DEVICE FOR DETERMINING OPERATIONAL STRENGTH simulate ICE in Tempe REFERENCE EXPERIMENTAL MODELS towed in ice model basin

摘要

Utility model (PM) refers to the area of ​​shipbuilding, and more specifically - to ice towing tank for testing ship models and engineering structures, the question of determining the strength of ice in the ice towing tank, and solves the problem of providing rapid and non-destructive at the same time the ice determining the strength of the simulated ice in the pace of conducting the experiment with models towed in ice towing tank to improve the accuracy and reliability of the model experiment results, while povysh SRI efficient use of the ice rink for holding therein these experiments. This is achieved by the fact that the device is an operational definition of the strength of the simulated ice in the pace of conducting the experiment towed models in the ice towing tank, comprising salinity meters and the ice temperature, means the destruction of cantilever beams with a power dynamometer connected to recording equipment, according to the utility model introduced towing truck with attached to it a test model, and the temperature gauge is formed as a surface temperature meter ice, which is used as ck aniruyuschy ice surface in front of the towed model measuring thermal imager. The imager is placed on a rod attached to the towing trolley located in front of the test model a distance equal to at least eight thicknesses of ice cover basin, and is mounted to the rod of the reciprocating movements transversely to the direction of motion models within 1.1-1.2 the width of the test pattern with a speed specified depending on the speed of the towing test model. When this device is put in an onboard computer, which is arranged on the towing carriage and is connected to a measuring thermal imager. The proposed device is an operational definition of the strength of the simulated ice in the pace of conducting the experiment towed models in the ice towing tank ensures rapid, without destroying the ice pool cover, determining the strength of the simulated ice in the pace of conducting the experiment towed models in the ice towing tank to improve the accuracy and reliability model experiment results, while improving the efficiency of use of the ice rink for holding therein AUC OF DATA experiments that favorably distinguishes it from the prototype.
