THERMOMECHANICAL DEVICE OF ACTUATORS

摘要

FIELD: metallurgy.SUBSTANCE: thermomechanical device includes a working member made in the form of one pre-deformed element or several pre-deformed and parallel and/or in-series connected elements from alloy based on titanium with shape memory effect. The working member is made in the form of a rod with working part of cylindrical or rectangular shape and fixing parts in the form of expansions on the rod ends, the sectional area of which is at least by five times more than the sectional area of its working part.EFFECT: achieving maximum possible translational relative movements of the member at variation of its temperature at the temperature interval of reverse martensitic transformation of material.6 dwg, 1 ex
