In a definite scope, the impact time and contact area are linearly increased while the maximum acceleration and bruise volume reduced with the increment of thickness of cushion materials.
在一定范围内，随着缓冲材料厚度的增加，碰撞时间与接触面积线性增加，最大加速度与损伤体积相应减小。

The main design problems of air cushion surge shaft include designing norm, layout design, water curtain design, the estimation of gas volume a.
After that, the volume of the inflated cushion is measured and the size of the object of interest (100) is derived from the volume of the inflated cushion (104).
