Rail Wheel Squeal – Some Causes and a Case Study of Freight-car Wheel Squeal Reduction
Rail wheel squeal on curves in rail track is a source of potential noise annoyance to residents adjacent to rail lines. For one private rail freight operator, wheel squeal was causing repeated complaints from neighbours. Wheel squeal can be caused by the wheel-tyre to rail-top interaction and the wheel flange interaction with the gauge face of the rail (more like a screech). This paper describe...
متن کاملExperimental and theoretical investigation of railway wheel squeal
The tangential contact forces that arise at the interface between the wheel of a railway vehicle and the rail provide all the traction, braking, and guidance required by the vehicle. These forces are the result of microslip or creepage and can become unstable exciting vibration of the wheel, particularly at frequencies corresponding to the wheel’s axial (and radial) modes. Although theories exi...
متن کاملImpacts of Wheel–rail at Railway Turnouts
Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh-
Timoshenko beam elements. The ra...

متن کاملA Study to Predict the Development of Wear for the Wheel/interface of a Railway Track
The train transport is often confronted with greatly repeated changes in scope, vehicle travel well-being and transport safety because of the adjustments of wheel and rail profiles. These problems are frustrating and threatening. Thus, there is a requirement for an approach to predicting the wear of wheel/rail to tackle these problems. A new theoretical ground is broken through the build-up a m...
