Paper 438 Acoustic rail grinding measures of long term

An acoustic grinding method was developed to address the GIC following a period of research and development. Field trials of different grinding techniques were undertaken at a number of locations around the network and inside the tunnels, which then led to the creation of a High Speed Grinding Strategy for ECRL.

ACOUSTIC PROPERTIES OF INDUSTRIAL MACHINERY

This motion produces “sound.” When machines are built to improve man’s abilities, the situation becomes worse, because machines are usually noisier than people. In fact, the situation had become so bad that on May 17, 1969, the occupational noise-exposure regulation of the U.S. Department of Labor went into effect (Walsh-Healey Act)

Grinding Machines an overview ScienceDirect Topics

Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min −1, although in high-speed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding applications are cylindrical grinding and surface grinding.
