CABLE DYNAMOMETER Russian patent published in 2004 - IPC

FIELD: experimental hydrodynamics of ships and maritime works.

SUBSTANCE: the invention presents a cable dynamometer and is dealt with the field of experimental hydrodynamics of ships and maritime works, in particular, with the measuring equipment for tests of sample pieces in the marine pilot basin. The dynamometer contains a ring-type elastic element with the tensoresistor transducers, encased between two hard sections, and a cable. The hard sections of the dynamometer are made in the form of flanges with cylindrical grooves, in which thickening rubber rings are installed with a tightness, the flanges are pivotally fixed with cramps for bracing the cable. At that one of them is equipped with a device for the cable hermetic encapsulation. The elastic element of the dynamometer with the tensoresistor transducers is made out of a titanium alloy and placed inside a thin-wall metal tube out of an aluminum alloy, being linked with it by thickening rubber rings with a tightness.

EFFECT: the invention allows to conduct tests of sample models in the marine pilot basin.
