“…Ma et al [23] proposed a multi-objective optimization method to analyze the vibration attenuation effects of the squeeze film damper parameters on the dynamic response of the system. It was found that in the misalignmentrubbing coupling fault, the amplitude of the fundamental frequency reduced by 7.4%, the amplitude of 2× the fundamental frequency dropped by 51.5%, and the amplitude of 3× the fundamental frequency reduced by 16.8%. Their study provided a theoretical reference for vibration control and the optimal design of rotating machinery.…”

“…Researchers have strived to understand the rub-impact fault, for example, exploring the fault mechanism [8][9][10], the fault feature extraction method [11][12][13], source localization [14,15], and intelligent fault diagnosis [16,17], etc. These studies contributed to the development of rub-impact fault diagnosis and to practical applications.…”

“…19 Studies have also been carried out to see the vibration response under single-point rubbing 20 and multiple-point rubbing. 21 Wu et al 22 applied the one-dimensional (1D) convolutional neural network (CNN) for finding rub defect of turbine rotor. From the study, it has been found that rotor rubbing excites harmonics of rotor speed and natural frequency.…”
