Abstract : From the standard equations of motion, mathematical models are developed and standardized for simulation in analog or digital computers. A complete study is done of simulation techniques as applied to the mathematical models. A new technique for simulation of very complex systems of equations including nonlinearities is developed. The model can be used in control studies. Digital simulations of the dynamics of the semisubmerged ship and a submarine in six degrees of freedom are done. This latter with all the nonlinearities and cross-coupling terms included. (Author)
