Abstract
Modifications brought to APROD dummy since the Eighth ESV
Conference in Wolfsburg are presented and explained. They result in
new features of biofidelity and of dynamic response as regards the
main body segments. Simultaneously, the injury criteria to be
associated to the use of APROD in lateral collisions are discussed.
They include in particular the case of the abdomen. Besides, the
new head and neck assembly is matched to HIC 1500 and the thorax to
a relative deflection criterion which is commented upon.
Since the Eighth ESV Conference, numerous studies concerning
biomechanics and future dummies have been performed. In particular,
many researches were carried out in the framework of contracts with
the E.E.C. They resulted in more precise requirements to be met by
dummies; besides, their dynamic response was investigated. The
APROD dummy underwent consequently several modifications; the
purpose of this paper is related to this development and its
consequences on the possible injury criteria when using the
APROD.
Technical Evolution - three main grounds triggered the changes
brought to APROD; they concern biofidelity, accidentological data
and mechanics, respectively.
New biomechanical data are available which define the human head
response to direct lateral impact, and which define the head
kinematics, due to the neck response, when the body is pushed
sidewards. To a certain extent, the APROD head and neck assemblies
were modified accordingly.
Accidentological data showed the weight of abdominal injuries in
lateral collisions. The abdominal section built by TNO from APR
data is able to detect the likelihood of injuries and was
incorporated with APROD body.
Dynamic testing showed some shortcomings of the previous APROD
thorax. A mechanical analysis of the thorax response was performed
which resulted in structural modifications.
