OS0708 Identification of damping capacity of foamed plastics

Abstract

Damping properties of foamed plastics is analyzed experimentally using an impulse technique. To investigate the influence of expansion ratio on vibration damping characteristics, vibration tests are implemented. The damping capacities of foamed plastics are identified by the experimental result. These results show that it is important to take the effect of the expans km ratio on the material damping into consideration.
