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.

为了研究汽车轮胎源和橡胶球源之间的关系，对汽车轮胎源和橡胶球源的冲击力特性、地板冲击压力水平和位移t进行了测量。结果表明，跌落高度的对数与冲击暴露水平呈高度线性关系。然而，当橡胶球源从140或150 cm的高度落下时，不存在线性。同时，得到了冲击过程中的动态弹簧常数.
