An analysis method is proposed for the anchor-pulling test simulation. Taken a ro-ro passenger ship as the research object, based on the variable mass kinematics theory, a real-time and effective dynamic anchor system simulation method is developed and created with SolidWorks and Vortex software, and is compared with the field anchor-pulling scene to verify its feasibility and reliability, which provides effective reference for the anchor system simulation and provides conditions for replacing the wood model test.
