Analysis of the characteristics of the car test

Car test fake people also named collision test fake people. The collision test is initially used for ejection seats, parachutes, etc. related to aircraft. In 1960, the United States has developed a car crash test simulation dummy VIP, which is in SAE (Society Of Automotive Engineers American Automotive Engineer Association) standard for 50th simulation dummy (ie the 50% dummy - press Statistics, 50% of the US men's body weight and high physical parameters were specified in size, weight, and spring constant of the fake person.
 
With the in-depth of human injury mechanism in bionics and crash accidents, the research and development of simulating dummy has also developed: In 1971, Hybrid I was developed in 1971, here Based on the improvement of Hybrid I's head, neck, shoulder, spine, and knee, the configuration of the test instrument has been enhanced in 1972, and in 1972, in 1973 in FMVS208. Standard (Crew Collision Protection) The Hybrid II 50th Dakeman as a standard facility for the prevention performance of the occupant collision protection in the automobile collision test, and the standard Hybrid II test fake person in fake people in federal regulations In addition to the assay FMVS 208 standard In addition to the experimental fake people in China's injury indicators, there are also applications in FMVSS 212 and 301.
In 1976, General Motors made a lot of improvements to Hybrid II's neck, chest, knee, etc., and developed a mixed III type fake man Hybrid III closer to human body characteristics. Its installed data acquisition channel can be based on It takes more than 100, which greatly exceeds Hybrid II, and adapts to a more step-by-step research needs. And the improvement in the neck, etc., making the Hybrid III dummy's damage indicator value may be higher than Hybrid II, thereby put forward higher requirements for the occupant protection performance of the vehicle.
On July 25, 1986, the United States has revised 49CFR Part 572, which added a division on Hybrid III and regulations from October 23, 1986 to August 31, 1986. At the end of the day, the car collision test can choose to use any one of Hybrid II and Hybrid III dummy, and since September 1, 1991, Hybrid III will replace Hybrid II and to verify whether the vehicle meets the only FMVS208 performance requirements. Test dummy, later, due to some practical operating factors, decided to postpone the replacement date until September 1, 1997.

To further meet the study of automobile collision test and bioecologyThe needs of the investigation, the United States has developed a test fake family. In addition to the Hybrid II and Hybrid III, the Hybrid II and Hybrid III specified, it also developed the production of the kids SID and children's dummy who have collided with the car side.
European countries are also developing research and dumpers for car crash tests, and R16, which ECE (United Nations European Economic Commission) regulations (on the agreement of the unified conditions of the automotive belt and its posttle system certification) The fake person (the false person weighing 74.5kg, the height is 175 cm) in Europe, which is only used in the safety belt dynamic test in ECE RL6. Only high-speed photography is required to measure the fake people with high-speed photography [123 ] And the displacement of the chest. On the other hand, Europe has also developed a side collision EUROSID dummy and has been applied to collision tests, but there is no corresponding regulatory description.
About the trial of the car collision, there is no unified international standard so far, and countries use the most use of Hybrid II and Hybrid III, including Europe's Mercedes-Benz Motors, the world, etc. Big Motors use a large number of Hybrid II and Hybrid III type fakers in automotive collision test studies. According to the human type, the dummy can be divided into adult dummy and children's dummy. Adult fake people are divided into medium male dumpers, small body female dummy and big body male dummy. The most commonly used in the car collision test is the average body of the medium-sized fake person who represents the 50th percentage adult in Europe and America. In order to consider different human body shapes in the design, small body and big figure have been developed in accordance with the limit of the end of the population of European and American people. Small body female dummy represents the body of the 5th percentage of female adults in Europe and America; the big body male dummy represents the body of the 95th percentage of Europe and the United States. The height of the children's dummy, the weight is the average height and weight of children in the designated age group, regardless of gender.
According to the type of collision test, the dummy can also be divided into frontal collision dummy and the side collision dummy. There are now three collision dumpers for sale as a product: SID, EUROSID and BIOSID. These three fake people are developed according to the 50% adult male, and SID is a test fake person designated by the side collision test regulations in the United States. EUROSID is a test fake person designated by side collision test regulations in Europe, Japan and other countries. .
