Dangerous professional: car test fake people

Qinsun (Hong Kong) Co., Ltd. Auto Safety Information: The most dangerous professional: Car 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.
As the research and development of human body injury mechanism in bionic and crash accidents, the research and development of simulation 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., developed a mixed III fake man Hybrid III, which is closer to human body characteristics, which can be installed data acquisition The channel can be more than 100 as needed, which greatly exceeds Hybrid II, adapting 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 of Hybrid III, and in FMVSS 208 standards from October 23, 1986 to 1991. On August 31, 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 complies with FMVS208 performance requirements. The only test fake person, and later considering some practical operation factors, decision decision will delay the replacement date until September 1, 1997.

In order to further meet the research of automobile collision test and biomechanical research, 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.

Appendix of R16, ECE (United Nations European Economic Commission) regulations, European countries, ECE (United Nations Economic Commission) Regulations (Appendix on the Agreement of Unified Conditions of Automotive Safety Belt and Its Reidue System) 7 specified a fake person (the false person weighing 74.5kg, the height of 175cm) was used in Europe, which is only used for the safety belt dynamic test in ECE RL6, and only high-speed photography will measure the dummy bone. Benefits and chests. 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.

Regarding the test fake person with car collision, there is no unified international standard, and countries use the most use of Hybrid II and Hybrid III, including Europe's Mercedes-Benz Motors, Volkswagen Company, etc. The world's major automobile companies use a large number of Hybrid II and Hybrid III type fake people in automotive collision test research.
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 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. .
