This paper presents a new approach to analysis forced vibration response of multi-degree-freedom system which consists of some mass and springs. Many authors analyzed fatted vibration response with issue of eigenvalue and direct numeric-al integration, but these methods are complex to solve, and difficult to grasp vibration. We analyze forced vibration response with vibration transmissibility. It is possible to describe easily resonance curve in any parameter of multi-degree-freedom system It takes the form of the fraction. The root of the denominator shows the resonance point, and root al the molecule shows the anti-resonance point. We experimented in order to verify this method. And we compared calculation curve with experimental values. We find that the tendency which is identical for both was obtained. The result shows that out analysis method can disc be vibration of multi degree-of-freedom system.
