Improved methods for the separation of track and wheel noise components during a train pass-by
Improved methods for the separation of track and wheel noise components during a train pass-by
Experimental techniques are described that aim to allow the wheel and track components of rolling noise to be separated from pass-by measurements. These are based on Advanced Transfer Path Analysis, Pass-by Analysis, and a method based on the TWINS model. Improvements to these methods and their experimental validation using field tests are described. Initial comparisons are made for two test cases, a metro train running at 60 km/h and a regional train running at 80 km/h. The three methods agree reasonably well in terms of overall trends. The largest differences are found at low frequencies where the two exper-imental methods give similar levels for sleeper and rail vertical components whereas the TWINS model gives a larger distinction between them.

Abstract
Experimental techniques are described that aim to allow the wheel and track components of rolling noise to be separated from pass-by measurements. These are based on Advanced Transfer Path Analysis, Pass-by Analysis, and a method based on the TWINS model. Improvements to these methods and their experimental validation using field tests are described. Initial comparisons are made for two test cases, a metro train running at 60 km/h and a regional train running at 80 km/h. The three methods agree reasonably well in terms of overall trends. The largest differences are found at low frequencies where the two exper-imental methods give similar levels for sleeper and rail vertical components whereas the TWINS model gives a larger distinction between them.
