Injury Criteria in Lateral Collisions, When An Aprod Dummy Is Used
Published January 01, 1982 by National Highway Traffic Safety Administration in United States
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.
