The Crash Test Dummy is a kind of test equipment with a special structure made of a variety of special materials according to the principle of ergonomics. The most important requirement of the Crash Test Dummy is to be able to simulate the injury of the human body in the process of automobile collision as realistically as possible, and to install various types of sensors to facilitate the collection of various signals during the collision process. In addition, the Crash Test Dummy needs to be able to meet the requirements of repeated use.
The Crash Test Dummy was developed in the 1960s. After more than 50 years of development, various types of Crash Test Dummy have been produced. Crash Test Dummy are mainly divided into adult dummies and child dummies in terms of body size; according to the type of collision, they are divided into frontal impact test dummies and side impact test dummies.
The price of Crash Test Dummy for automobiles is very expensive. One Hybrid III 50th male dummy (the size of the human body is basically normal distribution, 50th refers to the body size of the dummy can cover 50% of the overall male human body size) is equivalent to more than 100 units The top-of-the-line iPhone 7 is priced at more than 8,000 yuan. The high price is mainly due to the high research and development cost of the dummy, many parts, and the need to carry various test sensors. Taking Word-SID as an example, the dummy reserves up to 200 sensor channels. The price of the sensor and the corresponding acquisition system and processing software are expensive. Most importantly, the dummies used in car crashes are basically an international monopoly. Therefore, under the influence of various factors, the price of automobile Crash Test Dummy remains high.
