DEVICE FOR TESTING THE STABILITY sea hydraulic engineering constructions

摘要

The invention relates to the experimental fluid mechanics, marine engineering and for equipment for research of hydrodynamic and ice drilling rigs models in experimental ice basin.; Apparatus for testing the stability of marine hydraulic installations, comprising a cooling chamber with a water-filled channel, refrigerating machine with a system of cooling of the ice chamber and towing truck with travel drive along the channel, the speed sensor trolley, a torque and recording apparatus, wherein the unit is positioned symmetrically about the longitudinal axis of the channel and immersed in water with the possibility of regulation of its stiffness in the direction acting on the tested model and longitudinal Poper cing forces, bending moments and torsional provided with horizontal rows of jacks designed to move the trolley and models, and the vertical rows of jacks intended for ensuring vertical impact on the model, made in the form of the indenter.; In addition, the installation horizontal jacks moving trolley are synchronized with the horizontal movement of the model and jacks, as well as vertical jacks, connected with hinges model.; Implementation of the proposed technical solution will improve the efficiency of the installation by allowing testing of offshore structures models. Installation can also find use in studies of the stability of the underwater hydraulic structures, pipelines and communications, under the influence of various drifting ice formations with dimensions comparable to the keel depth of water projected in freezing seas in the process of scientific support projects.
