摘要
介绍小波变换的原理及其特点 ,列举其在轨道检测中的典型应用 ,并仿真分析垫层、道床刚度的变化对客车轴箱加速度的影响 ;同时 ,对如何选用小波函数和与其他技术相结合进行信号分析作了说明。
The paper introduces the principle and features of wavelet variation,and gives an example of its typical use in track detection.A simulation analysis was made of the influence of base course and track bed stiffness variation on acceleration of axle box of cars.The paper also illustrates how to adopt wavelet function and how to combine it with other technology to analyze signals.
