MATHEMATICAL MODELING OF CONDITIONS OF INITIATION AND DEVELOPMENT OF EXTREME BROACHING SITUATION ON IRREGULAR WAVES

摘要

A mathematical model of "broaching" dynamics on irregular waves has been formulated. The conditions of initiation and development of this extreme situation for various characters of waves are considered. The mathematical modeling of interaction process of a ship with external environment in conditions of "capture" and turn of a ship on irregular following waves has been made. The new experimental facts and laws allowing to carry out interpretation of the given dynamic measurements at the control and the forecast an extreme broaching situation in onboard systems of a navigation safety are established. The report is accompanied by demonstration of physical pictures and features of ship behavior in a mode of uncontrollable changes of a ship on following irregular waves.
