This study deals with the design of the Stewart platform for an efficient 6 Degrees of Freedom (DOF) motion of a ship. The general methods of study of the Stewart platform – forward and inverse kinematics – are complex in nature, and are only applicable in limited and specific cases. In order to study the reduction of design time of the Stewart platform, the (please write the full form) DMU module supported by 3D CAD is used. The results show that the DMU module can easily identify the Stewart platform's clash and movements. In addition, it was also possible to calculate motor control data necessary for the prototype manufacturing process. Comparing the Upper plate angle displacement error of the prototype and the DMU results, the error range was found to be 1.5%.
