别进行参数化建模,建立对应的解析模型。基于解析模型计算每种磁流体推进器的性能参数,全面分析了结构参数和激励特性对于磁流体推进器性能的影响性。并且基于结构参数与激励特性的分析,在一定的约束内完成各类拓扑结构的优化设计。根据每种磁流体推进器性能最优的解重新建立模型,考虑实际应用时的场景,对比分析这些磁流体推进器的性能特点,并指出各类的磁流体推进器类型提升性能的方向。In order to reduce ship propulsion noise and improve ship concealment performance,several magnetic fluid propeller(MFP)topologies are optimized and compared in this paper.Parametric modeling is conducted for these main topological structures,and corresponding analytical models are established.Based on the established analytical models,the performance parameters of different MFPs topologies are calculated.The influence of structure parameters and excitation characteristics on performances of MFPs is comprehensively researched.Based on the analysis,the optimized designs of different structures are completed within certain constraints.Then,based on the optimal designs of different topologies of MFPs,a comparative study is conducted.The performances and characteristics of different MFPs are compared under consideration of the application situations.In the end of this paper,a conclusion is given and the optimization direction is pointed out.
