Mathematical Model for Surface Ship Maneuvering.

摘要

The mathematical model for a time domain simulation of a surface ship maneuvering in calm water is presented. The six degree of freedom mathematical model is applicable to conventional monohulls or SWATHs. Included are calm water hydrodynamic forces, hydrostatic forces, unsteady wind forces, slowly-varying wave drift forces, and forces due to a towed body. The model depends upon data derived from model experiments. This model represents an improvement over previous models in several respects. Most notable are the changes in the modeling of resistance, calm water surge hydrodynamic forces, and propeller-rudder interaction which together lead to improved speed loss prediction.
