introduction
The humanoid test device is referred to as "dummy" for short. It refers to a humanoid external form, bionic structure and function, and intelligent response to the external environment.
"Human body double". Dummies are widely used in fields such as medical engineering, safety engineering, environmental engineering and military engineering. They are the national level of science and technology, comprehensive
An important manifestation of national strength. The mechanical damage test dummy can simulate the damage response of a person under mechanical impact load and is directly used for testing and evaluation.
Test equipment for evaluating the safety performance of manned equipment, the protective performance of wearable equipment, the performance of weapons and equipment and other equipment performance related to personnel injury.
It is the core technology that supports the research and development of manned equipment and various types of equipment. Developed countries such as Europe and the United States had already begun to do so as early as the 1940s.
Research on dummies for mechanical damage testing. After long-term development, dummy products for mechanical damage testing have been serialized, and their types cover
It covers various groups such as men, women, children, infants, pregnant women, etc., and its uses include various forms of car crash tests, train crash tests, military
Equipment protection performance testing, aerospace equipment protection performance testing and other fields.
Currently, the dummies used in China are designed based on European and American human body dimensions and mechanical properties. Based on the collision test method widely used in various fields in our country
Take the trial dummy as an example. This dummy was developed based on the 50th percentile human body size in the United States. The body shape difference is relatively different from that of the 50th percentile human body in China.
Large; related research shows that in automobile crash tests, the damage response of Chinese human-sized dummies is consistent with the existing collision response based on European and American human-sized dummies.
There were also significant differences in the damage response of the test dummies. Therefore, the existing crash test dummies based on European and American human body dimensions are directly used for automobile testing.
Vehicle safety testing and evaluation will lead to the inability of the occupant restraint system to effectively protect the Chinese human body. In addition, due to the lack of corresponding experiments
Basic research on dummies, lack of testing and evaluation standards for dummies that conform to Chinese human body characteristics, in my country's military industry, aerospace, rail transit and other fields
In the safety test of manned equipment, only crash test dummies based on European and American human body sizes in the field of automobile collision can be generally used, which makes
The development of manned equipment safety protection technology in related fields has also been greatly restricted.
This document gives the design principles to be followed when designing a dummy for mechanical damage testing, the relevant human body characteristics that are key considerations, and the dummy's
The test method for biomechanical performance calibration is designed to develop specialized testing methods for various complex application conditions in the fields of automobiles, military industry, aerospace, rail transit and other fields.
A mechanical damage test dummy is used to provide forward design standard support.

The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, the dated quotations
For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to
this document.
GB/T 5703-2023 Anthropometric basic items for technical design (ISO 7250-1.2017, MOD)
GB/T 10000 Adult human body dimensions
3 Terms and definitions
The terms and definitions defined in GB/T 5703-2023 and the following apply to this document.
3.1
dummy
Humanoid test device for mechanical damage testing.
Note. A complete dummy consists of multiple parts assemblies that reflect various parts of the human body.
3.2
percentilepercentile
The normal distribution statistical proportion obtained from the census of human physiological data (height, weight).
Note. The 5th percentile (5th), the 50th percentile (50th), and the 95th percentile (95th) are commonly used human body percentiles. For example, the 5th percentile of height
Adult men means that 5% of individuals in the male population have a height parameter less than or equal to this value.
3.3
human-bodysegment
The human body is divided into several segments based on bony landmarks.
3.4
The local coordinate system of each human body segment is usually used to provide a fixed reference for the position of the center of mass on each body segment.
3.5
Human body segment center of mass position positionofmasscenter
The position of the center of mass of a human body segment relative to the origin of the coordinate system of the body segment.
