摘要

探讨了以小波变换为基础的滤波技术在冲击试验后信号波形提取中的应用。针对高电压冲击和大电流冲击信号的处理问题

采用不同层次的小波分析方法

将噪声信号从冲击电压和电流信号中提取出来

小波变换的引入使得波形处理更加简单。结果表明

对不同类型的样品进行冲击试验

小波变换都有较好的滤波效果

并很好地保存了信号的边缘特征。波形的处理结果也表明了该方法的可行性和适用性。

Abstract

The application of filter technique in impulse wave evaluation

based on wavelet transformation

is discussed.In order to deal with signals of high voltage and current impulses

wavelet transformation in different gradations is adopted.By using the method

noise signals are drawn out from impulse signals

and it is more convenient for handling the waveform.Results show that wavelet transformation has a better filter effect for the impulse signal

and the edge characteristic of the signal has been well kept.Results of the waveform also show the feasibility and suitability of presented method.
