Experimental study on water-entry of body with buffer at high velocity

In order to study the buffering effect of the structure when it enters the sea at high speed in the air, an effective test method is established in this paper. The experimental method can effectively observe the motion state of the structure body and the deformation process of the buffer structure, and the impact response data collected by the acceleration sensor provides an important reference for the research. The results show that the cushioning device installed on the head of the structure can effectively reduce the overload at the moment of water impact, and the choice of protective material will affect the cushioning energy absorption effect.
