A NOVEL EXPERIMENTAL MODAL ANALYSIS METHOD BASED ON RESPONSE CONTROL APPROACH FOR NONLINEAR ENGINEERING STRUCTURES

摘要

The invention is related to the field and methodologies of "nonlinear system identification in structural dynamics". In other words, it is related to the field and methodologies of constructing a mathematical model describing the vibration behaviour of a nonlinear system using experimental data. Moreover, the invention can also be used for systems in which nonlinear properties can be neglected.
