【摘要】：螺旋槳作為船舶的主要推進(jìn)裝置，與其他類(lèi)型推進(jìn)裝置相比，其推進(jìn)效率高。 近年來(lái)，復(fù)合材料螺旋槳研究成為熱點(diǎn)，，受到廣泛關(guān)注。本文主要分析了均勻來(lái)流情況下，復(fù)合材料螺旋槳的水動(dòng)力性能和變形、應(yīng)力分布等性能，結(jié)合計(jì)算流體力學(xué)方法和有限元法，提出了一種計(jì)算復(fù)合材料螺旋槳流固耦合問(wèn)題的數(shù)值方法。 在回顧和總結(jié)國(guó)內(nèi)外關(guān)于復(fù)合材料螺旋槳研究工作的基礎(chǔ)上，本論文采用流固耦合數(shù)值模擬方法，研究復(fù)合材料槳的流固耦合特性。 在第三章中，采用脫體渦模擬（DES）和雷諾平均方法（RANS）模擬螺旋槳水動(dòng)力性能，采用不同網(wǎng)格密度研究了模型的網(wǎng)格依賴性，獲得詳盡水動(dòng)力信息，并對(duì)兩種湍流模型的計(jì)算結(jié)果進(jìn)行比較。結(jié)果表明：在較低進(jìn)速系數(shù)情況下，由于流動(dòng)存在分離，采用DES方法能獲得比RANS方法更為準(zhǔn)確的計(jì)算結(jié)果；而在其他進(jìn)速系數(shù)情況下，DES方法和RANS方法的計(jì)算精度相當(dāng)，但是DES方法可以獲得比RANS方法更為精細(xì)的流動(dòng)信息，更能真實(shí)反應(yīng)流動(dòng)的復(fù)雜特征 在第四章中，將計(jì)算流體力學(xué)方法和有限元方法相結(jié)合，對(duì)VP1304復(fù)合材料螺旋槳非定常流固耦合性能進(jìn)行研究，設(shè)計(jì)三種不同復(fù)合材料鋪層，并分析不同鋪層設(shè)計(jì)對(duì)螺旋槳水動(dòng)力性能、壓力分布、槳葉變形和應(yīng)力分布信息等的影響規(guī)律。結(jié)果表明，復(fù)合材料螺旋槳敞水性能與剛性螺旋槳基本接近，但由于復(fù)合材料密度較金屬材料為小，復(fù)合材料螺旋槳減重明顯�？紤]到大側(cè)斜的螺旋槳槳葉更容易產(chǎn)生大的變形，對(duì)螺旋槳性能影響更明顯。對(duì)72度大側(cè)斜螺旋槳DTNSRDC4383進(jìn)行復(fù)合材料鋪層設(shè)計(jì)，并進(jìn)行流固耦合性能進(jìn)行研究�？紤]正交對(duì)稱鋪層和±45°均衡對(duì)稱兩種鋪層方式，計(jì)算并對(duì)比分析了二者的水動(dòng)力性能、尾流場(chǎng)特性、幾何變形規(guī)律以及應(yīng)力分布特征等問(wèn)題。計(jì)算結(jié)果表明：復(fù)合材料螺旋槳水動(dòng)力性能要優(yōu)于剛性槳，兩種鋪層方式復(fù)合材料螺旋槳性能各有優(yōu)劣。
[Abstract]:As the main propulsion device of ship, propeller is more efficient than other propulsion devices. In recent years, composite propeller research has become a hot spot and received extensive attention. In this paper, the hydrodynamic properties, deformation and stress distribution of composite propeller under uniform flow are analyzed, combined with computational fluid dynamics method and finite element method. A numerical method for calculating the fluid-solid coupling problem of composite propeller is presented. On the basis of reviewing and summarizing the research work of composite propeller at home and abroad, the fluid-solid coupling characteristic of composite propeller is studied by using fluid-solid coupling numerical simulation method in this paper. In chapter 3, the hydrodynamic performance of propeller is simulated by (DES) and (RANS). The grid dependence of the model is studied with different grid density, and the detailed hydrodynamic information is obtained. The calculated results of the two turbulence models are compared. The results show that the DES method can obtain more accurate results than the RANS method because of the separation of the flow under the condition of low precession coefficient. In other cases, the accuracy of DES method and RANS method is the same, but the DES method can obtain more precise flow information than RANS method, and can reflect the complex characteristics of flow more truly in Chapter 4. The unsteady fluid-solid coupling performance of VP1304 composite propeller was studied by combining computational fluid dynamics method with finite element method. Three kinds of composite laminates were designed, and the hydrodynamic properties of propeller with different layering designs were analyzed. The influence of pressure distribution, blade deformation and stress distribution information. The results show that the open water performance of composite propeller is close to that of rigid propeller, but because the density of composite material is smaller than that of metal material, the weight loss of composite propeller is obvious. Considering that the propeller blades with large slanting propeller are easy to produce large deformation, the effect on propeller performance is more obvious. The composite lamination design and fluid-solid coupling performance of 72 degree large side inclined propeller DTNSRDC4383 were studied. Considering the orthogonal symmetrical layering and 鹵45 擄equilibrium symmetry, the hydrodynamic properties, wake field characteristics, geometric deformation and stress distribution characteristics of the two layers are calculated and compared. The results show that the hydrodynamic performance of composite propeller is better than that of rigid propeller.
