【摘要】：采用流固耦合(Fluid-Structure Interaction,FSI)的艇體波浪載荷和結(jié)構(gòu)響應(yīng)的數(shù)值分析方法,對(duì)頂浪、斜浪中復(fù)合材料雙體艇結(jié)構(gòu)的動(dòng)態(tài)響應(yīng)進(jìn)行研究。分別建立了完整的復(fù)合材料艇體有限元模型以及流場(chǎng)模型,基于數(shù)值水池造波技術(shù),通過計(jì)算獲得了頂浪、斜浪中復(fù)合材料艇體結(jié)構(gòu)的時(shí)域動(dòng)態(tài)響應(yīng)結(jié)果,選取高應(yīng)力梯度區(qū)域,通過網(wǎng)格加密重構(gòu)同時(shí)獲得了復(fù)合材料的層間應(yīng)力。選取具有代表性的前10大等效應(yīng)力與內(nèi)外面板最值主應(yīng)力,在將FSI與傳統(tǒng)基于經(jīng)驗(yàn)公式的有限元法(Finite Element Method,FEM)的結(jié)果對(duì)比中發(fā)現(xiàn),FSI中拱、中垂的計(jì)算結(jié)果更接近于FEM彎扭組合工況,而采用《鋼制雙體船直接計(jì)算指南》計(jì)算復(fù)合材料雙體艇時(shí),所用經(jīng)驗(yàn)公式的頂浪航行波浪載荷計(jì)算值偏小。
[Abstract]:The dynamic responses of composite catamaran structures in top waves and oblique waves are studied by using the numerical analysis method of the wave loads and structural responses of the ship body of Fluid-Structure interaction FSI (Fluid-Structure interaction FSI). The complete finite element model and flow field model of composite ship body are established respectively. Based on the numerical wave making technique, the dynamic response of composite hull structure in top wave and oblique wave in time domain is obtained by calculation. The interlaminar stress of the composite was obtained by mesh encryption and reconstruction in the high stress gradient region. The top 10 equivalent stresses and the most valuable principal stresses of the inner and outer panels are selected. By comparing the results of FSI with those of the traditional finite element Element method based on empirical formula, it is found that the mid-arch of FSI is more similar to that of FEM bending and torsion combination. However, in the calculation of composite catamaran by means of the Guide to Direct calculation of Steel Catamaran, the calculation value of the wave load of the top wave navigation by the empirical formula is smaller than that used in the calculation of the composite catamaran.
