The influence of the wheel web shape and rail gauge on rail corrugation was studied,based on the viewpoint of the frictional self-excited vibration of a wheel-rail system leading to rail corrugation.Several finite element models were set up and used to study the occurrence propensity of the unstable vibration of the wheel-rail system using the complex eigenvalue method.Results show that the wheel web shape has some impacts on rail corrugation and the straight web wheel can restrain it to some extent.The rail gauge has few impact on self-excited vibration of a wheel-rail system with S-shape web wheels.The rail gauge has some impact on self-excited vibration of a wheel-rail system-with straight web wheels,when using the specific gauge (1 430 mm),a new wheel-rail system whose frictional self-excited vibration will not occur is got.
