ViVA - Virtual Vehicle Safety Assessment: Open Source Human Body Models adressing gender diversity

As part of the Swedish research project ViVA - Virtual Vehicle-safety Assessment: OpenSource Human Body Models addressing gender diversity, the OpenHBM project has been initiated to promote the development and distribution of Open Source Human Body Models for impact biomechanics research.

 

The aims for the OpenHBM project are to:

  • Establish a quality platform for development of  human body models, within the traffic safety research community, in order to enable access to models for
    • double checking of research results, and
    • novel applications.
  • Broaden human body models beyond the average male.

The first steps of this Open Source human body model project are to develop:

  1. A baseline LS-DYNA model of the average female,
    a. with biofidelic kinematics for omnidirectional acceleration loading typical of pre- and crash situations, and
    b. structured in such a way that body parts can easily exchange for more detailed/enhanced models.
  2. An anatomically detailed model of the cervical spine, with biofidelic response in rear end impacts.

The whole body model, deliverable no. 1 in the list above, is available for download here under the GPL v3 license:
In addition, the whole body model with detailed and simplified spine is available here under the LGPL v3 license:

A zip-archive with the anatomically detailed model of the cervical spine, deliverable no. 2 in the list above, as described in a paper (Östh et al. 2016) in the Journal of Biomechanical Engineering is available here under the GPL v3 license:

The model has been developed using single precision MPP LS-DYNA R7 and R8 binaries.

Tasks

The main tasks of the Virtual Vehicle Safety Assessment Step 2: Open Source Human Body Models and Crash Testing (VIVA II) project are to:

 

Task 1: Numerical Open Source HBM

1.      To implement the active feedback control to the ViVA II muscle model

2.      To establish tissue level injury criteria using ViVA II model

3.      To conduct reconstruction of rear world accident data using ViVA II model

 

Task 2: Gender Specific Protection Performance of Seat Design Concepts

1.      To evaluate the gender specific protection performance of seat design concepts

 

Task 3: ATD Design for Seat Model Verification and Whiplash Testing

To develop an ATD design for seat model verification and whiplash testing


The model has been developed using single precision MPP LS-DYNA R9.2 binary.
