Abstract:  The dynamic characteristics and the temperature effects on a kind of cylindrical
shear viscoelastic damping members are experimentally studied in this paper. Then, the experimental analysis of dynamics of the space truss damped with the developed viscoelastic members is carried out with environment temperature varied. The obtained experiment results indicate that, it is very efficient to suppress the vibration response of the structures with original members substituted by damping members, and the dynamic characteristics of the space truss is highly influenced by environment temperature due to the integrated viscoelastic damping members which are sensitive to temperature.
Keywords: viscoelastic, damping member, temperature characteristics, truss structure.
