Abstract
This paper deals with the design method of a thin plate structure with a fixed end and a contact area in consideration of the contact state under vibration. The boundary condition of a cantilever beam with a contact area depends on the contact force at a contact area. Therefore, it is necessary to consider the vibration characteristic with a contact condition in the case that the beam is designed. In the previous study, the authors proposed the finite element model of the beam with a contact area which is described as two-dimensional beam element. However, the detailed model of a contact area is needed for estimation of response of the beam under vibration. In this study, the simple design method of beam with a contact condition is investigated. Firstly, the finite element model of the beam with a contact area which is described as non-linear spring element based on Hertz theory of elastic contact. Secondly, the comparison of the response between the result of numerical simulation using the FE model of the beam and vibration test is shown. The numerical simulation using the FE model can be useful for obtaining contact condition without vibration test.
