Essay about Analysis of an Automobile During and After a Crash

wide lip that keeps the car from rolling off the side of the track). The car also has another set of

In the lab of “The Falling Eggs and Automotive Lab”, we had to design a protective device able to hold the egg and allowing it survive from the impact of hitting the ground from the top of the staircase. We did this lab to investigate newton’s Laws and prove how they work. In the lab, we have to observe the forces that act on the egg and evaluate the way they work. We do this lab with an egg to relate to a real life collision with a car. The egg is essentially the person and the device that the egg is in is the Airbag. We use our knowledge about airbags and apply that to this lab in order to make the egg survive and not crack.

Crumple zones are designed to absorb the energy from the impact during a traffic collision by controlled deformation. This energy is much greater than is commonly realized. A 2,000 kg (4,409 lb) car travelling at 60 km/h (37 mph) (16.7 m/s), before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 14.2 m (47 ft) crashing on to a solid concrete surface. Increasing that speed by 50% to 90 km/h (56 mph) (25 m/s) compares to a fall from 32 m (105 ft) - an increase of 125%. This is because the stored kinetic energy (E) is given by E = (1/2) mass × speed squared. It increases by the square of the impact velocity.

All metal surfaces are covered with foam padding. This structure must then meet rigid test requirements for bending and absorbing energy, such as would be required if a student’s body were thrown against the padded back. In addition, the equivalent of a seat back, called a “ barrier”, is placed in the front row of seats at the front of the bus.

The modern solution is something called a roll-cage. A roll-cage is a specifically engineered frame that is located in the passenger side of any race car. The purpose is to protect the car's occupants from getting injured if they're bodies are to sway to that side in a crash.

In a little over hundred years since automobile took hold of most people’s imagination, technologies design to make acceleration faster and reaching higher speeds have evolved. Despite charges, turbo charges, twin turbo charges or NOX, there are limits, which cannot be greater by land-based vehicle in terms of speed. Not the same can be said about the rather unseen parts of the automotive evolution. The only limitation to them is in connection with the human body ‘s ability to withstand rapid decelerations. It would be a lot easier to stop a car then to make it go faster otherwise. Whether they come in form of drum brakes or as disk, the brakes have been the horsepower’s companions throughout decades, each pulling

Damaged or rusted guards offer virtually no protection at all. In addition, hitting one at an offset (with the front left or right side of your car) causes severe damage to the car and may demolish the area occupied by the driver or right front passenger. Finally, a high-speed collision with the side of a trailer, which lacks an underride guard, can shear off the top half of a car.

how cool it is that cadavers have contributed to car safety. Cadavers are giving scientists a better

cceleration)). This law is in relation to crumple zones as the crumple zone decelerates and the force in which the person in the car would feel. Crumple zones and Newton’s Laws do relate to each other. As the car contents an object, it will cause the car to come to a stop or slow down gradually (1st Law). The car has a certain amount of force, which can be calculated by Newton’s 2nd Law. The result of the car’s mass and its acceleration. Because the force can be lowered by making the impact over a longer time, by making the crumple zone collapse slowly instead of an instant collision that barely decelerates, which means that the people in the car aren’t as badly affected as they would’ve been if there was no crumple zone the force is lessened

saying that even if a heavy load is in the car it can still go over

The aim of this report is to present the numerical analysis of human head response in a car accident in the sagittal plane. This is achieved by making oneself aware of the dynamic loading that arises at the instant accident occurs and the response of the human head to such loading. The response is usually biomechanical, which can be studied in terms of head acceleration due to the impact caused by the collision of the

Along with accidents not only comes a little headache or a broken bone, but injuries that stay with you forever such as whiplash and brain damage. Most brain damage incidents occur when you are involved in a side impact collision and the side of your head hits the glass (brain injury). Side impact airbags are just one of the many ways in which this type of life threatening injury can be avoided (whiplash). There is also whiplash, which hurls your head violently, and usually results in long term disability. Since whiplash is so hard to avoid, it can only be avoided by reducing the number of accidents on the streets. Also one of the most painful and most traumatizing injuries that we encounter in accidents are bone fractures, which occur in 65% of all accidents (Bush 11). So in turn by making these cars safer we can all avoid these painful, traumatizing, life-threatening injuries.

Baxton Technology Company manufactures surface automotive hoists which are used by garages, service stations and other repair shops to lift cars for servicing. Because of its design, quality of workmanship, safety features, ease of installation and five-year warranty, Baxton Lifts achieved a reputation as the “Mercedes” of the hoist industry and is considered a leader in automotive lift safety in Canada and United States.

The safety car appears when an accident happens. Drivers must drive behind the safety car slowly and they cannot overtake each other. When someone doesn’t obey the rules he has a penalty. It means that he must take a few seconds pit stop.

Accident frequency and severity affects make up the portion of customers’ premium that covers losses. Until recently, when determining liability premiums, vehicle make and model were not consideration. In the year 2000, there are over two auto insurers planned to raise liability rates on large size vehicles like SUVs, pickups and vans. This is based on vehicle safety and claims experience. A larger vehicle can cause injury and property damage; especially in the weight of car a ton or more could change the crash.
