To investigate the dynamic characteristics of the elastomers, a series of Hopkinson's bar experiments were performed. From the experiment results it was found that with different ratios of length, diameter(L/D) and different hardness, an elastomer exhibits different cut-off and nature frequency characteristics. A mathematical model of the frequency response function for cylindrical elastomeric specimens has been developed. This model can be used as the basis for a computer-based... To investigate the dynamic characteristics of the elastomers, a series of Hopkinson's bar experiments were performed. From the experiment results it was found that with different ratios of length, diameter(L/D) and different hardness, an elastomer exhibits different cut-off and nature frequency characteristics. A mathematical model of the frequency response function for cylindrical elastomeric specimens has been developed. This model can be used as the basis for a computer-based routine which is able to simulate frequency response characteristics i.e. filtering ability of given size and hardness of elastomeric specimen. The simulation results agree with the experiment results which indicate that the elastomer with this dynamic characteristics can be utilized as mechanical filter. |
