Virtual Vehicle Safety Assessment Step 2: Open Source Digital Human Body Models and Crash Testing

The objective of ViVA II was to complete the development of the world’s first open access virtual model, ViVA F50, designed for simulation of vehicle accidents. This objective was completed.

An additional objective was to use ViVA F50 v2 for development of a new unique crash-test dummy representing an average female for evaluation of whiplash protection produced from knowledge gained from simulations. This objective was completed.

Both these achivements are now being administered and developed further in the EU-funded project VIRTUAL.

Results

ViVA F50 v1, which corresponds to an average female, has been improved through the addition of active muscles, https://www.chalmers.se/en/projects/pages/openhbm.aspx.

A computer-based construction CAD (Computer Aided Design) model, which can be used for manufacturing of a physical female-based dummy, has been designed, http://crashscene.se/f50flogard/. Both the ViVA F50v2 and CAD model constitute the starting point for the models being developed in VIRTUAL.

ViVA II has contributed to an increased interest in open source code in the area of Human Body Modeling and Virtual Crash Testing.

AN AVERAGE FEMALE HEAD-NECK FINITE ELEMENT MODEL WITH REFLEXIVE NECK MUSCLES

Several factors potentially contribute to the risk of whiplash injuries; one of them is the neck muscle activities. Muscle activities in the neck have been shown to influence the head-neck kinematics during whiplash-like rear impacts. Thus, it is necessary

Biofidelity Implications for Developing Design Concept of Female Physical Test Device based on Human Body Simulations

Studies have shown that most of the whiplash injuries are caused by the rear crashes [1,2], and therefore, there is a need for evaluate restraint systems in this specific type of crash. Currently, BioRID is the most biofidelic Anthropometric Test Device
