Abstract


One example of marine simulator as the simulation technology has been widely used in the nautical field , made ??a great contribution to the maritime education and training , port waterway engineering safety demonstration . Need to have a certain type of ship in order to enrich the marine simulator as well as a reserve , and the SWATH catamaran model is applied to the marine simulator . Completed the first step in this task , and SWATH catamaran movement is to establish mathematical model . Due to limited time , only three degrees of freedom motion of the SWATH catamaran modeling and simulation . Access to a large amount of information about the SWATH catamaran and related aspects of research and summarize these data . First the small waterplane catamaran status quo as well as the advantages and disadvantages of starting , and then the overall evaluation of the performance of SWATH catamaran determine the ideological the MMG separation modeling for modeling and simulation . In the modeling process , SWATH catamaran bare hull , propeller and rudder at fluid hydrodynamic paddle at the wake coefficient , thrust deduction coefficient , and the hull and paddle , rudder between mutual interference of water the power to carry out a detailed analysis and calculation . Last in VC 6.0 platform using a fourth-order Runge - Kutta methods integral SWATH catamaran state of motion . Created to validate the correctness and feasibility of the model , Japan 's second ship SWATH catamaran \face catamaran manipulate the laws of motion , the motion mathematical model is correct and effective . The mathematical model established in this paper provides a theoretical basis for the research and development of mathematical models of the medium and small waterplane marine simulator catamaran movement .
