The 6DOF ship motion simulator can simulate the ship's attitude in the sea surface such as rocking, rolling and other postures as well as composite postures, and it can import the wave spectrum to restore the ship's real attitude in the sea surface.
The 6DOF ship motion simulator has the following functions
1, position simulation, sine wave simulation, single-degree-of-freedom motion, multi-degree-of-freedom composite motion.
2、Road spectrum filter processing, random wave reproduction, road spectrum, wave spectrum, flight spectrum reproduction and other functions.
3, through the TCP / IP protocol, to provide users with third-party control interface (host computer interface).
4、Provide internal synchronization and external synchronization data output control interface.
During the motion platform action, it needs to read random action files and involves the superposition of multiple actions, which requires that the motion trajectory must be smooth and conductive so as to ensure the smooth operation of the servo motor, so when planning the trajectory, five times non-uniform B-splines are used.
Five times non-uniform B spline is the promotion of Bézier curve, it retains all the advantages of the Bézier curve, and solves the shortcomings of its localization is not easy to modify, the more control points the higher the number of curves and so on, so our company has in the study of the five times non-uniform B spline applied to the six degrees of freedom platform trajectory planning.
