Kalinichenko Y. Perfection of algorithms of the informative providing of manoeuvring of vessels

Theoretical bases of maneuvering of ship are considered in work, mathematical models taking into account the dynamics of ship at the change of his course and speed are got. The features of agility of ship are described by five models of his rotatory motion. Experimental information of rotatory motion of ship is got, and it is shown that with exactness acceptable to the practical needs motion of ship at a turn can be described by the third dynamic model. Correct expressions characterizing motion of ship at the active and passive braking are got. The task of stop of ship in the set point at the active and passive braking taking into account the flow in the district of maneuvering is considered. Analytical expressions for the calculation of parameters of maneuvers are represented in a kind comfortable for application of numeral methods of calculation. Programmatic realization of six most essential tasks of maneuvering of ship taking into account descriptions of agility and inertia-brake descriptions which can be used in the ship computer system of providing of maneuvering of ship is considered. In conclusion of work the methods of determination of parameters of maneuver of ship from the experimental information got in the model supervisions are resulted.. With the got parameters showed the design of turn of ship good of results of design with experimental material. The alternative method of calculation of parameters of the active and passive braking of vessel is considered: distance and time of sailing of ship. By the offered alternative method the calculation of parameters of braking of the motor ship "Uelen" is produced, the values of which practically coincide with the values got at the mooring tests. The calculation of inertia-brake descriptions of m/v "ELQUI" for the loaded state and in a ballast is executed. Dependences of size and time of sailing of ship at the active braking from speed of ship before braking are represented in a tabular kind. Besides tabular dependences graphic curves representing dependence of parameters on speed of ship are resulted, got by the computer program.
