- 摘要:
- 液体火箭发动机试验启动段的振动信号中包含有大量的噪声分量，通过小波变换的Mallat算法对振动信号进行去噪处理，并通过试车数据对采用的方法进行验证，取得了良好效果，显示了小波去噪在振动信号去噪领域的广泛应用前景。
- Abstract:
- There are strong noise components in the vibration signal generated in ignition shock section during liquid rocket engine test. A Mallat algorithm based on wavelet transform is proposed in this paper for denoising of vibration signal. This denoising method was verified with the actual testing data. The obtained result is
