“…is is an encouraging result. In the brake squeal research community, it is well known that brake squeal can be suppressed or eliminated by modifying the structure of the brake system, and some practical applications proved to be successful in the suppression and elimination of brake squeal [28,29]. In the present study, the structure modification method was used to improve the resistance of the wheelset-track systems to rail corrugation.…”

“…Nowadays, there are three kinds of metro wheel structures used in China. Among these three kinds of metro wheel structures, the majority is characterized by an S-shape web plate as shown in Figure 2(a), and the minority is characterized by plane web plates as shown in Figures 2(b [28] and Zarraga et al [29] revealed that the different structures of friction systems could suppress or remove frictional self-excited oscillation of the friction system in some cases. e authors made many heuristic simulation calculations and have found a heuristic wheelset structure, which can remove frictional self-excited oscillation of the wheelset-track system, then rail corrugation.…”

Rail corrugation on low rails of sharp railway curves is still a difficult problem to solve worldwide. Nearly all low rails of the sharp railway curves incur rail corrugation. In the present study, an active method to remedy rail corrugation was studied. From the viewpoint of the frictional self-excited oscillation of a wheelset-track system causing rail corrugation, the effect of wheelset structures on rail corrugation was studied. Three frictional self-excited oscillation models of wheelset-track systems with different wheelset structures were established, which include a heuristic wheelset structure and two being used in the railway industry. The incidence trends of the self-excited oscillations of these three wheelset-track systems were studied. It was found that the wheelset structure has an important effect on rail corrugation, and that the heuristic wheelset structure can restrain or get rid of rail corrugation. With the parameter sensitivity analysis, it was found that when the friction coefficient between the wheel and rail, rail gauge, rail cant, and sleeper span changes to some extent, the heuristic wheelset structure is robust enough to prevent rail corrugation. The proposed heuristic wheelset structure can be used as a potential solution to rail corrugation on sharply curved tracks.

“…The curve squeal that occurs at the inner rail has been extensively and systematically studied. Similar tonal squeal noise, such as the brake squeal noise [17][18][19][20][21][22], is also largely attributed to the above two mechanisms. On the contrary, the flange squeal that takes place at the outer rail is seldom investigated, yet it is also a nonnegligible annoyance in the railway industry [23].…”

“…A brake-clutch in a Spanish company emitted loud squeal noise. The mass and stiffness modifications required to suppress it were determined and the latter was implemented on a laboratory brake-clutch which no longer squealed after a spring was connected to the stationary disc of a simplified brake-clutch system [39].…”

The first International Symposium on Dynamics, Monitoring and Diagnostics was held in Chongqing, China, in April 2022. The Symposium, which was attended both virtually and in person, had an audience of 2000 and was aimed at enhancing the intelligence of condition monitoring for engineering systems. During the Symposium, five keynote addresses were delivered by world leading experts, and this paper is comprised of summaries of these addresses to ensure that the important messages of these speakers are properly on record and readily able to be referenced.
