Abstract

Squeal noise is generated by railway vehicles transversing tight curves. This squeal has always been noticed as one of the most disturbing noise sources of railway systems. At present we cannot predicted squeal noise that is influenced by a large number of dependent parameters. In this study, we performed structural analysis to find out the frequency of the wheel and also measured squeal noise at Seoul subway line 1, line 2, line 4 for domestic EMU(Electrical Multiple Unit).
