| 摘 要： | 针对小波类去噪方法存在基函数的选择,同时未摆脱Fourier变换为基础带来的缺陷、EMD去噪存在模式混叠的问题,将EEMD去噪引入到爆破振动信号处理领域.首先利用仿真试验验证了EEMD克服了EMD的固有缺陷,然后分别利用小波、EMD、EEMD对数值微分所获取的加速度时程曲线进行低通去噪处理,对比结果表明:EEMD不仅具...

| Abstract: | Aim at the problem of function choosing,Fourier based transform and EMD denoising method existing in the wavelet de-noising method,the EEMD decomposition de-noising was introduced to blasting vibration signal processing field.Firstly,the simulation experiment was used to verify EEMD overcoming the faults of EMD.Secondly,the wavelet decomposition,EMD and EEMD were used respectively to low-pass denoising dispose the acceleration time-histories obtained by numerical differentiation.The comparison results show ... |
