Why is the dummy in the car safe impact test than previously designed fat?

Automotive safety test has already passed a long road, which is no longer the age in the 1930s to imitate the body to abandon the abandoned elevator well (the earliest experiment is done with the body of people. The body is used to measure The human body is often the resistance of extrusion and the resistance of the extrusion and towing force in a car accident. For example, the weight is thrown into the body of the body in the channel of the elevator, the bone or the whole body can go. The acceleration of the heavy object can be simply calculated. The next step is to accelerate the acceleration in the body, tie the body on the car, and then do a diagonally collision or tumbling test on the experimental site).
The number of car accidents in the United States reached a new history, and it is largely due to the impact of the test dummy than before. Automobile manufacturers must use test fake people to prove the safety performance of vehicles before they enter the European and American market. They have become a super-complex human tool for collecting data and assessing risks. They are a group of true unknown heroes.
"The latest dummy can collect more than 130 channels of channels," CEO Chris O # 39 of the world's first-class fake manufacturer Humanetics, "said the amount of these data is 4-5 times a few years ago.
Humanetics works with insurance companies and academic research institutions to analyze these increasing data. By analyzing data, they can sort the most common damage types and people that are most likely to be injured.

Three kinds of people used for automobile collision:
1.50% human model: represents a medium body high of 177 cm and weight of 86 kg;
2.95%: representing height 188 cm and weight 108 kg large body;
3. 5%: representing a short body of 148 cm and 56 kg weighing.

In the NACP European Security Injection Test Center, HY-DrID3 is used to collect positive impact information children's model:
June human model: height 67 cm, weight 10 kg;
2.2 months : Height 76 cm, weight 13 kg;
3.18 months: height 83 cm, weight 16 kg;
4.3 years old: height 97 cm, weight 20 kg;
5.6 people: height 130 cm, weight 30 kg;
6.10 year old man: 138 cm high, 36 kg weighing.
Most of the human model is made from metal and plastic. The chest is steel, and the shoulder blade is aluminum. The basin bone is plastic, and the model is worth 15 to 3 million macks. 60 sensors.

The fake man model for the crash test is a small history:
1948 US Air Force first use human model for aircraft seat era;
In 1973, General Motors have developed a better human model Hydrid2;
Hydrid3 and the US side of the US side US SID;
In 1991, Europe launched its own side.

In order to adapt to the current situation of more and more overweight drivers, Humanetics began to develop obese dumns. One of the fake people reached 273 pounds (123.8 kg), the BMI index reached 35!
Analyst also said that the 50-year-old driver's serious injury will increase by 20%, and the 80-year-old driver will increase by 40%. The higher the risks, and the trend of stabilization growth is called.
In 2012, about 35% of the US population were obese populations, close to 70% of the human body overweight. Whether it is from a health perspective or an economic point of view, the price behind the increasingly serious obesity has made the United States overwhelmed. Moreover, more and more weight, make the car test dummy's data more and more.
"The chance of obese people in a car accident is 78% higher than the average person. The reason is that the obesity is in the case. The researchers of the Ili County Medical Center analyzed the 2000 to 2005 car accidents. It has found that the mortality of the drive of the moderate obesity has increased by 21%, while the mortality rate of the pathological obesity has increased by 56%.
Dr. Dietrich Jehle, chief, said: "The hit test dummy provides us with the precious body response data in a car accident, saving many lives, but these dumms can only use human individuals with standard weight."
