Abstract
The boundary conditions of a thin plate are identified by using an approach linking dynamic response measurement and boundary element analysis. Under known dynamic excitation, according to the measured vibration response at certain points on the plate, the stiffness parameters at the boundary supports can be well estimated. An approximate fundamental solution technique has been adopted in establishing the boundary integral equation for the dynamic problem of a thin plate. By simulation examples, the feasibility and effectiveness of the method offered are fully demonstrated. The accuracy of the identified results is sufficiently satisfactory for engineering problems.
