Изобретение относитс к приборостроению и может быть использовано дл измерени деформаций низкомодуль ных материалов, например резиновых изделий, образцов и т.п.The invention relates to instrument engineering and can be used to measure deformations of low modulus materials, such as rubber products, samples, and the like.

Известно устройство дл измерени деформаций материалов, содержащее- расположенные вдоль оптической оси источник света, сферический и цилиндрический конденсоры, оптикомеханический блок дл совмещени границ измерительной базы зеркала и фоторегистратор П.A device for measuring material deformations is known, comprising a light source located along the optical axis, spherical and cylindrical condensers, an optical-mechanical unit for combining the boundaries of the measuring base of the mirror and a photographic recorder P.

Недостатком зтого устройства вл етс его конструктивна сложность, а также ограниченность предела динамического режима.The disadvantage of this device is its structural complexity, as well as the limitation of the dynamic mode limit.

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс устройство дл измерени деформаций материалов, содержащее расположенные вдоль оптической оси источник света, два световода , фоторегистратор, торец одногоThe closest to the invention in technical essence and the achieved result is a device for measuring material deformations, containing a light source located along the optical axis, two light guides, a photo recorder, an end face of one

из световодов взаимодействуют с источником света, а торец другого - с фоторегистратором 2.of the light guides interact with the light source, and the end of the other - with the photo recorder 2.

Недостатком зтого устройства вл етс невозможность измерени деформаций низкомодульных материалов, так как пределы измерени ограничены максимальным значением деформации материалов световода. Кроме того, внедрение световода в материал искажает напр женно деформационную картину объекта исследований, а сам эксперимент технически сложен.The disadvantage of this device is the impossibility of measuring the deformations of low-modulus materials, since the measurement limits are limited by the maximum deformation value of the fiber materials. In addition, the introduction of a light guide into the material distorts the stressful deformation pattern of the object of research, and the experiment itself is technically complicated.

Цель изобретени - расширение диапазона измерени низкомодульных материалов .The purpose of the invention is to expand the range of measurement of low modulus materials.

Указанна цель достигаетс тем, что устройство снабжено расположенной коаксиально оси световодов резиновой втулкой, в которую завулканизированы другие торцы световодов.This goal is achieved by the fact that the device is provided with a rubber sleeve located coaxially to the axis of the optical fibers, into which other ends of the optical fibers are vulcanised.

Claims

The drawing shows a device for measuring material deformations. 390 The device contains light guides 2 and 3 located along the optical AXIS source 1, a rubber sleeve 4 and a photographic recorder 5. The device operates as follows. Rubber sleeve 4 is glued to sample 6, made of low modulus material. The light source 2 is illuminated by the input end of the light-water 2. The light passes through the optical fibers 2 and 3 and enters the photo recorder 5. The intensity of the light flux varies depending on the change in the distance f between the fiber optic orbs, vulcanized into a rubber sleeve. The use of a device for measuring the deformations of low-modulus materials, such as rubber products and samples, simplifies the experiment, extends the measurement limits and frequency limits of the deformation measurement. A device for measuring material deformations, comprising a light source located along the optical axis, two light guides, a photographic recorder, the end of one of the light guides interacts with the light source, and the end of the other light guide interacts with a photo recorder, in order to extend the measurement range of low-modulus materials , it is equipped with a rubber sleeve located coaxially to the axis of the optical fibers, into which the other ends of the optical fibers are vulcanized.
