Abstract

According to the design complexity due to the diversification of ship motion simulator structure and control system, we put forward that combining Stewart parallel structure based on modular design with open control system based on EMC2 controller. The system utilizes PC based on the hardware structure such as motion control interface card, servo electric cylinder and software structure such as real-time operation system UBUNTU and professional control software EMC2 which can ensure the system’s being real-time. We have studied the movement law of ship in waves and obtained the ship movement sample changing with time in waves. And we do the ship motion simulation well with the motion simulator system.
