Abstract

An installation for low-number cycle endurance testing comprises a base (1) on which rotatable drive screws (2, 3) are mounted in parallel to each other. The drive screws (2, 3) are kinematically connected to a drive (10). A movable traverse (13) is mounted on the drive screws (2, 3). The installation is also provided with two clamps (14, 15) one of which is mounted on the movable traverse (13) and the other on the base (1). The installation is further provided with an additional drive (18) kinematically connected to the movable traverse (13).

Description

Изобретение относитс  к испытательной технике, а именно к машинам дл  испытани  на малоцикловую усталость При раст жении - сжатии,The invention relates to a testing technique, namely, machines for testing low-cycle fatigue. When stretched - compressed,

Цель изобретени  - повышение производительности испытаний и расширение функциональных возможностей.The purpose of the invention is to increase the test performance and enhance the functionality.

На чертеже изображена схема машины дл  испытани  на малоцикловую Усталость.The drawing shows a diagram of a low-cycle Fatigue testing machine.

Машина содержит основание 1 и св - анную с ним посредством направл ющих колонн 2 и 3 неподвижную травер- 1У 4. Ходовые винты 5 и 6 кинематически св заны с приводом 7. Подвижна  траверса 8 установлена с возможностью перемещени  по ходовым вин- Там 5 и 6 с помощью гаек 9 и 10 соответственно и образует с ними силовую раму. Винты 5 и 6 кинематически св заны с дополнительным приводом 11 и взаимодействуют с подвижной траверсой 8, На основании 1 закреплен пассивный захват 12, а на подвижной траверсе - активный захват 13 дл  установки образца 14,The machine contains the base 1 and the fixed traverse 1 U 4 connected with it by means of the guide columns 2 and 3. The driving screws 5 and 6 are kinematically connected with the drive 7. The mobile traverse 8 is mounted so that it can be moved along the running screws 5 and 6 with the help of nuts 9 and 10, respectively, and forms with them the power frame. Screws 5 and 6 are kinematically connected to the auxiliary drive 11 and interact with the movable crosspiece 8, Passive grip 12 is fixed on base 1, and active grip 13 is mounted on the movable cross bar to install sample 14,

Машина работает следующим обра- ом,The machine works as follows.

При включении привод 7 через кинематическую передачу вращает ходовые йинты 5 и 6 в посто нном направлении, сообща  тем самым одностороннее поступательное перемещение подвижной тра-j sepce 8 со скоростью v( n i, t, где п, - заданное число оборотов привода 7; i| - передаточное отношение Кинематической передачи привод 7 - хо ходовые винты 5 и 6; t - шаг ходового винта 5 и 6,When switched on, the drive 7 rotates the running tires 5 and 6 in a constant direction through a kinematic transmission, thus uniting one-way translational movement of the moving j sepce 8 at a speed v (ni, t, where n is the specified number of turns of the drive 7; i | - gear ratio Kinematic transmission drive 7 - running screws 5 and 6; t - lead screw pitch 5 and 6,

Одновременно дополнительный привод 11 вращает кинематически св занные гAt the same time, the additional drive 11 rotates the kinematically coupled g

ним гайки 9 и 10, которые, взаимодейству  с подвижной траверсой 8, перемещают ее также только в одном, Но V противоположном направлении со скоростью Vz n2-i2- t, где п2 - число оборотов дополнительного привода 11; 1г - передаточное отношение кинематической передачи и дополнительный привод 11 - гайки 9, 10,these nuts are 9 and 10, which, interacting with the movable head plate 8, also move it in only one, But V opposite direction with speed Vz n2-i2- t, where n2 is the number of revolutions of the auxiliary drive 11; 1d - gear ratio of kinematic transmission and additional drive 11 - nuts 9, 10,

Изменение направлени  перемещени  подвижной траверсы 8 дл  создани  переменных нагрузок на образце 14 осуществл етс  путем изменени  числа оборотов одного привода при неизменной скорости другого, что приводит к цик- .лическому нагружению образца 14 раст жением - сжатием,Changing the direction of movement of the movable cross member 8 to create variable loads on the sample 14 is carried out by changing the speed of one drive at a constant speed of the other, which leads to cyclic loading of the sample 14 by stretching - compression
