摘要:
本文提出一种利用小波分析提取超偏载系数的方法。由于小波分解重构能够提取有效频率成分,对列车运行状态下轮轨力进行分解重构分析,得到超偏载系数。有效的解决了仅靠现有的人工和车辆静态检测难以判断的车辆自身的运行状态的问题。

Abstract: This paper bring a method of picking-up overloaded or unbalanced freight wagon coefficient using wavelet analysis. For the wavelet decomposing and recomposing make it's efficient to pick-up the interesting frequency component, using it to analysis the wheel-track force, then get the overloaded or unbalanced coefficient. It efficiently solved the difficulty of estimating the vehicle running state by manual or static test.
Keywords: Overloaded or unbalanced coefficient; Wavelet translation; Wavelet decomposing and recomposing
