The control of wheel/rail noise and forces through friction modification
The growing public awareness of environmental issues has placed considerable demands on railway authorities to reduce any excessive noise levels associated with the operations of the rolling stock. The current study, which has been conducted in the Hunter Valley Region of the Rail Infrastructure Corporation, has examined two main causes of the considerable noise that can be generated by the wheel/rail interaction, namely: flanging of the wheels on the rails that occurs in sharp radius curves and wheel “squeal”, which can arise from the slip/stick action of wheel sets engaging sharp radius curves. The results obtained have shown that the appropriate application of lubricants and friction modifiers can lead to marked reductions in the wheel/rail noise levels. The work has also shown that the lateral wheel loads produced during curve negotiation are also reduced substantially by the application of friction modifiers to the running surface of the rails.
