When an understanding of complex motions associated with various accidents is required, computer simulation is an invaluable tool, which allows the modeling and visualization of rollovers and collisions. In addition to vehicle accidents, computer simulation can also be used to create many other systems of masses and contacting surfaces, such as a toppling light pole after it has been struck. Simulation can reconstruct the motion of a falling I-beam at a construction site or determine the jack-knife behavior of an articulated truck. Such modeling can determine the speeds and forces during an event and can even predict how an event accident could have been avoided.

Questions Answered

We have extensive experience in many aspects of computer simulation including:
  • 3-Dimensional modeling using the Articulated Total Body (ATB) , a U.S. sponsored simulation code
  • Simulation of kinematics of human joints and vehicle hitches
  • Use of other computer software including Mathcad & Matlab

Case Examples

SUV Rollover:
An SUV lost control and traveled over a portion of highway guardrail before rolling down an embankment, destroying the roll cage's integrity. The defense theorized the driver was killed by intruding guardrail posts as the SUV rolled along the guardrail, and that a stronger roll cage design would not have protected him. We reconstructed the accident using computer modeling, which disproved the defense's theory and showed that the driver would have survived if the roll cage had been designed stronger.
