The selection of materials for the liner of water lubricated stern bearing for ships is very demanding.It plays a vital role in achieving excellent features such as increased load,reduced drag,low noise,and wear resistance of the bearings.The mechanical research on the characteristics of stern bearing supporting is extremely crucial.For this problem,theoretical analysis and research was conducted on the influence of bearing structure on bearing capacity.A dynamic model of the stern bearing for real ships was constructed.The laws in structural parameters of bushings,lower bearing shells,and rubber were analyzed.The influence of the reserved gap size of the rubber layer on the load deformation relationship was studied.The influence of contact methods on the structural parameters of bushings,lower bearing shells,and rubber was explored.The research shows that as the thickness of the rubber increases,the deformation of the lining layer gradually decreases.The thickness has the greatest impact on deformation,followed by the distance from the top edge,and the distance from the side edge has the smallest impact.The research provides engineering guidance value for the use and design of water lubricated stern bearings.
