Abstract:Occupied volume integrity (OVI) refers to a
passenger railcar’s ability to preserve space for
passengers and crew during an accident. The
Federal Railroad Administration’s (FRA) Office
of Research and Development (R&D) is
sponsoring research investigating OVI. The
results of a series of tests have been published
in an FRA Report [1]. This research forms the
basis for establishing alternative OVI evaluation
procedures. The alternative procedures permit
an analysis to be validated with data from an
elastic test. The validated analysis may then be
used to extrapolate the behavior of the subject
car under destructive load conditions, without
conducting companion destructive testing.
