Vessel maneuverable characteristics as functions of its mathematical model parameters

The concept of parameters of a ship mathematical model influencing on her maneuverable characteristics has been introduced. As an example some factors of influence for a number of maneuverable characteristics have been calculated: a radius of the established circulation of a vessel, a ledge in the evolutionary period of circulation, an initial vessel turning and all characteristics of gaining.

On comparison of mathematical models from the point of view of influence factors

Using of influence factors of the mathematical model parameters of a ship on her maneuverable characteristics has been shown. The comparison of widespread mathematical models of a vessel has been made with the help of these factors. The influence factors have been applied for changing the model parameters in order to find their optimal conformity to natural tests.
