In many auto accident investigations, it is necessary to know not only the speeds and motions of the vehicles involved, but the causes of injuries suffered by their occupants as well. Such investigations seek to answer biomechanical questions regarding occupant ejection, effects of seatbelt use, airbag deployment and body-interior impacts. Such answers can sometimes be found through simple analyses, or they may require advanced three-dimensional simulations and computer modeling techniques. Once an analysis of this type is complete, it is often necessary to generate drawings or animations to communicate the findings to a judge, jury or mediator.  Our biomechanical engineers have the ability to handle all aspects of such an investigation, from the initial accident reconstruction, through computer simulation of the occupant motion and the resulting forces and loads.
