Modeling and simulation of landing craft beaching and retreating motion by marine simulator
This paper proposes a mathematical model for the landing craft beaching and retrating motion applied to sim-ulators.The model establishes a seabed force model based on the theorem of momentum and moment of momentum,and an anchor chain force model based on the catenary theory.Combined with the theory of separate modeling,a six-degree-of-free-dom mathematical model for the landing craft beaching and retrating motion is established.This model takes into account the influence of seabed substrate,initial velocity,and seabed slope angle,enabling more accurate simulation of the landing craft's movement trajectory during beaching and retrating.In addition,the model extends the functionality of nautical simulators in terms of landing craft maneuvering and emergency operations for ships running aground or stranded,providing strong sup-port for research and applications in related fields.
