Operating Performance Study of Ships Propulsive Shaft Including Stern Bearings Stiffness
In this paper,making ship propulsion shaft as the research object,We do research on characteristics of water-lubricated stern tube bearings and operating performance of ships propulsion shaft.Using FEM to discuss the impact law of the geometric properties to water-lubricated rubber bearing stiffness.Combining multiple dynamic and FEM theory,we build propulsion shaft rigid-flexible coupling dynamic model and discuss the influence of stern bearings stiffness.Results show that:In a certain scope,water-lubrication stern tube bearings stiffness changes in linear rule to the length-diameter ratio,and nonlinear change to radius ratio.Bearings stiffness has little influence on reaction force,but has much influence on displacement acceleration.
