Paper Abstract

Substructure synthesis is an efficient modeling tool for complex vibration isolation systems. The advantages that are demonstrated include the ability to adapt to design changes, and include additional kinematic constraints into the model formulation. In general the advantages of substructure synthesis are that only admissible functions are needed to model the structure and a reduced number of degrees-of-freedom can be used in comparison with other methods such as the more standard finite element method. The problem formulation has a composition similar to the physical construction of actual systems. This enhances the practical understanding of the system modeled. The contribution here is to demonstrate a substructure synthesis method and its application to model complex kinematic constraints for a vibration isolation system.
