Abstract

Изобретение относитс  к испытательной технике, к установкам дл  испытаний образцов материалов на прочность. Цель изобретени  - расширение функциональных возможностей путем обеспечени  испытаний как при плавно измен ющихс , так и при циклических и ударных осевых нагрузках. Платформа 2 с приводом вращени  установлена с возможностью поворота относительно оси, перпендикул рной оси ее вращени , прсредством привода 10. В вертикальном положении платформы при малой скорости ее вращени  образец 8, закрепленный в захватах 6, 7, соединенных с грузами, нагружают ударными нагрузками, при которых грузы скольз т в направл ющей 4 и взаимодействуют поочередно с ограничителем 12. При высокой скорости вращени  в вертикальном положении платформы образец нагружаетс  циклической нагрузкой. В горизонтальном положении платформы плавным изменением скорости вращени  измен ют плавно величину осевой нагрузки на образце под действием центробежных сил от вращени  груза. 2 ил.The invention relates to testing equipment, to installations for testing samples of materials for strength. The purpose of the invention is to enhance the functionality by providing tests both with smoothly varying and cyclic and shock axial loads. The rotary drive platform 2 is installed rotatably about an axis perpendicular to its rotation axis by means of the drive 10. In the upright platform at low speed of rotation, sample 8 fixed in grips 6, 7 connected with weights is loaded with shock loads wherein the weights slide in the guide 4 and interact alternately with the stop 12. At a high rotational speed in the vertical position of the platform, the specimen is loaded with a cyclic load. In the horizontal position of the platform, by smoothly varying the speed of rotation, the magnitude of the axial load on the specimen under the action of centrifugal forces from the rotation of the load smoothly changes. 2 Il.
