Update of the FTSS RADIOSS Dummy Model Development Program
Robert Kant, FTSS
Anthropomorphic Test Devices (ATDs) are critical components
of vehicle safety development. Fulfilling the
role of a surrogate for a human occupant, the
ATD provides vehicle manufactures,
their suppliers, and consumer advocates insight
into how well the vehicle structure and integrated
occupant restraint systems
perform in reducing the potential for injury.
Mechanical systems and sensors packaged within
a humanlike form provide information
such as head accelerations, chest deflection
and femur forces which directly relate to injury
potential and safety ratings.
With the significant role finite
element analysis
plays in all aspects of vehicle structure
development, it is critical for FE engineers
to have a reliable and robust tool for predicting and preventing
injury to
the vehicle occupant.
Years of experience in physical product development,
occupant modeling and cooperative activities
with industry have led to an extensive
amount of dummy model
knowledge.
With the collaboration between FTSS and
Altair, this dummy model expertise is made
available to the RADIOSS community.
This presentation
will give an update of RADIOSS dummy model
developments and will
give insight into the process
for development and validation necessary
to develop highly accurate dummy models.
The
development of the new FTSS RADIOSS dummy
models relied heavily and coincided
with the evolving HyperCrash software
(v9 and now v10). As a result, the dummy
models have the highest level of compatibility
with the RADIOSS pre and post processing
tools in the HyperWorks suite.
