На чертеже изображена предложенна установка . Она содержит корпус 1, размещенные в нем захваты 2 дл креплени испытываемого образца 3 и св занные с ними две пары т г 4 и 5. Т ги 5 св заны с привдом . Устройство дл передачи нагруз1си от привода на т ги выполнено в виде двух траверс б, жестко закрепленных на паре Tsir 5, двух винтовых пар, имеющих левую и правую резьбу, винты 7 которых вход т в прорези т г 4 перпендикул рно их оси и ввинчены в гайки 8, двух пар рычагов 9, щарнирно св занных одними концами с траверсами 6, а другими - с гайками 8 вин- товых пар, и двух П - образных штанг 1О, жестко св занных в средней части с парой т г 4 и имеющих на концах ролики 11, взаимодействующие с рычагами 9.The drawing shows the proposed installation. It contains a housing 1, the grippers 2 housed therein for fastening the test sample 3 and two pairs connected with them: 4 and 5. The device for transferring the load from the drive to the tractor is made in the form of two cross-arms b, rigidly mounted on a pair of Tsir 5, two screw pairs with left and right threads, screws 7 of which fit into slotted 4 and are perpendicular to their axes and screwed into nuts 8, two pairs of levers 9, hinged together by one ends with cross-beams 6, and the other with 8 screws, and two P-shaped rods 1O, rigidly connected in the middle part with a pair of tons 4 and having the ends of the rollers 11, interacting with the levers 9.
Установка работает следующим, образом.The installation works as follows.
Раст гивающа нагрузка от привода передаетс на т ги 5 непосредственно и на т ги 4 через траверсы 6, рычаги 9 и штанги 10 с роликами 11, кинематически св - занными с рычагами 9,The tensile load from the drive is transmitted to the bars 5 directly and to the bars 4 through the cross bars 6, the levers 9 and the rods 10 with the rollers 11, kinematically connected with the levers 9,
Соотношение усилий и скоростей деформации по двум взаимно перпендикул рным направлени м регулируетс изменением угла оС наклона рычагов 9 по отнощению к т гам 5 от О до 45 с помощью винтовых пар, имеющих левую и правую резьбу. При этом в образце реализуетс напр женноеThe ratio of forces and strain rates in two mutually perpendicular directions is controlled by varying the angle C of the inclination of the levers 9 with respect to the tam 5 from 0 to 45 with screw pairs having left and right threads. In this case, the sample implements the stress
состо ние от простого осевого раст жени ( оС о) до равномерного двухосного раст жени ( об 45 ).condition from simple axial stretching (oC o) to uniform biaxial stretching (about 45).
