摘要
为实现实船抗冲击实验中船体结构冲击响应信号的快速、准确处理,分析了冲击响应信号的特点以及信号的预处理、时域处理和频域处理的方法,提出了一种全新的基于SIMULINK的模块化信号处理概念,通过SIMULINK建模的方法实现了信号的漂移修正、数字滤波、积分变换和时频分布计算,并通过可视化模块实现了处理结果的可视化;结果表明:该方法不但省去了烦琐的编程工作,而且处理速度快,可视化效果好,为舰船冲击响应信号处理开辟了一条新途经。
In order to realize the quick, accurate processing of impulse response signal of warships in ship impact resistance test, the characteristics of impulse response signal and the preprocessing, time processing and frequency processing methods are analyzed, and a new concept of modularization signal processing based on Simulink is put forward. Digital filter, integral transformation and time and frequency distribution calculation of signal are achieved through Simulink model building method, as well as the visualization of processing results through the visual module. The results proved that.. The method in this paper has not only saved futile programming work, but also realized a good processing effect and a fast processing speed. It offers a new method for impulse response signal processing of warships.
