Mathematical Models in Design Process of Ship Bow Thrusters

The paper describes an application of simulation models for computer-aided design of ship bow thrusters. Generation of simulation models of ship bow thruster requires development and verifying of mathematical models of system component elements. Using the results of simulation the expert system is able to determine, that the rules of classification societies are met. Design procedures and mathematical models are part of an expert system for computer aided design of ship power systems. As an example, the simulations investigation of the bow thrusters dynamics are presented. As a result of the research simulations, the plots of electrical supply, load current, load torque, and rotation speed of the induction motor are presented.
