Pose Prediction Method of Ship Simulation Motion Platform with Stewart Mechanism
To verify the effect of wave on the ship, Stewart platform is designed to simulate ship motion, and NARX (Nonlinear Autoregressive with external input) is used to predict ship motion. Firstly, the 3-level wave spectrum is obtained by analyzing the wave mechanism, and then the Stewart mechanism is designed to solve the simulated ship motion range by forward and inverse kinematics and workspace analysis. Then 6 aspects of ship motion are simulated by numerical simulation. Finally, NARX is used to predict the next moving point of the ship's movement, and the rationality and accuracy of NARX are verified in the Stewart mechanism.
