A Biomechanical Computerized Simulation of Human Strength

Abstract

A computer based three dimensional strength model was used to predict hand forces at 38 different positions for a seated operator. These predictions were compared with the forces exerted by 71 male subjects. Error coefficients of variation averaged from 0.27 to 0.49, and correlation coefficients between the measured and predicted hand forces averaged from 0.93 to 0.97. The hip height predictions proved more accurate than the shoulder height predictions.
