摘要
针对船舶做全回转操纵时的瞬态工况问题,以轴系校中、油膜动力学等理论为基础,考虑螺旋桨轴承力、主机激励力和转船离心力等瞬态因素的影响,建立船舶推进轴系运行状态瞬态响应预测模型。以某64000 t散货船为对象,进行瞬态响应计算流程设计与实船仿真计算。计算结果表明:转船离心力对船舶推进轴系运行状态响应变化影响显著,且随着转船离心力增大到某个临界值时或轴承安全间隙值较小时容易造成尾轴承异常磨损。
The effects of the transients of propeller bearing force,main engine excitation force and the centrifugal force are reflected in the model.The 64000 t bulk carrier is calculated for illustration.The calculation shows that the centrifugal force during turning has a significant influence on the response of the ship propulsion shafting and abnormal wear of stern bearing can be easily caused when the centrifugal force increases to a critical value or when the safety clearance value of the bearing is too small.
