ABSTRACT: Using advanced digital signal processing, IEM analyzed truck vibration data and identified the specific vibration signature of hunting. This signature clearly differentiates hunting from signals generated by such transient phenomena as switch points and rough track. this approach has been confirmed through three distinct methods: simulation, analysis of hunting data developed by the TTX Corporation, and the analysis of actual truck vibration data gathered by a prototype system developed by IEM used in six test runs on AMTRAK cars operating in the NE Corridor.
