碩士 === 國立成功大學 === 系統及船舶機電工程學系碩博士班 === 95 === The main purpose of the present thesis can be described in three parts: (1) to establish the ship steering system in waves by virtual reality technique (2)to extend (1) to simulate the ship towing system (3) to simulate the three dimensional virtual random waves. Based on the nonlinear mathematical model including the seakeeping and maneuvering characteristics of the ship, the present study integrates the six degrees of freedom motion platform to form a real time virtual reality simulation system to simulate the ship motion in random waves. The 4th Runge-Kutta method is adopted to solve the time history of the ship motions in waves to supply the necessary motion data to the simulation system. The control interface of present virtual reality system is based on VB software. The scenery models are contracted in advance by 3D Studio Max software. The Rudder and RPM commands signals are transformed into digital data through the LabVIEW software and A/D card and transmit to the Fortran program for the ship motion calculation. With the output motion data, the virtual reality ship simulator can be operated according to the commands of the operator. The simulation system for ship maneuvering in waves developed here can be extended to meet the IMO requirement and will be helpful to the related navigation training.
