Integration Method of CAD Systems

Abstract

This paper presents the modification of a non-iterative algorithm for the component-oriented simulation of the dynamics of multibodies. Now the method can be implemented for the component-oriented simulation of the dynamics of CAD systems with redundant constraints. Also the new version of the method is well-suitable for the implementation of sparse solvers. The algorithm was implemented in the Virtual System Designer (VSD) software, integrated with a CAD tool Autodesk Inventor. The simulation results of two CAD models: a car and a steam machine shows the method's stability and accuracy.
