Abstract

The invention discloses a diving slamming experimentation device for an ocean structure. The diving slamming experimentation device for the ocean structure comprises the structure, a power system, a load rejection system, a control and measurement system, a buffer system and a substrate, the power system mainly comprises a motor seat, a screw rod, a vertical lead rail, an optical axis and a screw rod; the load rejection system comprises a primary load rejection carriage, a secondary load rejection carriage, an electromagnet and a slide block; the control and measurement system mainly comprises a computer, a data gatherer, a constant-voltage direct current power supply, and an upper and a lower limit switch, the buffer system comprises a buffer substrate, a spring bumper and a buffer platform, the control and measurement system controls through motor motion and magnetic force of the electromagnet to realize primary load rejection and secondary load rejection, the structure falls into the water, and a pressure sensor arranged on the structure returns the measured data to the computer through the data gatherer. The diving slamming experimentation device for the ocean structure is simple in structure, convenient to operate, stable in move and suitable for the diving slamming experiments for different types of ocean structures.

Description

technical field [0001] The invention relates to the field of ship and marine engineering experiments, in particular to a device for slamming a marine structure into water. Background technique [0002] The water landing of seaplanes and spaceships, the water impact of air-dropped torpedoes, the slamming of ships in wind and waves, and the throwing of lifeboats at sea will arouse the movement of the surrounding fluid medium; in turn, the fluid medium exerts pressure on the structure Various reaction forces, especially in the initial transient period (milliseconds) of the impact of entering the water, will suffer a huge impact load. This involves the dynamics of structural man-water impact. The research on the human-water problem plays an important role in the design of the strength of the water-entry structure: for example, in the process of air-dropped or rocket-assisted underwater weapons invading from the air medium to the fluid medium, they are faced with structural damag...
