The research and application of human inertial parameters is an important basic research topic in the field of human ergonomics related to human body measurement biomechanics. Human inertial parameters include: the mass of the whole human body and each body segment, the position of the center of mass and its moment of inertia. They are the basic parameters for the study of human movement and sports injury simulation and prevention, and are also an important part of ergonomics, anthropology and human science research, with important academic value and practical background. The application field of human inertia parameters is very wide. For example, in the analysis of human motion videos, gymnastics, skills, diving and other action designs: fighter ejection seat design: spacecraft special dummy design and astronaut motion analysis: safety design: factory buildings and manned equipment expansion fence design, etc., this parameter is needed. This standard is compiled on the basis of the National Standard for the Center of Mass of the Adult Human Body and further verifies the corresponding technical achievements. It is more enriched, improved and convenient for promotion and use in various fields, creating conditions for the rapid transformation of scientific research results into productivity, and laying a foundation for the development of the national economy and social progress. 1 Scope
