Abstract	One of the most critical issues for fusion in-vessel components is to reduce the transient electromagnetic force due to plasma disruption and to establish suitable support structures. It is indicated that the component deflection is damped by the secondary induced eddy current to reduce the primary electromagnetic force (coupling effects of electromagnetic induction and mechanical deflection). In order to perform the structural design of components, we must fully understand the transient electromagnetic phenomena. For the better fusion reactor design, we've developed a computer code for 3-D thin shell structure with non-ferrous and elastic conductors. Here, we employed a finite element numerical model for mechanical deformation and a wire-grid numerical model for eddy currents. In order to verify the computer code and to understand the influence of support condition in consideration of above coupling effects, we performed some experimental and numerical studies. The experimental results agree well with the numerical results, and we could grasp the influence of support condition for the vibration phenomena in the magnetic field.
