Feature Recognition on Friction Induced Vibration of Water-Lubricated Bearing under Low Speed and Heavy Load

Under low speed and heavy load operating conditions, the marine water-lubricated bearing (WLB) is often in a mixed lubrication state. This leads to abnormal friction-induced vibrations and noise in underwater vehicles. An empirical mode decomposition (EMD) based method for identifying friction-induc...
