摘 要: 根据锚固质量无损检测信号的特点,基于小波变换(wavelet transform,WT)理论,将原始信号分解为不同频带,并滤除不需要的频带,最后用Mallat重构算法得到去噪后的信号,从而有效地提取到所关心频段的检测信号。实际检测信号的处理结果表明:它能较好地去除非关心频段干扰信号,使用该方法处理所得信号的信噪比明显提高,从而为锚固质量检测精度和稳定性的提高打下良好基础。
关 键 词: 固体力学;锚固质量;检测;小波变换

Abstract: In this paper based on characteristic of nondestructive testing signal from rockbolt supporting system, the wavelet transform(WT) was used to divide original signal into different bandwidth and filter the unnecessary bandwidth signals. Meanwhile, the Mallat reconstruction algorithm, which can filter the signal with noise efficiently while holding the characteristics of the original, was brought forward to gain the signal without noise. At last, the transforming result shows that it would make the system run more precisely and stably in the testing to the quality of rockbolt supporting system.
