为研究船首开槽布置偏离船中纵剖面程度对超大型自航绞吸挖泥船操纵性造成的影响，本文以某超大型自航绞吸挖泥船为研究对象，采用RANS方程和VOF算法，对其进行约束模型试验模拟。结果表明开槽布置影响原有流场对称性，导致船体所受横向力和艏摇力矩增强。在静水条件下，该船模水动力导数随开槽位置变化表现出较明显的规律性与相关性，水动力导数$ Y_{\dot{v}}^{'}、Y_{v}^{'} $、$ N_{\dot{v}}^{'} $和$ {Y}^{'}_{\dot{r}} $与偏置程度呈正相关，$ Y_{vvv}^{'} $、$ Y_{rrr}^{'} $、$ N_{\dot{r}}^{'} $与偏置程度呈负相关。直线稳定性衡准数随开槽偏置程度增加呈下降趋势。
In order to study the influence of the deviation of the bow slot arrangement from the longitudinal section of the ship on the maneuverability of a super-large self-propelled cutter suction dredger, This paper takes a super-large self-propelled cutter suction dredger as the research object, and uses the RANS equation and VOF algorithm to simulate the constrained model test. The results show that the slot arrangement affects the symmetry of the original flow field, resulting in an increase in the lateral force and bow rolling moment on the hull. The hydrodynamic derivatives in calm water show obvious regularity and correlation with the change of slot position. Hydrodynamic derivatives $ Y_{v}^{'} $、$ N_{v}^{'} $、$ N_{r}^{'} $ are positively correlated with the degree of deviation, while $ Y_{vvv}^{'}、Y_{rrr}^{'}、N_{\dot{r}}^{'} $ are negatively correlated with the degree of deviation The stability criterion shows a downward trend with the increase of the deviation of the slot.
