TITLE: Propagation of Sound Through Rail Train Braking Infrastructure for Acoustic Actuation
Abstract
Exploring the feasibility of acoustic wave propagation through the infrastructure of freight train pneumatic brake pipe systems. Traditional air brake systems suffer delays due to the potential for very long freight trains, which this research addresses. By examining the transmission characteristics of acoustic signals within these pipes, this investigation focuses on identifying optimal frequency and amplitude ranges for reliable propagation as well as analyzing how signal shape and behavior evolve along the pipe under pressurized conditions. A review of different types of braking systems currently used in the locomotive industry is included using simulation-based analyses of acoustic wave mechanics. Findings aim to establish baseline parameters for potential acoustic applications in the actuation of the train braking system.
