【 摘 要 】

The acting force mechanism of the water layer of the cavity on a body when it crosses the water surface is studied. A simplified mechanical model is proposed to explain the mechanism of the impact of the water layer onto the body. The estimating formula for the maximum pressure in the water layer and on the body surface impacted by the water layer is derived. It is proved that the maximum pressure is always in proportion to the square of the moving velocity of the maximum pressure position.
