DEVICE 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 device for investigation of deformation processes of rubber-like materials at temperature change includes two sliders, which can move along horizontal base, wherein to these sliders parts are attached, on which the tested sample is based during tests, intended for testing at three-point bending, in the middle part of the sample on the sample from below acts force, at that, the device contains long, light, rigid two-rods tension, slides are equipped with downward directed parts for hinged attachment of these rods to them, wherein the horizontal base has a long slot, when each of the two slides moves along the slot, the articulated parts of these rods are moved in this slot, in addition, the device comprises two pieces of flexible, strong, tensile thread, which is intended to wind the sample several times and to engage with the other end of the rod, and for sample loading, during its bending in the central part of sample suspension is installed, on this suspension is suspended cargo, by means of which sample is loaded during its bending, so system is a suspended sample.;EFFECT: possibility of avoiding slippage of supports relative to sample, wherein creep of sample material provides free displacement of sample attachment zones in horizontal direction, wherein in sample there is no appreciable effort in horizontal direction.;1 cl, 2 dwg
