SMART car crash (TEST)
The National Administration road safety traffic NHTSA conducts two types of crash tests under the New Car Assessment Program.
the impact end 35 mph - 35 mph to 56 kph, the car goes straight in a solid concrete barrier, equivalent to a car moving at 35 mph hit another car of comparable weight moving at 35 mph .
side impact 35 mph - A sled 1368 kg 3,015 pounds with a deformable bumper strikes the side of the test sled vehicle tires are inclined The test simulates a car passing through an intersection being swiped by a step drive a red sled makes the light moves to 38 5 mph, but when you do the calculation, it is equivalent to a lateral shock of 35 mph because of the way the wheels are inclined on the sled.

Painting Crash Test Before the crash-test dummies are placed in the vehicle, the researchers apply paint to the different colors of paint are applied to the parts of the body most likely to hit during a collision knees mannequin dummies the face and cranium areas are each painted with a different color in the next photo, you can see that the blue paint of the face of the dummy is smeared on the airbag and that his left knee painted red hit the column direction.

If researchers noted particularly significant acceleration in the accelerometer data to the head of the dummy conductor, paint brands in the car indicate which body part hit any part of the vehicle inside the cabin This information helps researchers develop improvements to prevent this type of injury in future accidents.

Now let's take a look at a front-shock test 35 mph.
vehicle configuration The picture below shows a pickup truck that is ready to plant mannequins were placed in the car and are in position All instruments on the car and dummies were hung and tested ballast is added to the car for the accident vehicle weight -test - and the distribution of that weight - is equal to that of a fully loaded a vehicle speed sensor has been mounted on the vehicle and positioned so that it passes through a head reading as well as the car hits the barrier.

There are 15 high-speed cameras including several under the car pointed upward They shoot around 1000 fps Next, the car is moved back to the gate and ready to plant a pulley mounted on a track, pulls the car over the track car hits the barrier at 35 mph it takes about 0 1 seconds from the time the car hits the barrier until it stops.
After the crash Leave a look at some pictures This car has four stars for both front occupants in the crash-test.

As you can see, the front of the car is completely crushed after testing What is good because the car has to be crushed and reduced to absorb kinetic energy and stop the car.

The front of the van crashed up the front wheels, which are driven in the accident, the truck was 23 inches 58 cm less.
