Multi-Rigid-Body System Dynamics with Applications to Human-Body Models and Finite-Segment Cable Models.

Abstract

A computer-oriented method for obtaining dynamical equations of motion for large mechanical systems or chain systems is presented. A chain system is defined as an arbitrarily assembled set of rigid bodies such that adjoining bodies have at least one common point and such that closed loops are not formed. The equations of motion are developed through the use of Lagrange's form of d'Alembert's principle. The method is illustrated and applied with human-body models and finite-segment cable models. The human-body models are configured to simulate a crash-victim. Results with several applied deceleration profiles agree very well with available experimental data. The cable model is configured to simulate an off-shore oil rig or ship's crane with a partially submerged towing cable. (Author)
