摘要
采用小波多分辨分析方法对钎杆应力波进行分解 ,得到各频率段应力对钎杆负载的贡献 ,识别的信息将有利于钎杆疲劳和凿岩系统破岩机理的进一步分析 ,同时对凿岩规范和钎钢开发有指导作用。
The wavelet transformation is applied to decomposed the drilling string stress wave into vavious frequency channels wavelet components,and the dffects of the different wave components to drilling string and the rock crack is reviewed in this paper.
