This paper presents a method for the suppression of large amplitude bending vibrations of a clamped curved beam by controllable forces in an elastic support. The elastic support force, acting on the middle span of the beam, is generated by the electromagnet. Applying the Galerkin method to the basic equations, non-linear coupled differential equations are reduced: the forced responses are calculated utilizing the harmonic balance method. From the analytical results, it is shown that natural frequencies are easily shifted away from the resonant frequency by the changeable support forces. Experimental work has also been carried out to clarify the validity of this control method. It is found that the experimental results are good agreement with the analytical ones.
