The Impact of HVE Simulation Technologies

HVE has revolutionized the technologies used to reconstruct motor vehicle crashes. Several applications of these technologies are presented in the examples below, which range from a multi-vehicle collision involving a commercial tractor pulling double trailers, to a curb-tripped rollover resulting from an intersection collision between a pickup and an SUV.

Click on an image to explore a detailed reconstruction of each scenario, including the issues and answers provided directly using HVE simulation technologies such as the EDSMAC4 Multi-vehicle Collision Simulation Model, SIMON 3-D Vehicle Dynamics Simulation Model and the DyMESH 3-D Collision Model. You'll also discover simulation set-up details, output results and high-definition simulation movies from various camera viewpoints.

MULTIPLE IMPACT • A 2005 Ford 500 SEL was northbound on a two-lane highway approaching a bridge when it drifted onto the shoulder and collided with a bridge abutment, coming to rest in the northbound lane. A 1997 Land Rover Discovery was following the Ford and collided with it. The second collision sent the Land Rover into the oncoming lane, where it collided with a southbound Freightliner Columbia pulling a set of doubles.

WHEEL IMPACT • A Peterbilt 2-axle tractor pulling double belly-dump trailers uphill over a narrow bridge crossed the centerline in front of an approaching Ford sedan. Both drivers reacted, but impact occurred between the left, rear tractor drive wheels and the left, rear corner of the Ford sedan.

SECONDARY IMPACT • A 1984 Ford F-150 pickup towing an empty utility trailer approached an intersection and turned left in front of a 2005 Jaguar S-Type sedan, resulting in a collision between the front of the sedan and the right side of the pickup. A secondary collision occurred between the rear of the sedan and the right side of the trailer.

CURB IMPACT • A Ford F-150 pickup towing a heavily loaded utility trailer fails to obey a stop sign and crashes into the driver's side of a Suzuki Grand Vitara SUV crossing through the intersection. The impact causes the SUV to rotate and skid until the right rear tire sidewall impacts a curb, tripping the SUV. It rolls over, coming to rest on its side in a grassy field.

These are just a few applications of the advanced simulation technologies available in the HVE (Human-Vehicle-Environment) simulation software suite used by motor vehicle crash reconstructionists in over 30 countries.
