摘　　要：基于粘性流体理论,利用6自由度MMG模型,结合非对称双体船的水动力性能特点,建立静水中该类船型在水平面上操纵运动的模型。用开源CFD求解器OpenFOAM对该模型在不同舵角下的定常回转运动和高舵角下的Z形运动进行数值模拟。比较了打左舵和右舵时的操纵运动特性,显示非对称侧体对回转运动和Z形运动具有明显的影响,并实现了对该类双体船操纵性能的预报。Based on the theory of viscous fluid,a six-degree of freedom MMG model is used to simulate the maneuvering motion of an asymmetric catamaran in the horizontal plane in still water.Numerical simulation is carried out with OpenFOAM,an open source CFD solver.Steady rotary motions at different rudder angles and zig-zag maneuver motions at high rudder angles are calculated.Maneuvering motions under positive rudder angles and are compared with that under negative rudder angles.It is shown that the side body of an asymmetric catamaran has significant influence on the rotary motion and Z-shape motion,and maneuvering prediction of the asymmetric catamaran is realized.
