Response of Infinite Railroad Track to Vibrating Mass
Journal of Engineering Mechanics, 1988The resonant frequency of the railroad track is first determined by Timoshenko by modeling the track as a beam on a massless Winkler Foundation. The mass of the foundation and the vibrating load is not included in the formulation. Timoshenko provides a simple expression for the resonant frequency ωR=k/m, where k=the Winkler constant; and m=the mass per

Vibration and shock exposure of maintenance-of-way vehicles in the railroad industry
Applied Ergonomics, 2011The aim of this study is to investigate and compare vibration and shock measurements of maintenance-of-way vehicles used in the railroad industry for track maintenance and construction. Following international standards (i.e., ISO 2631-1: 1997) and professional guidelines the frequency weighted root-mean-square (r.m.s.) acceleration for each ...

Isolation of residential buildings from ground vibration from railroad
Journal of the Acoustical Society of America, 2016For residential developments near railroad tracks, ground vibration due to train movement is often a concern. Although there are usually no code requirements for vibration levels, ground vibration levels are often compared to the criteria recommended by the FTA; these criteria are sometimes explicitly included as part of the Conditions of Approval or ...

The Response of an Infinite Railroad Track to a Moving, Vibrating Mass
Journal of Applied Mechanics, 1990We examine vibrations that arise when a moving, vibrating load passes over an infinite railroad track lying on a Winkler foundation. Solutions are presented for both moving and stationary vibrating loads as a function of both the mass and driving frequency of the load as well as the physical properties of the track.

Whole-body vibration and ergonomic study of US railroad locomotives
Journal of Sound and Vibration, 2006Abstract US locomotive operators have exposure to multi-axis whole-body vibration (WBV) and shocks while seated. This study assessed operator-related and ergonomic seating design factors that may have confounding or mitigating influence on WBV exposure and its effects. Vibration exposure was measured according to international guidelines (ISO 2631-1;
