摘　　要：冰区加强船舶在冰区航行过程中,由于螺旋桨叶片与碎冰碰撞,导致其螺旋桨除了正常桨叶与水相互作用产生的力矩以外,还存在冰载荷激励,其造成的瞬态冲击会导致船舶柴油机发生转速波动,进而对航行安全造成较大影响。本文通过开展基于调控作用的冰区加强船舶转速稳定性提升方法研究,突破瞬态冲击下基于调控作用的船舶柴油机实时转速仿真计算技术,形成受到冲击负载后的柴油机转速稳定性提升方法。以某型冰区加强船舶柴油机为例,经该方法优化后,其转速稳定性由6.25提升至11.11。There exists an extra force besides the torque generated by the interaction force of the propeller and sea water during the sailing of an ice-strengthened ship,called ice load excitation,due to the collision between the propeller blades and crushed ice,which can create transient impact and change the rotational speed of the diesel engine in the ship,therefore impacts the navigational safety for the ship.The paper conducts research on the method of improving the rotational speed stability of ice-strengthened ships based on regulation,breaks through the real-time rotational speed simulation calculation technology of ship diesel engines based on regulation under transient impacts,and forms a method to improve the rotational speed stability of diesel engines after being subjected to impact loads.The authors applied the proposed method on a specific ship diesel engine,the result implied that the corresponding rational speed stability raised from 6.25 to 11.11.
