Paper Abstract

Aim of research: Human body segment inertial parameters are the basic physical quantities in the study of human body in motion. Through careful calculation, inertial parameters such as the position of center of mass and moment of inertia of the total and segmental human body in motion in random postures have been obtained. Research method: Based upon the basic inertial parameters derived from Hanavan human body model and from Barter regression equation, upon position vector, moment and moment of inertia of the human body and segment relative to inertial reference frame by means of transformation matrix, and upon the resultant moment theorem and the parallel-axis theorem, inertial parameters such as the position of center of mass and moment of inertia of human body in random posture in motion are thus obtained. Result and conclusion: The research findings are in accordance with those of the balance plate and trilinear pendulum. The characteristics of individual and random posture of human body inertial parameter in motion are presented in this paper.
