This simulation is an illustration of a SIMON with DyMESH simulation of an offset barrier crash test. The Ford Explorer is driven into the barrier at 35 mph. The moving camera view used in this movie is from HVE v5.00, where the camera has been assigned to follow the approach of the Explorer into the barrier.
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.
Motorcycle Collision Simulation This simulation is a simple, straight-forward application of EDSMAC4 to simulate the pre-collision phase of a motorcycle collision. For more information, please refer to the Technical Session of the June 2001 EDC Technical Newsletter.
EDVDS Alternate Ramp Traversal Simulation
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 a speed of 30 mph. The purpose of the test is to study the effect of torsional frame compliance on vehicle handling. The ramps are 9 ft long and 1 ft high.
EDVDS Tractor-trailer (Triples) Rollover Simulation
This EDVDS simulation shows the same Freightliner FLD-120 towing three trailers at 55 mph. In this case, the vehicle is heavily loaded, and responds to a heavy sinusoidal steering input.
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.
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. For more information about this simulation, refer to "Applications and Limitations of 3-Dimensional Vehicle Rollover Simulation"
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. For more information about this simulation, refer to "Applications and Limitations of 3-Dimensional Vehicle Rollover Simulation."
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.
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.
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.
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. For more information about this simulation, refer to "The Simulation of Driver Inputs Using a Vehicle Driver Model"
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. For more information about this simulation, refer to "The Simulation of Driver Inputs Using a Vehicle Driver Model"
EDVSM Handling Simulation Over Irregular Terrain
This EDVSM simulation shows a VW Cabriolet driving down a hill and turning right onto another road.
These roads were created using a total station survey and downloaded into HVE. It took a total of about 45 minutes to set up the simulation, execute it and produce the video output.
GATB Head-on Collision, Unrestrained Occupant Simulation This GATB simulation shows an unbelted occupant's response during a 15 and 20 mph head-on collision.
GATB Head-on Collision, Restrained Occupant Simulation This GATB simulation shows the same head-on collision as the previous simulation (see above), except the occupant is wearing a lap/torso restraint system.
GATB Occupant Ejection This GATB simulation shows the driver of the vehicle being ejected out the open passenger door due to the combination of the impact of the vehicle into a pole and the impact of the left rear wheel with the curb.
GATB Occupant Simulation This GATB simulation shows an unbelted occupant's response to an side impact crash . The body of the vehicle has been removed to allow the clear visualization of the motions of the passenger against the potential contact surfaces during the crash.
