INSTALLATION FOR INVESTIGATION OF DEFORMATION PROCESSES OF RUBBER-LIKE MATERIALS AT TEMPERATURE CHANGE

摘要

FIELD: test technology.;SUBSTANCE: use: for investigation of deformation processes of rubber-like materials at temperature change. Summary of invention consists in the fact that installation for investigation of deformation processes of rubber-like materials at temperature change contains parts for sample fixation and for application of load to sample, wherein the sample load acts vertically downward and is created by suspending the load, wherein the installation is provided with parts which enable to measure the displacement of the load application region to the sample, wherein the installation is intended for examining a sample in form of a ring (torus), in which installation the fixed parts are fixed on a flat vertically arranged base, for attachment of sample is used horizontally located rod, fixed on base, in lower part of vertically arranged sample to sample is hingedly attached part in form of rigid clamp, which allows to fix one end part of strong rigid to tension thread, wherein this thread is passed through vertically arranged tube and can move freely without friction downwards and upwards, wherein this tube has external thread and is screwed into thread of threaded part fixed on base, wherein, by rotating said tube, it is possible to determine the coordinate of the load application area to the sample, wherein to the lower part of the thread passing through the tube, a load of known mass is fixed, besides, on the base there fixed are fixed two bolts for installation of the support plate and hold-down plate, which are intended for fixation of the stretched thread in the specified position, at the same time in the working condition this thread passes not only through the tube, but between these planks.;EFFECT: possibility of investigating processes of deformation of a circular specimen from a rubber-like material at temperature change.;1 cl, 2 dwg
