动态负载条件下伺服电机轴承故障检测的速度特征分析

As a noninvasive detection method, speed signature analysis for servo motor bearing fault detection has attracted much attention in recent years. The selection of the optimal demodulation band is critical for accurate bearing fault detection. However, under dynamic load conditions, an incorrect band is often selected, resulting in failure of feature extraction. This article proposes an optimal dem...
