ISSUES IN REDUCED ORDER MODELING OF MECHANICAL SYSTEMS
Abstract eng: This study investigates the possibilities of obtaining reduced order mass-damping-stiffness models of mechanical systems via identified state space realizations. Initially the full order problem is reviewed and conditions regarding the number of sensors/actuators are developed. These investigations are then extended to test setups in which one has an insufficient number of instrumentation on the system, and some methods of obtaining reduced order models are discussed. Effects of commonly used idealizations such as classical damping and diagonal mass matrix are also explored in developing alternate formulations.
