Description
Technical Field
The invention belongs to the technical field of liquid storage devices, relates to a liquid storage tank with a double-layer cylindrical grid and a stress calculation method thereof, and particularly relates to a liquid storage tank capable of achieving an effect of inhibiting sloshing liquid by means of good energy dissipation performance of the double-layer cylindrical grid, namely by means of sloshing energy dissipated in a liquid tank through holes.
Background
In the engineering fields of aerospace, hydraulic engineering aqueduct structures, large ocean vessels transportation, ultra-large crude oil storage tanks and the like, liquid sloshing is a ubiquitous phenomenon and affects the design of engineering structures and the safety of engineering operation. The tank body is characterized by large reserve, and when the external excitation frequency is close to the natural frequency of the container, liquid sloshing can generate resonance, and large oscillation occurs. The intense liquid oscillations will create a significant hydrodynamic pressure on the container walls, compromising the container. For example, for marine vehicles such as ships, ships and vessels, the damage of the tank body can cause oil leakage to pollute the sea, and the capsizing of the ships is a great loss of life and property safety of people; for civil enterprises such as oil houses and nuclear power stations, the enterprises are often close to cities, once the tank body is damaged, secondary accidents are very easy to occur, serious losses are caused to lives and properties of people, the ecological environment of the cities is damaged, and the consequences are not considered.
The mechanism of the liquid storage tank sloshing is mastered, reasonable liquid tank design is carried out in a targeted manner, the liquid storage container structure is optimized, the liquid tank sloshing amplitude and the impact pressure are reduced, and the possibility of accident occurrence is the current research hot spot and key point. The design of the damping structure in the tank is a convenient and quick method, and the damping baffle plate is used for the simplest structure, however, the baffle plate type and the relative position of the baffle plate in the container have great difference in the anti-shake effect. Different types of baffle anti-sloshing mechanisms become the key to reasonably design the tank. Aiming at a cylindrical liquid storage tank, the existing research and design achievements are mostly limited to a single or a plurality of annular horizontal solid baffles (fixed on the side wall of a container), but the research on vertical baffles coaxial with the cylindrical liquid storage tank is not yet reported, and if the baffles are arranged, the container is easily divided into a plurality of independent water tanks, but the shaking reduction effect is not realized. The good wave eliminating performance of the perforated plate breakwater in the coast engineering field is combined, the perforated grid is transplanted to the cylindrical liquid tank, so that the fluid can be effectively inhibited from climbing on the side wall of the liquid tank greatly, the sloshing energy in the liquid tank is dissipated by virtue of the pores, and meanwhile, the huge impact force suffered by the tank body can be greatly reduced.
