在利用快速傅里叶变换对离散谱进行校正的基础上,提出并证明了稠密谱校正算法。仿真结果表明,该算法具有精度高、计算量小的优点。该算法已成功地应用于内燃机振动信号的分析。为了计算离散频谱,利用快速傅立叶变换对油底壳上传感器采集的信号进行离散频谱计算,并从混合信号中提取信号。
The algorithm of dense spectrum correction has been raised and proved based on the correction of discrete spectrum by fast Fourier transform. The result of simulation shows that such algorithm has advantages of high accuracy and small amount of calculation. The algorithm has been successfully applied to the analysis of vibration signals from internal combustion engine. To calculate discrete spectrum, fast Fourier transform has been used to calculate the discrete spectrum by the signals acquired by the sensors on the oil pan, and the signal has been extracted from the mixed signals.
