Boundary Condition Identification of a Clamped Beam in the Flexible Support

Mechanical structures usually contain joints or boundary conditions which affect their dynamic characteristics. Dynamic modeling of mechanical structures depends upon precise modeling of joints or boundary conditions. In this paper identification of boundary conditions of a clamped beam in flexible (non-rigid) support is considered. An identification approach for support parameters is introduced based on using natural frequencies. Simulated and experimental case studies are used to show the applicability of the introduced model. The results show the accuracy of the proposed method.
