INSTALLATION FOR PHYSICAL-MECHANICAL TESTS OF SAMPLES AT CYCLIC LOADING

摘要

FIELD: machine building. ^ SUBSTANCE: installation for physical-mechanical tests of samples at cyclic loading consists of base, of pusher mounted on it, of drive of cyclic pusher transfer, of sample grippers connected to pusher and of loading former tied with grippers. The loading former is made as a vessel out of flexible material partially filled with working medium. ^ EFFECT: testing at stepped change of loading and unloading intensity; control of step intensity and of ratio between steps in cycle. ^ 3 cl, 1 dwg
