Co-Simulation of Multibody System Dynamics and Moving Particle Semi-Implicit Method for Heavy Load Lifting Operations in Shipyards Available to Purchase

Since various existing simulation tools based on multibody system dynamics (MSD) focus on conventional mechanical systems, such as machinery, car, and spacecraft, there are some problems with the application of such simulation tools to shipbuilding domains due to the absence of specific items in the field of naval architecture and ocean engineering, such as hydrostatics and hydrodynamics. Thus, in this paper, we describe how to simulate heavy load lifting operations in shipyards by using multibody system dynamics and moving particle semi-implicit (MPS) method. The crane systems in shipyards are all multibody systems which the multiple rigid bodies are jointed together, so the multibody system dynamic was used to analyze its dynamic response. The moving particle semi-implicit method was applied to compute nonlinear motions of a floating vessel. Co-simulation with these two method was applied to actual operations in shipyards.
