Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
The principle of Main Basis of the present invention is: carry out numerical simulation to the shock environment of above water craft under the effect of shock load, the shock response spectrum obtained after reprocessing can show that the vertical maximum spectrum speed being positioned at same examination position is greater than its laterally maximum spectrum speed, illustrate that above water craft is when being subject to impacting, the more horizontal shock response of vertical shock response is more strong, and the shock response that therefore boats and ships are bearing the Ship Structure under the effect of underwater shock load is mainly vertical response.Transverse response relative with vertical response vertical negligible, but for Submarine Structure, shock response is different from above water craft.Therefore the platform of similar submarine external structure is adopted can to reach good effect.
The technical solution adopted in the present invention is: based on above principle, impact main platform body of the present invention is established and is comprised cylindrical housings 10 and square casing waterborne 9 under water, due to the floating shock platform of design, because the above structure of Water Plane must be had, therefore equal diameter cylindrical shell upper end is clipped as cylindrical housings 10 under water by the present invention, and cylindrical housings 10 upper end arranges corresponding direction housing as above water under water, form the shock environment that class submarine bay section better simulates submarine, load line ensures cylindrical housings 10 and square casing waterborne 9 centre under water.And square casing waterborne has large opening, can ensure that testing apparatus is more easily laid, also can ensure the impact strength of platform above water structure.
