This paper studies to find another analysis way of forced vibration response without the issue of eigenvalue. This way is a method to solve equations of motion in each mass as simultaneous equations. Only in the system composed of spring and mass before, this method was able to adapt However, this method would be able to adapt in the system which attenuated. The method salves a close solution of three and four-degree-of-freedom-systems consist of mass and viscoelasticity element. It is not considered that it's property to depend m temperature, amplitude and frequency. We experimented it 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 results show good agreement with calculated ones.
