A brief introduction of National Standard of the People's Republic of China "Mass Center of Chinese Adults"

This standard applies the CT (computerized tomography) method to measure the inertia parameters of Chinese adults. Male and female Chinese adults were chosen as samples to take computerized tomograms from, and 82 items of body-shape indexes were measured. The densities of 19 kinds of tissues and organs were also measured, and 16 items of human body segment parameters were obtained. In addition, the regression equations for the calculation of the inertia parameters of the human body were set up. Based on the data in the Database of Chinese Adults, the National Standard GB/T 17254-1988 ("Mass Center of Chinese Adults") has been prepared. Rubber dummies have been made in order to perform simulation experiments of human body movements. A new type of helmet was developed to improve the stress conditions of the neck, and a rational, simplified model of Chinese youths has been made. These achievements can be widely used in national defense, industry, sports, and many other fields.
