Car Crumple Zone Diagram

The crumple zone on the front of these vehicles absorbed the collision impact.

Car crumple zone diagram. Crumple zones they increase the time taken to change the momentum of the driver and passengers in a crash which reduces the force involved. Side view of a crashed car showing the crumple zones. A misconception about crumple zones sometimes voiced citation needed is that they reduce safety for the occupants of the vehicle by allowing the body to collapse therefore risking crushing the occupants. Call it what you like we re all aware of the modern car having these zones at the front and rear.

Surrounding those parts with crumple zones allows the less rigid materials to take the initial impact. Newton s laws are very important when it comes to car safety. Crumple zones are designed to absorb impact energy during a collision so that most energy is dissipated across these zones and not in the passenger compartment. The strong outer shell comes with front and rear crumple zones that help to absorb the impact of a crash increasing the safety of the car s occupants.

If a car had no crumple zones like the big solid old 1950s cars the car would be more rigid on impact and the forces on the occupants inside the cabin become higher. The higher the forces that act on a human body in a car crash the higher the risk of injury and death. Crumple zones have more than one purpose. Vehicle safety features have come a long way over the years.

These two illustrations above depict passenger seat construction left and a car dashboard console with driver and passenger airbags deployed. Features such as crumple zones seat belts and airbags all provide protection if you have a crash however active safety assist technologies which can prevent a crash from occurring are now a significant point of differentiation. When there is a car crash the car its contents and the passengers decelerate rapidly. Newton s laws and car safety car safety features.

Crumple zone deformation zone or crush zone. The crumple zone also known as the crash zone is the area in a car where the energy of the impact is absorbed and reduced thus preventing it from being transmitted to the occupants and keeping passengers safe during accident. Try the following experiment to see how a crumple zone works. The diagram above shows a compact economy car s crumple zones and crash impact absorbing capabilities when the collision energy is dispersed through the unibody frame structure.

In fact crumple zones are typically located in front of and behind the main body of the car which forms a rigid safety cell compacting within the space of the engine compartment or.
