摘要
旋转机构内摩擦的轨迹包含着反映其运行状态的丰富信息 ,但由于各种信号干扰严重 ,使机构内摩擦轨迹非常杂乱 ,难以从中得到有用信息。本文将小波变换的理论用于提纯机构内摩擦轨迹 ,剔除干扰 ,提取故障特征 ,取得了良好的效果。
There are lots of informations in the locus of the internal friction of a rotor that show some operating states of the whirl about mechanism. However, for the serious interferences, it is so confused that useful informations can not be obtained from it. In this paper, the wavelet transform is used to eliminate the interferences. The features of the fault are extracted easily, and satisfactory results are obtained.
