Title

Techniques in Design and Using VE Dampers

Description

The efficiency of energy dissipation through dampers has been the major concern of damper design. This consideration is based on the assumption that the structure being worked on is proportionally damped. However, most real multi-degree-of-freedom structures are actually non-proportionally damped. For such structures, dampers not only dissipate energy but also transform energy. In this paper, some new dimensions of identifying and using dampers are investigated. A new method of design and re-design of visco-elastic dampers is suggested. Such a method is applicable to many non-proportionally damped systems.

Abstract

The efficiency of energy dissipation through dampers has been the major concern of damper design.

In this paper, some new dimensions of identifying and using dampers are investigated. A new method of design and re-design of visco-elastic dampers is suggested. Such a method is applicable to many non-proportionally damped systems.
