Analysis and Research of Moving Simulation Improvement Algorithms Based on Two-body Floating System

The effective utilization of wave energy is one of the important means to solve the shortage ofresources. The dual hydraulic PTO floating system (floating system hereinafter), is an important device for converting wave energy. The system is mainly composed of an energy extraction system (PTO system), float, and vibrator. Under the action of wave energy, the floater and vibrator of the floating body system move relatively, which drives the PTO system to generate electricity. Many researchers have studied the motion characteristics ofa floating body system in a heave state and calculated the energy conversion characteristics accordingly. In practice, the floating body system heaves and pitches due to wave energy. We propose an improved motion simulation algorithm for the Double Floating Body System based on the original researchers. The improved motion simulation algorithm adds the floating body’s pitch motion state, considers the floating body’s motion under both heave and pitch, and further analyzes the power conversion characteristics based on the motion characteristics.
