| 摘 要： | 对车辆的运动状态和动态轴重信号干扰的产生进行分析，在此基础上对车辆动态轴重信号的噪声在小波变换下的特性进行了说明，据此提出一种可有效消除车辆动态轴重信号噪声的软阈值选取方法；通过具体仿真实例说明该阈值处理方法的优点，表明基于该方法对车辆动态轴重信号消噪是很有效的。

| Abstract: | The moving condition and the generation of spindle's dynamic weight interfering signal of the vehicles are analyzed. On the basis of that it explains the characteristics of the vehicle spindle's dynamic weight signal's noises under wavelet transform, and a method is proposed to eliminate noise with soft threshold. The virtue of the method is showed by the specific simulation example and the method is proved very effectively applied to dismissing the vehicle spindle's dynamic weight signal's noises. |
