Modeling for ship heave and pitch motions in waves based on conformal mapping method

To develop maritime simulator, mathematical model for ship heave and pitch motions has been established based on conformal mapping method. To verify the validity of the mathematical model, the numerical simulation research is carried out with Wigley model M in regular waves with diiferent Froude number. Comparisons between the simulation results and the experimental data manifest that the proposed mathematical model is correct and reliable. Then the mathematical model accesses maritime simulator's visual simulation system achieving a favorable effect.
