BIOMECHANICAL CONSIDERATIONS OF PULLING FORCE IN TUG OF WAR WITH COMPUTER SIMULATION

Abstract

The purpose of this study was to investigate pulling force in tug of war in accordance with the changes of the tuggers’ posture using the computer simulation, and considering the characteristics of human body such as body height, body weight, and holding height. As the model of human body, a 3-segmented rigid multibody system was made, which had three movable joints. After modeling, the validity of the model was verified by experimental data. As a result, pulling force was proved to be changed by the posture of the tugger, and increased by 2.8kg per 1 degree decrease in body inclination. Finally, it was found out that the maximum pulling force could be exerted in a certain posture of the tugger.
