摘要

对实测采样振动信号的滤波处理,验证了形态滤波器在抑制信号干扰、保留信号原有特征方面的作用。定量分析了形态滤波器设计中结构元素的形状、宽度、幅值等因素对形态滤波器性能的影响程度以及振动信号的采样频率对结构元素尺寸的影响,并根据数据分析结果得出了在对旋转机械振动信号进行降噪滤波处理时,形态滤波器中结构元素的形状及尺寸的一般设计规律。

Abstract

Sampling real vibration signal with interferences was processed by morphological filtering, and the effect of noise reduction and primal feature reservation of morphological filtering is validated. The influences of the shape, width and amplitude of the structure element on the performance of morphological filters, and the influences of the vibration signals sampling rate on the size of structure element have been analyzed. Based on the analysis results, the general rule for shape, size of structure element on the design of morphological filter is elicited, which can be applied for de-noising and filtering of rotating machinery vibration signals.
