Abstract
This article studies finite element simulation technology,focuses on analyzing finite element calculation the-ory,and elaborates on the material model theory of ship bearings.At the same time,the stress-strain curve of the constitutive model of ship bearings is provided;A dynamic simulation analysis was conducted on ship bearings,and a suction device was used instead of a propeller during the simulation process.A calculation method for propeller torque excitation was provided,and the angular acceleration,angular velocity,and radial force of ship bearings were analyzed;Finally,finite element simula-tion was conducted on the bearing capacity of ship bearings,and simulation analysis was conducted on the amplitude,fre-quency,and force situation of ship bearings.
