| 摘 要： | 在工程实测信号中,振动加速度信号含有直流分量和干扰噪声,这些信号成分在积分后导致误差的累积,可能使得到的结果完全失真。在分析趋势项对软件积分的影响的基础上,提出了基于频域低通和带通滤波的频域积分算法。实例验证这种方法可以很好地去除低频趋势项和高频干扰噪声。

| Abstract: | In engineering measurement signals,the vibration acceleration signal contains direct component and interference noise.These signal components lead to the accumulation of error after the integral,which may make a complete distortion of the results.On the analysis of the influence the trend term having on software integral,the frequency domain integral algorithm based on the frequency domain low-pass and band-pass filter was put forward.Through validation examples,this method is very well used to remove the low frequency trend term and the high frequency interference noise. |
