Objectives and content
During the last three decades, car manufacturers, their
suppliers, users organisation and legislative authorities
have manifested significant progress in the field of
passenger safety. Nevertheless, a great amount of
innovative and complementary work remains to be done yet
in order to reduce both number and the consequences of
certain critical injuries.
Car designers currently use anthropometric crash dummies
which are limited in their biofidelity and in their
application type (frontal, lateral). As a consequence,
they reflect important shortcomings with respect to a
real crash situation.
Increasing computational capabilities have allowed
designers to efficiently integrate simulation techniques
into the conception cycle of their prototypes. This is
also true for numerical dummy models, nowadays fully
integrated into the crash simulation procedures.
Unfortunately these models inherit the deficiencies of
their mechanical counterparts (e.q. biofidelity).
The next stage of the simulation obviously concerns the
modelling of an occupant, more representative of the
human body, which would provide a better understanding
and predictive capacities of the injury risks. This
would be beneficial both to passengers and pedestrians.
The development of such a model requires a deep knowledge
of the human body geometry, of its constitutive materials
and an experimental database needed for validation
purposes. Some comparable data may be found already in
the literature although their utility is limited due to
the non-homogeneity of the experimentation. It is also
the intention of this project to acquire and complement
the existing data.
The current project has three main objectives:
prepare human body models and utilities for the design
office use and consequently contribute to the security
aspects of road transport. Such analysis capabilities
would also be beneficial to the reduction of the accident
cost for the environment. It should be noted that other
transport types (aeronautic, railway) and other design
concepts such as ergonomics and comfort, which do not
necessary involve safety, may also benefit from to the
outcome of this project.
integrate the human dispersion issues (in terms of
geometry, behaviour, tolerance) in the design cycle.
accommodate within the framework of a European joint
project, the mutual concerns (production, prevention,
regulation) of the European community expressed in terms
of a reliable mathematical tool which can replace the
PMHS (Post Mortem Human Subject).
The consortium is mainly composed of car manufacturers
and their suppliers (whose prime concerns involve
passenger safety matters), research and educational
institutes whose activities are relevant to this project
(medical, PMHS tests, constitutive modelling, etc ...)
and finite elements code developers (namely crash codes)
whose products are currently used for crash simulation by
the major European car manufacturers. This project is
being registered as a EUCAR project.
