【Abstract】 This paper presents the principle of high-pass-absolute-value demodulation tcchnigue which is applied with spectrum analysis to investigate the vibration and noise produced by the C61 32 Lathe. The main noise sourse is found out and some reliable data are provided to decrease the noise and vibration and to improve the dynamic performence of the c6132 Lathe.更多还原
