Study on Fluid Characteristic of New Composite Stern Bearing
In order to solve the problem of wear and scorch caused by the stern bearing in the start-stop phase， a new type of bearing with a combination of spiral cavity and ladder cavity is proposed based on the finite element analysis software Fluent. Firstly， the flow field analysis is used to simulate the...

| description | In order to solve the problem of wear and scorch caused by the stern bearing in the start-stop phase， a new type of bearing with a combination of spiral cavity and ladder cavity is proposed based on the finite element analysis software Fluent. Firstly， the flow field analysis is used to simulate the pressure of the traditional bearing and composite bearing. Secondly， the water film pressure is integrated to obtain the bearing capacity， and the influence of the rotating speed on the two is analyzed. Finally， the composite bearing based on fluid-solid coupling is analyzed by using ANSYS Workbench. The results show that the composite bearing has a 20%~30% increase in bearing capacity compared with the conventional bearing， and the deformation is mainly concentrated at the end of the liner， which provides effective theoretical guidance for the engineering practice and has a good engineering prospect. |
