【摘要】：為了分析具有特殊船型的近海風電設(shè)備安裝船的底部砰擊問題,論文提出了一種適用于風電設(shè)備安裝船的底部砰擊載荷計算流程。其中,基于波浪勢流理論計算有航速船舶在波浪中的運動響應,利用多項式擬合典型剖面在入水前后時刻的垂向速度時間歷程曲線,基于計算流體力學理論數(shù)值模擬二維船型剖面入水砰擊載荷。然后,針對計算流程中的關(guān)鍵環(huán)節(jié)進行實驗數(shù)據(jù)對比分析,驗證了船舶運動響應和二維剖面入水算法的準確性。最后,根據(jù)論文計算方法對近海風電設(shè)備安裝船的底部砰擊特性進行研究。
[Abstract]:In order to analyze the bottom slamming problem of offshore wind power equipment installation ship with special ship type, this paper presents a flow chart for calculating the bottom slamming load of wind power equipment installation ship. Based on the theory of wave potential current, the motion response of ships with speed in waves is calculated, and the time history curve of vertical velocity of a typical section before and after entering water is fitted by polynomial. Based on the theory of computational fluid dynamics (CFD), the water slamming load of two-dimensional ship profile is numerically simulated. Then, the accuracy of ship motion response and two-dimensional section water injection algorithm is verified by comparing and analyzing the experimental data of the key links in the calculation process. Finally, the bottom slamming characteristics of offshore wind power installation ship are studied according to the calculation method.
