The Research on the Damping of Prestressed Membrane Structure Subjected to the Impact Load

The damping ratio plays a main role in the vibration of membrane structures. In order to study force air application structures, this present paper investigated response structure subjected impact loads. Eight experiments with different tension forces were conducted, and load was simulated using rigid bullet certain velocity. displacement data obtained laser meter. FEM used simulate vibration, results had good agreement. show that effect applied prestressed equivalent viscous damping, determined air. proportional density over membrane. parameter coefficient could be geometry structure.
