In this report, the authors propose a new method for structural dynamic modification. The resonance sensitivity and anti-resonance sensitivity of a structure are used in the proposed method. Both sensitivities can be calculated much more easily than the sensitivity for the natural modes because of the simplicity of the calculational procedure. Therefore, this method has a high degree of efficiency. The target peaks of resonance are removed by making the vibration node coincide with an exciting point. As a result, cancel of the resonance peaks is achieved. In this paper, the theory of the proposed method is explained at first. Secondly, the effectiveness of this method is concretely shown with two applications : a 6-degrees-of-freedom system and a rectangular plate. In the latter application, an experiment is also performed in order to verify the effectiveness and accuracy of the method.
