摘　　要： 在振动测量中,采用基于高斯模型的信号处理方法进行噪声处理,但对于强冲击噪声则出现性能退化。研究α稳定分布信号的特性,提出采用中值滤波结合工程算法的方法进行滤波处理。仿真结果表明,在不同冲击性α稳定分布噪声环境下,采用高斯模型分析结果出现退化,而采用中值滤波变换结合工程算法,对幅值大的尖脉冲噪声具有较强的韧性,变换得到频域信号结果能够表征频率特性,具有更广泛的意义。 In the engineer of vibration measure, for studying the signal characteristic of frequency range, the classic signal processing method was used to analyze the gauss noise accurately, but the stability of performance was degradation in the Alpha stable distribution noise. So the new signal processing method based on the filter and algorithm was explored. The results showed that the new method had better applicability than the classic signal processing method and had the good performance and reliability of the different α-stable distribution noise.
