Research on risk of extrusion and collision based on ship hull collision simulation model

In order to analyze the real-time risk of the confrontation between a law enforcement boat and a suspected vessel, the method of simulation confrontation on simulator was used to carry out experimental research. 3122 sampling points in the experiment was collected to observe the changes of rudder angle, heading and ship speed when two ships confronted each other. The simulation model of ship hull collision is established on the ship incurring extrusion, and the risk of extrusion of ship hull structure is analyzed by numerical analysis, which provides theoretical support for commanders to evaluate the risk of collision damage and command decision-making.
