摘要/Abstract

摘要： 轴系运行环境和工况的多变性、复杂性致使尾轴承负荷存在不确定性。运用随机理论,建立了计入多因素作用的船舶轴承负荷不确定性计算模型,形成了多因素作用下的船舶轴承负荷不确定性计算方法,并通过算例验证了理论模型的正确性。以某大型集装箱船为例研究了船体变形、螺旋桨水动力垂向力、轴承磨损三因素作用下尾轴承负荷的变化规律,对船舶尾轴承计算方法提出了建设性的意见和建议。

关键词: 船舶尾轴承, 负荷不确定性, 表征方法, 随机理论

Abstract: Since the variety and complexity of the stern bearing's operational environment and working conditions, the stern bearing load has uncertainty characters. The mathematical model of uncertainty reaction force of bearing is established including multiple random factors by using the stochastic theory; the uncertainty calculation method is formulated; and the calculation example is put forward to verify the validity of the theoretical model. The influence law among multi factors such as hull deformation, propeller hydrodynamic vertical force and bearing wear is revealed for the uncertainty reaction force of ship stern bearing by taking a large container ship as example. The comments and suggestions for the load test and marine stern bearing research are put forward, which can provide theoretical reference for the engineering practice and the specification.

Key words: ship stern bearing, loading uncertainty, characterization method, random theory
