摘要
在刚性罐道动态测试信号分析中,综合运用多种类型小波和运算分析方法并取得较好的效果。应用小波对容器冲击信号进行定位分析,采用Laplace小波相关滤波法求解分析冲击信号的特性参数,通过小波包分解提取倾角信号中代表罐道弯曲和倾斜的缓慢变化分量。
It is efficient to analyze steel guide dynamic testing signals with multi-type wavelets and analysis methods. The container-steel guide impulsion position was analyzed by the wavelet. The impulsion signal mode parameters were analyzed by the correlation filtering method of laplace wavelet. The very low frequency part of obliquity signal indicating the bend and gradient of steel guide was decomposed by the wavelet packet.
