What is it about?
This study investigates the phenomenon of railway curve squeal noise through the application of a finite element analysis (FEA) method. In more simpler terms, the statement implies that a numerical methodology is employed to examine and investigate the occurrence of high-frequency noise, commonly referred to as "squeal," which arises during the traversal of a train around a curved track. The primary objective of this study is to conduct a thorough analysis, with a specific emphasis on examining the contact area between the train wheel and the track when subjected to a predetermined yaw angle, in order to replicate a curved trajectory.

Why is it important?
The occurrence of wheel squeal is attributed to the lateral oscillation of the wheel, which arises from lateral creepage.The study's findings indicate the existence of unstable oscillations that were observed and examined.The occurrence of unstable oscillations arises from the presence of sliding within the contact zone. The phenomenon of lateral movement, commonly known as lateral creepage, occurs in this context.
