Embodiment 1

[0033] combine Figure 1 to Figure 5 , the present invention builds a model test device for simulating a structure hitting ice on the base plate 1, including an ice tank 2, an ice tank end cover 3, a rubber block 4, a hydraulic rod 5, a sliding support 10, a fixed support 11, etc. The components are composed of two sets of fixed supports 11 and one set of sliding supports 10 at corresponding positions according to the length and thickness of the ice tank. The supports are used to support the ice tank and are welded to the bottom plate; It is to open an opening through the middle of a rectangular box according to a certain size. The four long sides of the box are designed to be cylindrical, and the radius of the cylinder is the same as the radius of the support. When the tank stores water and makes ice, the ice tank is closed. The end cover of the ice tank is provided with a threaded hole at the same position as the ice tank and is connected by a bolt 7. The inside of the end c...

Abstract

The invention belongs to the technical field of model tests, and particularly relates to an engineering structure ice-collision transverse ice load loading device and method. Through the arrangement of the ice tank, the lifting system and the model power system, the actual condition when a structure collides ice can be well simulated, and when the ice tank is in a horizontal state, water injection ice making is performed layer by layer, so that air holes can be prevented from occurring in an ice layer; considering the real condition of collision between a structure and ice, two ends of the ice groove need to be opened, so that when the model collides to the ice surface at a certain speed, the ice surface at the other end has no constraint; different speeds are provided for the test model through the flat car, the flat car is provided with the adjustable clamp used for fixing the model, model tests of different scales can be provided, the real collision condition of a structure and ice can be well simulated, the structure is simple, cost is saved, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of model tests, and in particular relates to a lateral ice load loading device and method for an engineering structure hitting ice. Background technique [0002] In sea areas with high latitude, ice floes on the sea in winter will collide with large marine engineering structures, such as offshore platforms and polar ships, under the action of wind, waves and currents. The collision between ice and large structures will cause irreversible damage to these structures. damage, resulting in reduced safety. The research on ice breaking of engineering structures is still in its infancy, most of which are based on numerical simulations, and few studies on model tests. Therefore, it is very necessary to conduct experimental research on engineering structures impacted by ice. Contents of the invention [0003] The object of the present invention is to provide a lateral ice load loading device and method for an eng...
