Abstract
This paper shows new method to describe forced vibration response of multi-degree-of-freedom system. This method is possible to obtain transmissibility of vibration by manipulating equation of motion without the issue of eigenvalue. The transmissibility we obtained can describe resonance curve in any parameter of multi-degree-of-freedom system. It takes the form of the fraction. The root of the denominator shows the resonance point and root of the molecule shows the anti-resonance point. It is not considered that it's property to depend on temperature, distortion and frequency. 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 of comparison shows that there is validity in this method.
