Abstract
The body center of mass (COM) plays a prominent role in occupational ergonomics. By analyzing the body dimension parameters, anthropometric inertia parameters, i.e. mass, COM location and inertia, can be determined. The parameters can then be applied in diverse areas such as developing an artificial limb for the physically disabled, designing protective appliances and wear for laborers, designing an ejection seat for a fighter jet and performing motion analysis of astronauts. This study measures 15 kinds of basic segment parameters in the human body for Chinese adults. Computer tomography and image processing are adopted in the measurements. Based on the body dimension parameters, a mathematical model is also derived/presented to estimate the segment mass and segment COM of Chinese adults. The data accuracy is quite remarkable. Relevance to industry The results obtained in this study can be applied to the designs of safe protection devices and appliances in the workplace, and the development of artificial limbs for osteological and rehabilitation medicine.
