Determination of the Mass Properties of a Human in Any Position

Abstract

In the past, human body models have been developed by assuming simple geometric shapes for the components of the human. body in order to predict the mass properties, i.e. mass, center of mass, and inertia tensor. In this study a new personalized method of predicting component mass properties is developed based on experimental data for whole-body mass properties for three body positions where only one component is moved. Also needed, however, are estimates for the mass and sum of the moments of inertia of each component. Additionally, the contribution of outer garments or a suit to the mass properties can be included in the prediction if it is assumed that the components of the outer covering are rigid bodies that move negligibly relative to corresponding body components.
