SpletA 6 DOF (Degree of Freedom) motion platform is a device that simulates motion in 3 axes of rotation (pitch, roll, and yaw) and 3 axis of translation (heave, surge and sway). The platform is engineered to replicate the motions experienced by an object or vehicle in these six directions, creating an immersive simulation experience. SpletOnly vertical ship motion (heave) is available in this Delayed Heave output. Surge and Sway are not provided in this mode of operation. Center of Rotation and Deported Heave Operation When analyzing the heave motion, we can find that part of the heave motion is due to the vessel rotations.
