What happens when a car crashes into a solid barrier?
When a car crashes into a solid barrier, the outcome depends in part on the size of the front end.
How is a barrier oriented in a crash test?
The barrier shall be oriented with its front face 10° (±1°) relative to the perpendicular of the longitudinal axis of the test vehicle. Initial vehicle contact will be on the steering column side and the front of the vehicle shall overlap the face of the barrier by 40% ± 25 mm.
Why do we need a deformable car barrier?
The choice of a rigid barrier was governed by the need for repeatability and the lack of a deformable element, simulating the force/deflection characteristics of a representative car front-end structure. Having this deficiency in mind, some additional car-to-car crash tests have been carried out.
Which is bigger a car or a barrier?
If one car’s front end is long enough to crush twice as much as another car’s in a barrier crash at the same speed, its restrained occupants will experience half as much force as the people in the smaller car because it takes them twice as long to stop.
What happens when a car crashes into a barrier?
Now watch what happens when the car crashes into a barrier.The front end of the car is crushing and absorbing energywhich slows down the rest of the car. In this case,it is the steering wheel and windshield that applies the forcethat overcomes the dummy’s inertia. Crash-Barrier Chalkboard
