A Sparsity-Oriented Approach to the Design of Mechanical Systems.

Abstract

In this paper, the systematic formulation of the equations of motion for three-dimensional mechanical systems (mechanisms) is considered in view of sparsity requirements for large simulation problems. Topological approaches of previous authors are extended to include the practical case of joint-constraints, and the resultant formulation is also related to Lagrange multiplier methods. Finally, a simulation example of a three-dimensional landing system model is studied several times larger than heretofore state-of-the-art problems and the growth rate of computation time with problem size is noted.
