Another organization to conduct crash tests of cars, which we will consider today – NHTSA (National Hihgway Traffic Safety Administration) – The administration of the national transportation security. What is the rating system they use? This organization uses a 5-star rating system. Five stars means a high degree of protection, one star is a low degree of protection. What is included in this ranking? Cars as well as in the IIHS does not have the overall evaluation, and estimated degree of protection for the driver and passenger. In the frontal test, than estimated in the front seat passenger, side impact is considered a passenger behind the driver. What tests are conducted for the evaluation? 1. Frontal collision.

2. Lateral collision with a car. 3. Testing the car on the possibility of revolution. What test conditions and that this check? 1.

Frontal impact: The head-on situation collision test car with the car takoyzhe weight and size. The clash is the full width of the front of the avtmobilya, at a speed of 56km / h. Measure the protection of the head, chest, left and right legs. As a driver and passengers are considered men of medium build. 2. Lateral collision with a car: We consider the situation when in the test car enters the other vehicle at a speed of 62 km / h, the weight of the car equal to 1368kg. Place of contact – the lateral portion of the test vehicle in the driver’s and passenger’s door. Measurements of protecting the head, chest and pelvis, performed at the driver and passenger seated behind the driver. The size and weight of the driver and passengers are the size of an average adult. 3. Testing the car on the possibility of revolution: In this study examined the probability of coup car, with a sharp change in trajectory at a certain speed. We consider the situation when the motion in a straight line at speeds of 56 to 80km / h, the driver turns the steering wheel sharply to the left (turn of the wheel about 270 degrees), and a second later a sharp turn at the wheel right (turn of the wheel about 540 degrees).
