| Abstract: | Based on explicit finite elements,using LS-DYNA program,simulation of a large-span radial gate in collision with ships is made.The stress-time curve,strain-time curve,collision force-time curve and energy-time curve are obtained.The study results provide a reliable basis for designing and manufacturing this type of gates. |
