摘要

与金属相比,纤维增强复合材料具有高强度、高刚度、重量轻、优越的阻尼性能和出色的设计能力等优点。通过使用合适的材料和排列铺层顺序,可以调整复合材料层合板在不同方向上的刚度特性,以满足应用的要求。因此,本研究的目的是从水动力和结构性能两方面探讨铺层型式对螺旋桨性能的影响。提出了一种基于有限元法(FEM)和计算流体力学(CFD)相结合的瞬态流固耦合(FSI)算法,并将其应用于复合材料螺旋桨的分析。将螺旋桨的水动力性能与金属材料进行了比较。比较了三种不同工况下不同铺层方案的螺旋桨推进效率、结构变形、等效应力和损伤性能。此外,还提出了一种参数优化方法,以获得具有最佳水动力性能和结构性能的复合材料叶片最合适的铺层方案。

Hydrodynamic performance optimization of marine propellers based on fluid-structure coupling
Fiber-reinforced composites offer the benefits of high strength, high stiffness, lightweight, superior damping performance, and great design capability when compared to metal. The rigidity characteristics of the composite laminate in different directions may be adjusted to meet the requirements of the application by using appropriate materials and arranging the lay-up sequence. As a result, the purpose of this work is to explore the influence of lay-up type on propeller performance in terms of both hydrodynamic and structural performance. A transient fluid-structure interaction (FSI) algorithm based on the finite element method (FEM) combined with the computational fluid dynamics (CFD) technique is developed and used for the analysis of composite propellers. The hydrodynamic performance of the propeller is compared to that of a metallic material. Propeller propulsion efficiency, structural deformation, equivalent stress, and damage performance of different lay-up options under three different operating situations are compared. In addition, it is presented a parametric optimization approach to get the most appropriate lay-up program for composite blades with the best hydrodynamic properties and structural performance.
