In this study, we applied an impact mass damper to a scale model of C-frame turret punch presses and investigated the effect of reduction of vibration and noise. The influence of the contacting conditions between the damper and the frame on the damping characteristics is basically analyzed by the finite-element method. From the simulation, it is found that the apparent spring constants can be changed by adjusting the contacting force of the impact mass damper with the main frame. Moreover, the experiments were conducted in order to reduce the vibration and noise by using the impact mass damper. As a result, the amplitude of the tuning vibration mode, that is the first resonant vibration mode of C-shape structures can be reduced to up to 10% of the original model without any damper, and the noise level can be also reduced by over 6 dB.
