| Research Abstract |
The impact force characteristic, the floor impact pressure level and the displacement t of the heavy/soft impact sources were measured, in order to investigate the relation between the car-tire source and the rubber ball source. As results, it could be seen that the logarithm of drop height and the impact exposure level had a high linear relationship. However, when the rubber ball source was dropped from the height of 140 or 150 cm, there was no linearity. Moreover, the dynamic spring constant in the impact time was obtained.
