Hanging type test platform

Abstract

The invention relates to the technical field of ship and ocean engineering underwater test devices, in particular to a hanging type test platform. The test platform can realize simulated butt joint rescue and material transfer of a lifesaving bell, a lifesaving submersible vehicle, a deep diving lifeboat and a submarine, can also realize butt joint of a shuttle submersible vehicle and a deep sea space station, realizes material transfer simulation, can carry out novel equipment development, test and test, and can carry out various trainings at the same time. By arranging the lifting device, different water depth environments can be simulated, and divers can simulate and train overwater and underwater operations under different sea conditions. Based on the irregular wave superposition theory, the characteristics of electric actuation and frequency modulation of a high-elastic dielectric material are adopted, waves are accurately simulated, a wave maker is not needed, and the cost is saved.

Problems solved by technology

[0002] Most of the current docking and transfer drills and training for submarine rescue and rescue are carried out at sea. The drills and training are greatly affected by factors such as seasons and sea conditions, and the pre-preparation period is long. , and it is difficult to achieve high-frequency training and testing, and there is a lack of relevant test simulation platforms in the prior art for simulation devices for personnel to exercise in water

Shanghai Jiao Tong University proposes a kind of ship motion simulation device in CN1491852A, and simulates motions such as ship rolling, pitching, heave by arranging hydraulic oil cylinder on the simulation platform; A similar ship simulation platform is proposed, but the above structure cannot be applied to underwater submersibles, diving bells and other structures, and cannot simulate deep water operating environments

In addition, the above-mentioned structure relies on the simulation of the degree of freedom of the mechanical structure, which cannot accurately simulate the real ocean wave situation. In the existing technology, some research institutions use wave generators to simulate real ocean waves. However, this method is expensive to test and requires a large test site.
