What Are Car Crumple Zones and How Do They Help Save Lives?
The Crumble Zone is one of the most important parts of the car, which absorb the energy from the impact during a traffic collision by controlled deformation by crumpling.
Auto safety has come a long way in the last few decades, and one of the most effective innovations is the crumple zone, also known as a crush zone. The cars body are made up of different parts, each with its own structure. The Crumble Zone is one of the most important parts of the car, which absorb the energy from the impact during a traffic collision by controlled deformation by crumpling. This energy is much greater than is commonly realized. The crumple zone is a structural safety feature mainly used in automobiles to absorb the energy from the impact during a collision by controlled deformation, and recently also incorporated into railcars. This kind of structure has a different design in the cars; hence one of the most important determinants of vehicle safety, the design of the Crumble Zone. Of course, keeping people safe in auto accidents isn’t as simple as making the whole vehicle crumple. Engineers have to consider many factors in designing safer cars, including vehicle size and weight, frame stiffness and the stresses the car is likely to be subjected to in a crash. For example, race cars experience far more severe impacts than street cars, and SUVs often crash with more force than small. As we have said, the task of the Crush Zone during accidents is to absorb energy from driving accidents; hence, in the event of a blow to the car, the region that has the most form of change is the car’s sacrificial area. In fact, this structure, by deformation, causes the energy from collisions to be neutralized and not damaged to other car structures. The Crash or Crumple Zones of the sacrifice is a form of design that has a functional role to be beautiful; therefore, experts in this field for designing and constructing such a structure, repeatedly carry out experiments involving the car with different objects. Typically, crumple zones are located in the front part of the vehicle, in order to absorb the impact of a head-on collision, though they may be found on other parts of the vehicle as well. According to a British Motor Insurance Repair Research Centre study of where on the vehicle impact damage occurs: 65% were front impacts, 25% rear impacts, 5% left side, and 5% right side. Some racing cars use aluminium, composite/carbon fiber honeycomb, or energy absorbing foam to form an impact attenuator that dissipates crash energy using a much smaller volume and lower weight than road car crumple zones. Impact attenuators have also been introduced on highway maintenance vehicles in some countries. If we are to look at the specialty of the Crumble Zone, we should know that this area, in its minimal state, should be able to absorb 2 kg at a speed of 60 km / h without any problems. Of course, this is a minimal indicator that car makers must take into account in designing their products; therefore, many large automotive companies, such as DS, have chosen more difficult standards for designing the sacrificial structure in their products.
