Finite element analysis of dead force and fatigue of chamber gate of large ship - lift

This paper analyzes dead force and fatigue in chamber gate of ship - lift based on structure strength and fatigue design theories, and finite element method. First it determines some parameters for calculation according to fatigue design theory, then analyzes different conditions, finally builds finite element model of arc chamber gate and carries out the numerical simulation analysis under different conditions with the structure analysis software ANSYS. The results show that the gate is able to meet fatigue and strength requirement during the whole service life.
