Type of car collision dummy

The collision test fake person is a test equipment with special structures made from a variety of special materials in accordance with the principles of ergonomics. The most important requirement of the collision test dummy is to be able to simulate the damage of the human body in the automobile collision process, and install a variety of types of sensors to facilitate the collection of various signals in the collision process. In addition, the collision test dummy needs to meet the requirements of repeated use.

What is the collision test fake?

The collision test dummy was originally used in research and development of aircraft ejection seats, parachutes. Later, it was gradually applied to the field of automobile collision safety. Collision Test Dumman is based on a large number of autopsy tests (this is also one of the reasons for the reasons for the reasons for collision test fake research and development cycle, but also including the structural parameters, but also each Mechanical response parameters. The design and processing assembly is made according to the large amount of data obtained above.

What are the collision test fake?

The collision test dummy began to develop in the 1960s. After more than 50 years of development, a variety of collision test fake people have already produced. The collision test dummy is mainly divided into adult fake people and children's fake people from the body size; according to the type of collision, it is divided into a positive collision test dummy and the side collision test fake.
Why is the dummy so expensive?

Car crash test dummy price is very expensive, a hybrid III 50th male fake person (the body size is basically distributed, 50th refers to the fake body size can cover 50% of the whole) Male body size) is equivalent to more than 100 sets of top-bearing iPhone7 for more than 8,000 yuan. It is mainly due to high cost of re-cost, and there is a need to be equipped with various test sensors. Take Word-Sid as an example, the dummy reserves more than 200 sensor channels. The price of the sensor and the corresponding acquisition system, processing software, etc. are expensive. Most importantly, the fake people used by the car collision are basically the international monopoly. Therefore, under the action of various factors, the price of car collision test fake people is high.

Is it unified?

In the NCAP evaluation system, the collision test dummy generally uses Hybrid III dummy, which is based on the European and American human body characteristics. The dummy used in China's automobile collision safety regulations is also a Hybrid III series fake person representing the human size of Europe and the United States.

C-NCAP uses foreign dumpers to have any reference significance for Chinese occupants?

For C-NCAP, when testing different models, unified Hybrid III series fake people do not have adverse effects on test results. However, the degree of damage caused by the fake people in the European and American human size is not fully reflected in China's human damage

. According to China-related scholars, the risk of injury in the head and neck of 50% of the male and neck in China is significantly larger than the European and American mixed III 50 percent fake, and China's 50% male chest injury indicators are small. So the damage indicators of Hybrid III series of fake people in C-NCAP can be discussed.

China is now carrying out research on Chinese male human size dumpers, including Tsinghua University, Hunan University The most representative it is, it is reported that Tsinghua University has developed the first generation of dummy based on Chinese male human sizes. However, if you want to truly replace the Hybrid III series in C-NCAP, not only to improve the quality level of the Chinese dummy itself, establish a practical Chinese human injury evaluation index, but also need to provide data reference for the new model research and development. Let the car enterprise accept a new dummy based on the Chinese body size, which is far away.
