The dynamic vibration absorber consists of a mass and various viscous fluid or viscoelastic materials. These materials possess frequency and temperature dependence of the dynamic properties. Thus it is necessary to take the dependence of dynamic properties into consideration in the analysis or the estimation of the reduction characteristics of the dynamic vibration absorber. There are, however, few papers considering the two types of dependence. In this paper, a new analytical method for the vibration absorber is proposed, which employs the reduced variable method in the field of polymer science and the method of the equivalent coefficient of heat transfer. The method is applied to the Voigt, the Maxwell and the three-element type dynamic absorber previously considered by the author, and as a result, the influence of the ambient temperature and internal heat generation on the reduction characteristics can be examined.
