発泡樹脂材料の振動減衰特性評価とモデル化手法に関する研究

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 using the experimental result. These results show that it is important to take the effect of the expansion ratio on the material damping into consideration.
