| Outline of Final Research Achievements |
This study aimed to establish a general framework for the wave analysis and control of intricately connected damped mass-spring systems, and discussed the analysis and design method focusing on the global periodic properties of the structures (first order recurrence formula expression in the Laplace transformation domain). As a natural extension of the previous results for the simple cascade-connected damped mass-spring systems, we especially considered: damped mass-spring systems whose connections are beyond adjacent masses; damped mass-spring systems whose masses have two dimensional connections (in the longitudinal and lateral directions); and general mono-coupled periodic systems whose internal structure of the subsystem is not specified explicitly. For the above systems, we discussed the analysis and design method for the wave analysis and control by utilizing the above periodic properties of the systems.
