Introduction to common car test dummy parametersRelease time: 2015-09-12 08:44
Automobile test dummy has an important role in the safety of cars. The safety of getting out of cars is being paid more and more attention. Because of the frequent occurrence of automobile safety accidents, research on the safety performance of enterprises is a major issue facing many manufacturing enterprises. The subject of the car test dummy can most realistically simulate the scene of a car accident. The engineer of Standard Group (Hong Kong) Co., Ltd. will briefly introduce the development history and parameters of the car test dummy for you.
A small history of dummy models used in crash tests:
In 1948, the U.S. Air Force first used human models for aircraft seat ejection tests;
In 1950, automakers began developing mannequins for crash tests;
In 1973, General Motors developed a better humanoid model, Hydroid2;
Hydros3 and US SID in the 1980s;
In 1991, Europe launched its own side impact model EURO SID.
Most of the mannequins are made of metal and plastic. The chest cavity is made of steel, the scapula is made of aluminum, and the pelvis is plastic. A mannequin is worth 150,000 to 300,000 marks. The mannequin has about 60 sensors. .
Three human models for car collisions:
1.50% mannequin: representing a medium body with a height of 177 cm and a weight of 86 kg;
2.95% mannequin: a large figure representing a height of 188 cm and a weight of 108 kg;
3.5% mannequin: a short figure representing a height of 148 cm and a weight of 56 kg.
At the NACP European Safety Impact Testing Center, Hy-drid3 is used to collect frontal crash information for child mannequins:
1.6-month human model: 67 cm tall and 10 kg in weight;
2.December human model: height 76 cm, weight 13 kg;
3.18 months human model: 83 cm tall and 16 kg in weight;
4.3-year-old model: 97 cm tall and 20 kg weight;
5.6-year-old model: 130 cm tall and 30 kg in weight;
6.10-year-old model: 138 cm tall and 36 kg in weight.
