3D FEM and MBS Coupling of Railroad Dynamics with Vibration of Surrounding Building Structures
thesis
posted on 2016-07-01, 00:00 authored by Chaitanya JoshiWith the advent of faster trains and changing railway technology, ensuring passenger safety
and comfort has become an important area of research in the rail industry. The abatement of
vibrations is also important and must be evaluated for new technologies. This research uses the
coupling of nite element modeling and multibody dynamics to model a three-dimensional track
system including rail, sleepers, ballast, substructure, and a nearby building. After conducting
an initial modal analysis of the rail and sub-structure, we run a multibody simulation of a
passing train to determine modal displacements and contact forces. We then reconstruct the
full displacement eld in a nite element software package and quantify the vibrations on
the building. The ultimate goal is to quantify the vibrations in the building structure and
understand the discomfort of the occupants.
