DESIGN METHOD OF SHIP ICE BREAKING RESISTANCE MODEL TEST BASED ON NON-FREEZING MODEL ICE

摘要

The present invention relates to a design method of a ship ice breaking resistance model test based on non-freezing model ice. The method comprises the following steps of: determining the total length L₁, molded breadth B, and scale ratio λ of a selected ship model; determining the size A₁ of an experimental basin for placing broken ice in the ship ice breaking resistance model test; determining the characteristic length of model ice; determining the amount proportion of the model ice of each size under a target coverage rate c of the model ice; obtaining the amount of the model ice of each size under the target coverage rate c of the model ice according to the amount proportion of the model ice of each size under the target coverage rate c of the model ice and the total area A₂ of the model ice; and determining the geometric shape and parameters of the model ice of each size under the target coverage rate c of the model ice. The present invention solves the problems of poor economy and poor operability in a freezing model ice experiment of an ice water tank, and provides a design method for carrying out a ship ice breaking resistance model experiment in a towing water tank.
