The method for determination of permissible speeds of ice-going ships based on a new model of dynamic ice destruction
Abstract
The article discusses the main provisions of the methodology for determining permissible speeds of a ship, based on a new model of dynamic ice destruction. Calculated dependences for determining ice load parameters of the new model do not allow us to explicitly identify the values associated with the speed of movement of a ship, with ice thickness and hull shape parameters. In this regard, the inverse problem of determining the permissible ship speed and ice thickness for a given structural strength presents significant mathematical difficulties. The proposed method for solving the inverse problem is based on the use of the approximation apparatus of the experimental planning method to construct regression dependencies for ice load parameters and the mathematical programming apparatus to establish a connection between construction and ice strength.
