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.
Dr. Irving Ojalvo was, at the time of this article's publication, the Chairman of Technology Associates (www.technology-assoc.com), a forensic engineering firm with offices in New York City and Connecticut. The firm's technical personnel, all of whom have advanced degrees, perform accident reconstruction involving issues of biomechanics, mechanical, traffic, and human factors engineering.

Forensic Engineering Experts: Lighting & Visibility
A person’s interaction with his environment comes largely from visual cues. Without this information, a pedestrian can trip over an unseen object or a driver might not detect a dangerous situation. In order to avoid these hazards, a person requires adequate lighting and should be provided with appropriate illumination for a given task.

Forensic Engineering Experts: Motorcycles
Motorcycles, like passenger cars, are capable of high speeds and must share the road with other vehicles. However, unlike passenger cars, motorcycles are capable of rapid accelerations, offer little protection to the operator during a collision and require special skills to maneuver effectively.

Forensic Engineering Experts: Products Liability
An end user of a product expects that a given product will not only function as intended, but will be safe from non-obvious hazards. Based upon decades of experience with mishaps during use of common and specialized equipment, thousands of standards have been developed for many consumer products and industrial equipment. Numerous organizations exist, e.g., ANSI, ASTM, SAE, and ASME, that regularly review and update these standards.
