Description

Изобретение относитс  к устройствам дл  измерени  деформаций эластичных материалов, например кожи, резины, заменителей кожи и т. п., с применением проволочного датчика сопротивлени .The invention relates to devices for measuring the deformations of elastic materials, for example leather, rubber, skin substitutes, etc., using a wire resistance sensor.

Известные аналогичные устройства дл  тех же целей непригодны дл  измерений больших деформаций исследуемого материала, например при больших его удлинени х, вследствие разрыва проволочных датчиков сопротивлени .Known similar devices for the same purpose are unsuitable for measuring large deformations of the material under investigation, for example, at its large elongations, due to rupture of the wire resistance sensors.

Предлагаемое устройство устран ет указанный недостаток тем, что оно выполнено в виде П-образной скобы, наклеиваемой на испытуемый материал по направлению действи  деформирующих материал усилий и снаблсевной на концах загнутыми параллельно площадке скобы и направленными наружу лапками, и укрепленного на площадке скобы проволочного датчика сопротивлени .The proposed device eliminates this drawback by the fact that it is made in the form of a U-shaped bracket, glued to the test material in the direction of deforming material forces and provided with a clamping paws parallel to the platform and outwards, and a wire resistance sensor attached to the bracket.

На чертеже изображен общий вид предлагаемого устройства.The drawing shows a General view of the proposed device.

Упруга  П-образна  скоба изготовлена из полоски фосфористой или бериллиевой бронзы, толщиной примерно 0,1 - 0,25 мм, с загнутыми параллельно площадке / и направленными нарунсу лапками 2 и 3.The elastic U-shaped bracket is made of a strip of phosphorous or beryllium bronze, approximately 0.1–0.25 mm thick, with legs 2 and 3 bent parallel to the platform / and directed towards the bottom.

На поверхности площадки / скобы укреплен проволочный датчик 4 сопротивлени .A wire resistance sensor 4 is fixed on the surface of the platform / bracket.

Дл  проведени  измерени  скобу приклеивают при помощи лапок 2 и 3 к поверхности исследуемого эластичного материала 5, совмеща  направление продольной оси площадки 7 с направлением действи  деформирующих материал усилий.To measure, the bracket is glued with the help of tabs 2 and 3 to the surface of the elastic material under test 5, combining the direction of the longitudinal axis of the platform 7 with the direction of the forces deforming the material.

Благодар  соответствующей жесткости упругой скобы и смещенному положению ее лапок обеспечиваютс  возможность измерени  больших деформаций исследуемого материала , например до 50% его относ: тельного удлинени , и нормальна  работа проволочного датчика сопротивлени .Due to the appropriate stiffness of the elastic bracket and the offset position of its legs, it is possible to measure large deformations of the material under study, for example up to 50% of its relative elongation, and the normal operation of the wire resistance sensor.
