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.

Expertise

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.

Event Data Recorders and Collision Investigation

By: Al Duncan

Event Data Recorders (EDRs) were first introduced by General Motors (GM) in 1974. That data was only available to GM; however, since 1994 more and more vehicle EDR’s have recorded data that can be gathered. The data captured can be imaged and is being used by vehicle manufacturers, law enforcement officers, and collision reconstructionists to better understand what is happening in a collision. In accident investigation, EDRs have the potential to provide independent measurements of crash data that would elsewise be estimated by reconstruction methodology.

Forensic Engineering Experts: Pedestrians & Bicycles

By: Dr. Irving Ojalvo

Pedestrian and bicycle accidents in the United States result in approximately 80,000 and 50,000 injuries each year, respectively. Though pedestrians and bicycles move differently, they share important characteristics as both have little protection during a roadway collision with a motor vehicle.
