A new type of interlayer marine structure and its hydroelastic analysis method

Abstract

The invention provides a novel sandwich type marine structure and a hydroelastic analysis method thereof, which belong to the field of marine structure design and parameter calculation. The new sandwich type marine structure includes upper and lower panels and a core material, the core material is located between the upper and lower panels, and the core material and the upper and lower panels are fixed as one; the continuity condition is used to establish a group of equations, combining different Determine the expansion coefficient of the velocity potential, quickly and effectively obtain the reflection coefficient and transmission coefficient of the sandwich super-large floating body, as well as the deflection, bending moment and shear force of the lateral vibration of the sandwich-type super-large floating body; The inventive method can quickly obtain the hydroelastic dynamic response of the marine structure, and provides scientific guidance 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. [0003] In the basic hydroelastic theoretical analysis of super-large floating b...

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
