Application of Improved Chaos Algorithm in the Identification of Rolling Motion of Trimaran
In this paper,a high-speed slender composite trimaran is selected as the research object.Considering the structural characteristics of the trimaran and the flow field around,the design variables,constraints and objective function have been selected to construct five kinds of optimization models.Chaos algorithm combined with parallel and hierarchical strategies has been applied in the design of the identification software system for rolling motion of trimaran.Finally,some rolling motion equations have been obtained by using the identification software with different strategies.Analyzing the results from true experiment and identification software,the best rolling motion equation can be obtained,which has verified the reliability of the identification software.On the other hand,a better algorithm for the identification system has been designed,which provides a basis for the further study on the trimaran.Research shows that the appropriate number of parallel calculation and carrier calculation,the properly selecting the design variables used for parallel calculation and the appropriate carrier probability will help to increase the identification accuracy.
