| 摘 要： | 针对船舶耐波性试验采集数据量大,实时处理难的问题,基于Matlab平台,以低通滤波及empirical mode decomposition(EMD)为程序内核,以FFT-FS频谱细化技术为辅助分析工具,开发船舶性能试验数据处理系统,该系统能有效消除测量数据中的噪声,自动识别趋势项,高精度提取频域细化谱,并可执行海量数据的统计分析,以全面获取实测信号的时域及频域特征。

| Abstract: | Aiming at the problems of that the signals measured in the sea-keeping test are usually massive , making it diffi-cult to analysis in real time , a signal deposing system for the sea-keeping test was developed based on the Matlab .The low-pass signal filtering method , the empirical mode decomposition method and the FFT-FS method were applied to depose the signals . This system can remove noises and low-frequency trends in the signals automatically , obtain high accuracy frequency-amplitude information of the signals , and depose massive signals effectively . |
