Abstract

This paper presents the experimental approaches on the shock absorbing effect of rubber-cushion by impact tests. First, the static compression test was performed to compare the filled rubber with the hollow rubber. Second, the preliminary impact test was carried out in order to examine the effect of rubber-cushion depth. It is found that the rubber-cushion depth has no influence on the maximum impact load within the preliminary impact test. Finally, the model impact test was executed in order to investigate the effect of impact speed for the rubber-cushion. It is confirmed that the rubber-cushion can reduce about 40-50% of impact load for the velocity of more than 5m/sec.
