Technology AssociatesIn many vehicle rollover 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 questions regarding occupant ejection, effects of seatbelt use, roof crush and body-interior impacts. Obtaining answers often requires advanced roof structural analyses and three-dimensional computer simulations of the rollover motion itself. When analyzing a rollover accident, computer simulation is an invaluable tool, which allows us to model rollover motion and roof crush and can be used to create animations of the accident.

Expertise

Questions Answered

We have extensive experience in many aspects of computer simulation including:
  • 3-Dimensional modeling using the Articulated Total Body (ATB) simulation code
  • Finite element roof crush analysis
  • Computer simulation and animation
  • An extensive rollover reference library
Through scientific analysis, we can help you answer pertinent questions such as:
  • What caused the vehicle to rollover?
  • How many times did the car rollover?
  • How does the stability index of the vehicle compare to others?
  • Could the accident have been avoided through a design change?

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 entire 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.

SUV Rollover Ejection:
A woman driving an SUV was seriously injured when her vehicle rolled over due to the negligence of another driver. The SUV driver was ejected because she was unbelted. The defense claimed that, based upon statistical studies, she would not have been injured if she had been belted. We demonstrated that, her major injuries were caused by her impact with the door interior and would have been inflicted even if she had been belted and had not been ejected. The case settled in the plaintiff's favor.

Forensic Engineering Experts: Pedestrians & Bicycles

By: Kristopher J. Seluga, PE

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.

Forensic Engineering Experts: Golf Carts

By: Kristopher J. Seluga, PE

There are roughly 9,000 golf cart related accidents requiring emergency room treatment in the United States each year. The majority of these accidents are related to either braking, cart rollover or passenger ejection. These problems are common to golf carts due to their open design, lack of seatbelts, poor braking capabilities and the uneven terrains they are driven on.

Forensic Engineering Experts: Retail Stores

By: Kristopher J. Seluga, PE

Supermarkets, pharmacies, home improvement, and department stores expose their customers to many potential accident sources such as floors and aisles, which can become unsafe, and display merchandize that can topple or cause tripping. To prevent such accidents from occurring, these establishments should maintain routine scheduled inspections to insure that unsafe conditions are detected and corrected before accidents occur.
