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.
We have extensive experience in many aspects of computer simulation including:
Through scientific analysis, we can help you answer pertinent questions such as:
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.
Water Wagon Rollover at Landfill:
The driver of an articulated water-tanker tractor was injured when the tank trailer rolled onto its side, causing the tractor to roll with it, crushing his arm. The plaintiff claimed that the articulating hitch that was used by the manufacturer was inappropriate in that it did not allow the water tank to roll over independently of the tractor. Using a 3D computer simulation, we demonstrated that the proposed design change could not have prevented the accident.

Forensic Engineering Experts: Fork Lifts & Skid Steers
Forklifts, industrial trucks, skid steer loaders, bobcats and other similar material-handling machines are often difficult to maneuver and susceptible to a wide range of accidents. Their nature exposes operators and nearby co-workers to falling loads, crushing hazards and lading dock falls.

Forensic Engineering Experts: Structural Analysis
Structural failure can often produce catastrophic results. In many cases, the damage seen after the accident is not indicative of the cause of the initial failure. Fortunately, based on physical evidence, an investigator can frequently determine how and why a structure failed.

Welcome to the third and final post in our multipart series of blog posts about a young boy's fall and serious injury at a public playground. In our first post we gave a brief overview of the incident and our investigation. In the second post we discussed some of the safety standards applicable to public playgrounds. In this post, we will examine some of the impact-absorbing playground surfaces available to protect children at playgrounds from injury. If you would like to read the first two posts, they are available here and here.
