A review of the effect of temperature on the performance of viscoelastic dampers

Abstract

This paper introduces structure and characteristics of viscoelastic damper and analyses the effect of temperature on its performance. Elastic damper is a kind of damping device which mainly relies on the hysteretic energy dissipation characteristic of viscoelastic material to realize the purpose of structural shock absorption. It is widely used in vibration control of mechanical equipment and building structures. However, in the application and research of viscoelastic dampers, it is found that temperature has a significant effect on their performance. This paper first introduces the basic concept of viscoelastic dampers, and points out that there are few papers discussing the effect of temperature on viscoelastic dampers in recent years. In the second part of this paper, the structural composition and characteristics of viscoelastic dampers and viscoelastic materials are introduced. After that, this paper introduces the influence of temperature on the performance of viscoelastic damper from various aspects, and then focuses on the analysis of the influence of temperature on the energy dissipation performance of the damper.
