| Resilience often refers to a property of systems,which is described for systems’ capability to recover the state by self-repair after original state degrade from external disturbance.The thesis focused on resilience research of vibration-reduction method to solve the vibration unbalance problem of rectangular thin plate system which is excited by multi-vibration sources.The thesis proposed a resilience assessment framework for vibration-reduction system of rectangular thin plate.The assessment framework is a new analysis concept and method for vibration-reduction system,which considers the failure analysis as well as state recovery.The objective of the research is to propose a resilience assessment framework for vibration-reduction system of rectangular thin plate stimulated by multi-vibration sources,which is aimed at making the vibration state of thin plate in good condition.Firstly,the concept and characteristic of resilience is described.Secondly,a resilience assessment framework for vibration-reduction system of rectangular thin plate is presented.Thirdly,with the purpose of recovering the vibration balance state of rectangular thin plate system,we discussed and validated each part of resilience assessment framework in detailed.The conclusion of the research is that(1)the resilience analysis for vibration-reduction system of rectangular thin plate not only consider recovering the system state,but also consider measuring the recovery strategy quantitatively.(2)The vibration reduction method can be determined by system resilience analysis,which has the advantage of self-repair without external resource.(3)The resilience assessment framework contains four important parts:system identification,failure analysis,recover strategy,metric method,with the proposed framework,the objective of making the vibration state of rectangular thin plate system in good condition is achieved successfully. |
