Sea state simulation: The platform can realize six directions of rolling, pitching, sag, roll, pitch and yaw, and the six directions of the movement can be combined and superimposed to combine a variety of working conditions, including the movement platform, electric cylinder, computer control system, hardware, system control software, drive system, electric control system, etc., to meet the technical requirements of dynamic simulation of sea environment equipment, and can simulate 0-5 sea conditions. The corresponding waveform diagram is drawn.
