【摘要】:以船舶操縱水動(dòng)力預(yù)報(bào)為研究背景,利用商用軟件Fine/Marine對(duì)DTMB5415進(jìn)行了低頻純橫蕩及純首搖運(yùn)動(dòng)數(shù)值仿真研究。以純橫蕩運(yùn)動(dòng)幅值為0.064 m試驗(yàn)數(shù)據(jù)為基準(zhǔn),通過(guò)對(duì)比不同邊界條件設(shè)置及其對(duì)計(jì)算結(jié)果的影響分析,得到隨體坐標(biāo)系下船模受到的側(cè)向力及轉(zhuǎn)首力矩,并將仿真計(jì)算結(jié)果與船模試驗(yàn)結(jié)果進(jìn)行對(duì)比,獲得較好的參數(shù)設(shè)置。以該設(shè)置參數(shù)及邊界條件為依據(jù)進(jìn)行后續(xù)的純橫蕩運(yùn)動(dòng)及純首搖運(yùn)動(dòng)數(shù)值仿真計(jì)算,得到船模所受側(cè)向力及轉(zhuǎn)首力矩。
[Abstract]:Based on the prediction of ship maneuvering hydrodynamics, the numerical simulation of low frequency pure roll and pure first roll motion of DTMB5415 was carried out by using commercial software Fine/Marine. Based on the test data of pure swinging motion of 0.064 m, by comparing the different boundary conditions and their effects on the calculation results, the lateral force and the turning moment of the ship model in the coordinate system are obtained. The simulation results are compared with the results of ship model test, and better parameter setting is obtained. According to the setting parameters and boundary conditions, the numerical simulation of pure swinging motion and pure first roll motion is carried out, and the lateral force and turning moment of the ship model are obtained.
