The novel sandwich type maritime work structure comprises an upper panel, a lower panel and a core material, the core material is located between the upper panel and the lower panel, and the core material, the upper panel and the lower panel are fixed into a whole; an equation set is established by utilizing a continuity condition, an expansion coefficient of a speed potential is determined bycombining end conditions of the interlayer type super-large floating body in different states, and a reflection coefficient and a transmission coefficient of the interlayer type super-large floating body and deflection, bending moment and shearing force of transverse vibration of the interlayer type super-large floating body are quickly and effectively obtained; according to the method, the hydroelastic dynamic response of the maritime work structure can be rapidly obtained, and scientific guidance is provided for actual engineering construction design and parameter optimization.

Description

technical field [0001] The invention belongs to the field of marine structure design and parameter calculation, and relates to a novel interlayer marine structure and a hydroelastic analysis method thereof. Background technique [0002] Super-large floating bodies have important application value in civil / military fields such as marine resource development, marine tourism, and island and reef garrison. The sandwich structure can withstand large bending loads with low self-weight, and has good stability under in-plane loads, which is easy to implement Smooth and flat hydrodynamic surface; ultra-high performance concrete (UHPC) has the physical characteristics of light weight, high strength and durability, and the implementation of opening design further improves the specific stiffness of the material, and its application in the sandwich structure can make it better in load bearing and stability.

Problems solved by technology

In the traditional hydrodynamic analysis of elastic plates, the structure is regarded as a homogeneous Euler-Bernoulli plate / beam, but for the hydroelastic analysis of sandwich-type ultra-large floating body, since the transverse (bending) vibration equation of the sandwich structure is relatively different from the traditional The single-layer structure is more complicated, and the traditional hydroelastic analysis method is difficult to apply
