| Research Abstract |
The analytical model including nonlinearity of system enables to confirm the behavior of system after occurrence of polygonal pattern formation phenomena. This result has been verified experimentally and correspondence of soft spring behavior and jumping phenomena of amplitude response has been confirmed. Additionally, our developed stability analysis has been modified to be available to analyze stabilities of systems including different delay times and the validity has been confirmed by comparing to results of conventional method.
