船舶操纵仿真中图谱数值化方法的研究

Probe into the Method for Figure Transformation of Spectrum of the Graph in Ship Operating Simulation

在船舶操纵仿真中涉及大量的图谱转换工作,传统的图谱处理方法在精度和工作量上存在着一对矛盾。本文试图通过应用正弦小波拟合方法来替代传统折线方法,并在某些图谱上得到验证,可望在类似图谱数值化上得到推广和应用,以提高计算精度和减少计算工作量。

A lot of transformation from spectrum of the graph is involved in ship operating simulation, the traditional methods exist contradiction between accuracy and workload. This paper analyses a new method to substitute way of sinusoidal small waves curve fitting for way of traditional broken line, and it is validated in some spectrum of graph. If this method is applied to the similar figure transformation of spectrum of graph, it is possible to improve the accuracy and lessen the calculating workload .
