DyMESH 3-D Collision Simulation
This simulation is an illustration of an underride collision between a 2002 Acura 3.2TL and a School Bus. The driver of the School Bus is stopped at the intersection, with their foot resting lightly on the brake pedal. The inattentive driver of the Acura reacts too late and applies hard braking in an unsuccessful attempt to avoid running under the back of the bus.

This simulation illustrates the use of EDVDS for design
evaluation. The combination vehicle (truck with empty
trailers) is undergoing an alternate ramp traversal test at

EDVSM Staged Rollover # 1 - Stunt Show
This event shows a rollover simulation using EDVSM. A Buick
Skylark is approaching a ramp at 65 mph in a hard right
turn. As it hits the ramp, the vehicle quickly rolls over,
flipping and rolling several times. The simulation shows
the vehicle coming to rest on its wheels with body
damage to the roof and front end. (Download time for this
1.6 MB movie is about 2-10 minutes.)

EDVSM Staged Rollover # 2 - FMVSS 208 Rollover Test
This EDVSM simulation is of a FMVSS 208 test of a Chrysler New Yorker.
The vehicle was placed on a dolly at an initial roll angle of 28 degrees. The dolly
moves at a speed of 30 mph and stops suddenly, causing the vehicle to
separate and experience an initial lateral velocity of 30 mph. The major roll moment
occurs when the vehicle's right-side tires contact the pavement with a tire slip angle
of 90 degrees, thus inducing the rollover. This simulation is played at 1/2 real-time speed.
(Download time for this 2.0 MB movie is about 5-13 minutes.)

EDVSM Real-world Crash Involving an Off-road Rollover
This EDVSM simulation illustrates the EDVSM body model for studyng a real-world, off-road rollover. A 1998 Volkswagen Jetta loses control while traveling at 47 mph on a downhill curve resulting in the vehicle leaving the roadway. The vehicle travels over the sidewalk and down an embankment into the lower parking lot. The rollover occurs as due to significant vertical tire forces at the left front tire at the same time the vehicle sideslip angle was approximately -45 degrees. (Download time for this 1.6 MB movie is about 2-10 minutes.)

EDSMAC4 Staged Collision Simulation
This EDSMAC4 simulation shows a staged side-impact crash test between a
Ford Thunderbird and a Chevrolet Celebrity. The Ford Thunderbird started from a
rest position and accelerated up to a speed of 35 mph prior to impact. A Chevy
C-10 pickup was used to push the target vehicle up to a 10 mph pre-impact
velocity. (Download time for this 1 MB movie is about 2-7 minutes.)

Combined Simulations Crash Sequence
This example combines EDSMAC4, EDVSM and EDVDS simulations together to create a complex crash sequence involving passenger cars and a commercial vehicle. EDSMAC4 was used to simulate the 3-car crash and resulting vehicle damage. EDVSM was used to simulate the post-impact motions, including airborne vehicles off the cliff. EDVDS was used to simulate the steering and braking avoidance maneuvers of the commercial vehicle. (Download time for this 2.9 MB movie is about 8-20 minutes.)

EDSMAC4 Multi-vehicle Intersection Crash (Overhead View)
Although this crash would probably not happen in real life (we hope!), this simulation reveals the raw power
of EDSMAC4. The user spent only about 10 minutes to set up and execute this entire multi-vehicle crash
sequence, and another 30 minutes to produce the video. (Download time for this 1.7 MB movie is about 3-10 minutes.)

S-turn (lane change) Maneuver Simulation
This simulation shows a vehicle performing a lane change manuever using the HVE Driver Model to follow
a predetermined path. The vehicle is a Generic Class 3 Passenger Car traveling at 55 mph. The forward acceleration
of the vehicle is 0.1g. The path curvature is 1132 feet. The lane change manuever occurs over a 3 second time span,
preceded by 1 second of acceleration. (Download time for this 1.6 MB movie is about 2-10 minutes.)

Winding Road Simulation
This simulation shows the use of the HVE Driver Model to determine driver inputs required to follow a long and
winding road. The desired path for the vehicle is indicated by the target vehicle images. The tractor is towing a
loaded 45-ft semi-trailer. This is a good example of an attempted maneuver that the vehicle is not able to perform
at the given speed and steering correction rate, as suggested by the large path error. (Download time for this 5.5 MB movie is about 10-25
minutes.)
