Abstract

In order to ensure the normal operation of the ship propulsion system and ship navigation, this paper analyzes the deformation of a bulk carrier with workbench by means of finite element analysis. The relative displacement of the bearings under different working conditions is calculated, and the relationship between the natural frequency of the ship's deformation and the lateral vibration is obtained by the modal analysis. The results show that the natural frequency of transverse vibration of the same inner diameter shaft is increased gradually in the condition of the ship's sitting, floating and full load. Under the same working condition, the natural frequency of the transverse vibration natural frequency of the shaft is gradually reduced. Therefore, in the same or different working conditions, the ship hull deformation has a great influence on the natural frequency of the different diameter and the same inner diameter of the shaft system.
