Description
II
Изобретение относитс к измерительной технике, а именно к тензометрам дл измерени деформации твердых тел.The invention relates to a measurement technique, namely, strain gauges for measuring the deformation of solids.
Известен тензометр, содержащий два основани , две опоры дл установки на образец , соединенные с основани ми, и две встречно направленные тензобалки, св занные с основани ми 1.A strain gauge is known comprising two bases, two supports for mounting on the sample, connected to the bases, and two counter-directed strain gauges connected to the bases 1.
Недостатками такого тензометра вл ютс низка точность измерений, в св зи с неблагопри тным вли нием перекосов на результаты измерений, и низка чувствитель ность, св занна с отсутствием механической мультипликации деформации образца.The disadvantages of such a strain gauge are low measurement accuracy, due to the adverse effect of distortions on the measurement results, and low sensitivity associated with the lack of mechanical multiplication of the deformation of the sample.
Наиболее близким по технической сущности к предлагаемому вл етс тензометр, содержащий две скобы с опорами дл установки на образец и две параллельные между собой и перпендикул рные скобам тензобалки , концы которых св заны со скобами, а опоры подпружинены в направлении, перпендикул рном плоскости наибольщей жесткости тензобалок 2.The closest in technical essence to the present invention is a strain gauge containing two brackets with supports for mounting on a sample and two parallel and perpendicular brackets of the strain gauge, the ends of which are connected to the brackets, and the supports are spring-loaded in the direction perpendicular to the plane of the most rigid strain gauges 2
Недостатком чанного тензометра вл етс сравнительно низка точность измерений, св занна с неблагопри тным вли ниемThe disadvantage of this strain gauge is the relatively low measurement accuracy due to the adverse effect
перекосов и с недостаточно надежным закреплением скоб на образце.distortions and with insufficiently reliable fastening of staples on the sample.
Цель изобретени - повышение точности измерений.The purpose of the invention is to improve the measurement accuracy.
Поставленна цель достигаетс тем, что тензобалки снабжены на концах призмами, скобы выполнены кажда в виде планки с центральным пр моугольным пазом дл образца и с двум V-образными пазами дл призм и двух встречно направленных и размещенных параллельно планке плоских пружин, на одних концах которых размещены опоры, другие - св заны с планкой , а пазы дл образца и призм выполнены в двух взаимно перпендикул рных плоскост х .The goal is achieved by the fact that the strainer pins are provided with prisms at the ends, the brackets are made in the form of a bar with a central rectangular groove for the sample and with two V-grooves for the prisms and two counter-directed and parallel planar springs at one ends of which the supports, the others are connected to the strip, and the grooves for the sample and the prisms are made in two mutually perpendicular planes.
На фиг. 1 изображен тензометр, общий вид; на фиг. 2 - то же, вид сверху, разрез.FIG. 1 shows a strain gauge, a general view; in fig. 2 - the same, top view, section.
Тензометр содержит две скобы 1 и 2, выполненные кажда из планки 3 с центральным пр моугольным пазом 4, в котором установлен сухарик 5, двух встречно направ ленных плоских пружин 6 и 7 с утонени ми 8 и 9, одни концы которых св заны с планкой 3, а на другнх концах размешеныThe strain gauge contains two brackets 1 and 2, made each of the bar 3 with a central rectangular groove 4, in which a cracker 5 is installed, two oppositely directed flat springs 6 and 7 with thinning 8 and 9, one ends of which are connected to the bar 3 , and at the other ends are placed
