Interactive Computerized Symbolic Dynamics for the Dynamicist

This paper contains a discussion of a new methodology for employing, on a desktop computer, computerized symbol manipulation for formulating explicit equations of motion and writing complete FORTRAN simulation programs for multibody systems. The approach is based on Kane's dynamical equations and its underlying concept is to use the computer to mimic the step-by-step process a human analyst undertakes while formulating equations of motion and writing FORTRAN simulation programs by hand. Implementation of the methodology is illustrated by means of examples.
