(54) УСТАНОВКА ДЛЯ ИСПЫТАНИЯ ПЛОСКИХ ОБРАЗЦОВ НА УСТАЛОСТЬ ПРИ ЧИСТОМ ИЗГИБЕ(54) INSTALLATION FOR TESTING OF FLAT PATTERNS FOR TIRING WITH CLEAN BEND
Изобретение относитс к исследовани м прочностыьж свойств материалов, а именно к установкам дл испытани на усталость при чистом изгибе.The invention relates to studies of the strength properties of materials, in particular to installations for testing fatigue in pure bending.
Известна установка дл усталостных испытаний плоских образцов при чистом изгибе, содержаща кривошипно-шатунный возбудитель циклических нагрузок, механизм чистого изгиба, включакйщй поперечную планку, перехбдные звень , шарнирыгсоедин нкцие переходные звень , зажимы дл испытуемого образца, установленные на вспомогательных пластинах, и шарнирные опоры дл вспомогательных пластин , не преп тствующие их осевым перемещени м гп.A known installation for fatigue testing of flat specimens under clean bending, comprising a crank drive cyclic load causative agent, a clean bending mechanism including a cross bar, interchipes, hinges, transition elements, clamps for the test specimen mounted on auxiliary plates, and hinged joints transitional parts, clamps for the test specimen mounted on auxiliary plates, and hinged joints transitional parts, clamps for the test specimen mounted on auxiliary plates, and hinged joints are transitional parts, clamps for the test specimen mounted on auxiliary plates, and hinged joints are transitional parts, clamps for the test specimen mounted on auxiliary plates, and hinges plates that do not prevent their axial displacement.
Недостатком установки вл етс возможность искажени напр женного состо ни чистого изгиба вследствие малых осевых перемещений пластин и св занного с ними образца.The disadvantage of the installation is the possibility of distorting the stress state of pure bending due to small axial displacements of the plates and the sample associated with them.
Наиболее близкой по технической сущности к предлагаемой вл етс установка дл испытани плоских образ-f цов на усталость при чистом изгибе, содержаща станину, кривошипно-шатунный возбудитель циклических нагрузок , две качгшлциес траверсы с захватами дл испытуеьых образцов, соединенные с двум рычагами, одни концы которых шарнирно соединены со стани ной, а другие с шатуном возбудител , имеющим форму вилки 21.The closest to the technical essence of the present invention is a device for testing flat fatigue specimens for fatigue under clean bending, containing a frame, a crank connecting rod and a cyclic load activator, two traverses with grips for test specimens connected to two levers, one ends of which are hingedly connected to the bed, and the others to the exciter-shaped connecting rod, 21-shaped.
Недостатком установки вл етс недостаточна уочность вследствие искажени напр женного состо ни чистого изгиба осевыми силами, возникающими в образце из-за того, что при The disadvantage of the installation is insufficient uocheness due to the distortion of the stress state of pure bending by the axial forces arising in the sample due to the fact that
10 изгибе образца его концы не могут свободно перемещатьс в осевом направлении .10, the bending of the sample, its ends cannot move freely in the axial direction.
Цепь изобретени - повышение точности испытани .The circuit of the invention is to increase the accuracy of the test.

Цель достигаетс благодар тому, что соединение конца одного из рычагов со станиной осуществлено посредством подвески, обеспечивающей перемещение конца рычага в плоскости из20 гиба.The goal is achieved due to the fact that the end of one of the levers is connected to the frame by means of a suspension that provides movement of the end of the lever in the plane of the 20th bend.
На чертеже представлена кинематическа схема установки.The drawing shows a kinematic installation diagram.
Установка содержит станину 1,«ривошипно-шатукный возбудитель 2 цик25 лических нагрузок, две качающиес траверсы 3 и 4 с захватами 5 и 6 дл испытуемых образцов 7.The installation contains a frame 1, a rivoship-shatuk pathogen 2 cyclic loads, two swinging traverses 3 and 4 with grips 5 and 6 for the tested samples 7.
Траверсы 3 и 4 соединены посредством болтовых соединений 8- с двум Traverses 3 and 4 are connected by bolting joints 8- with two
