Demystify those who are conscientious, car test fake people

IIHS is a referred to as the INSURANCE INSTITUTE for Highway Safety. There is a very systematic and professional collision test in Europe and the Americas, and the models of the safe performance index are starred to each manufacturer's model. Division, these security indexes have great help to the sales of the car, which promotes the investment in safety research in various cars. China's CNCAP believes that everyone has already heards even more known, from today we will bring you a series of articles in the US IIHS Collision Center. As the first phase, let's first understand the car test fake.

IIHS VRC (Vehicle Research Center) is located in central Virginia, covering an area of 22,000 square feet, in 1992, has three runways. Two runways are 600 feet, which allows full-size pickup to accelerate to 50 miles. The third runway is 200 feet, which can perform a 25 mile-speed collision test of speed. IIHS VRC is the first collision testing mechanism in the United States using a hydraulic motor propulsion system. The use of hydraulic nitrogen push the hydraulic motor drive the cable to accelerate the test vehicle to a predetermined collision speed.

Calibration of the car test fake : Car test dummy calibration laboratory manager Marvin Hatchett said to ensure that the state of the dummy in two tests is consistent, making collisions Repeatability of the test is achieved, and the dummy must be calibrated after each collision.
The car test dummy calibration is mainly calibrated to the dummy internal sensor. The sensor calibration is the process of rejection using standard appliances with high levels of high levels to establish a corresponding relationship between sensor outputs and losers. Also determine the error relationship under different conditions of use. When calibration is calibrated to the dummy, including: Head drop test, front impact test, knee collision test, post collision test.

The size and type of the car test dummy:
The car test fake person can be divided into three types according to the purpose: positive collision car test fake people, side collision car test car test fake people, rear collision car Test a dummy. The size of the car test dummy is also from
6-month-old baby dummy to 95 percentile adult fake. In frontal collision test, IIHS used 50% of Hybrid III male dummy, height of 5 feet 10 inches (about 177.8 cm), with a weight of 172 pounds (about 78kg). This car test dummy is equivalent to adult male in medium body.
In the side collision test, IIHS uses 5% Hybrid III female car test fake people. This dummy has 20-40 sensors. The above sensors include accelerometers, dynamometer, and bitMovement (measuring rib shift), etc.
Biorid is a car test dummy for whipping tests. It has cervical joints and corresponding sensors that provide more useful occupant cervical spine damage data than the Hybird III car test dummy that is collided with the front.

The price of the car test dummy:
We have been learned in the Changan Auto Collision Laboratory that Changan is about RMB 1 million for whipping test.IIHS said that a fully equipped car test fake is about $ 200,000.It seems that the price of the car test dummy used in IIHS is still high.

The most important car crash laboratory is not a runway, not a propulsion system, but the car test fake person who is conscientious without regrets.It is precious data provided by these car test dumpers to make car safety in recent years.
