Content
The Simplest Anelastic Model (SAM) is used frequently to describe vibration response of a moving mass mounted on viscoelastic isolators. It does increase by a relative small constant amount with frequency and posses a transition frequency, even though it is suggested that the properties of the SAM are not representative of the mechanical properties of rubber materials. The purpose of this paper is to explore the characteristics of the SAM when the Williams-Landel-Ferry (WLF) equation is used to transfer the dynamic properties of rubber material from one temperature to another. It is found that the predicted transmissibilities at different temperatures intersect to a single point. This paper will show the characteristics of the intersection point. It will show that the simulation is not accurate if the measured transmissibilities at different temperatures do not pass through the intersection point.
