Description
Определение релаксации напр жений при раст жении обычно бывает затруднено тем обсто тельством, что измерение силы не может быть ироизведеио без соответству1«ш,е11 деформации излимт кицого приспособлени - динамометра- Така деформаци , если она будет одного пор дка с упругой деформацией образца, вызовет разгрузку иоследнего и внесет искажение в величину измеренной силы.Determination of stress relaxation during stretching is usually made difficult by the fact that force measurement cannot be performed without appropriate deformation, el11 deformation or deformation of a dynamometer. Such deformation, if it is of the same order as the elastic deformation of the sample, will cause unload and the latter will distort the magnitude of the measured force.
Предложенный способ испытани материалов на релаксацию при раст жении и высоких температурах свободен от этого недостатка. Отличительна особенность этого способа заключаетс в том, что паден1 е папр жени определ ют ио величине грузов, восстанавливающих первоначальную упругую деформацию образца.The proposed method of testing materials for relaxation under stretching and high temperatures is free from this drawback. A distinctive feature of this method is that the fall of a pair determines the size of the weights that restore the original elastic deformation of the specimen.
Устройство дл осуществлени описываемого способа снабжено двум захватами, электрической печыо и тензометром. Отличительна особенность его заключаетс в там, что оно выполнено с иагружающим приспособлением, расположенным внутри жесткой станины, относительно которой один из указаиных захватов неподвижен, а другой выполнен перемещаемым в направлении оси образца. Перемещение подвижного захвата осуществл етс иосредством нат жной гайки и рычага весов, нагружаемого грузами в мОлМент отклоненн ноказанн тензомет за от заданного. Такое выполнение устройства обеспечивает возможность непрерывного измерени релаксации.A device for carrying out the described method is equipped with two grippers, an electric furnace and a strain gauge. A distinctive feature of it is that there it is made with an unloading device located inside a rigid frame, relative to which one of the specified grips is stationary, and the other is made movable in the direction of the sample axis. Moving the gripper is carried out by means of a tension nut and a scale lever, loaded with loads in the unit. The deflected strain gauge rejected from the specified one. This embodiment of the device provides the possibility of continuous measurement of relaxation.
На чертеже изображена принципиальна схема з стройства.The drawing shows a schematic diagram of the device.
В жесткой станине / устройства устанавливаетс цепочка, состо ща из захватов 2, 3 образца 4. Нижний захват имеет т гу с резьбой, на которую навинчиваетс нат жна гайка 5. Конец т ги шарнирно присоедин етс к нагрузочному рычагу 6 весов, на конце которого подвешена подвеска 7 дл грузов 8.In a rigid frame / device, a chain is established consisting of grips 2, 3 of sample 4. The lower grip has a threaded rod, onto which a tension nut is screwed in. 5. The end of the hinge is pivotally attached to the load lever 6 weights, suspension 7 for loads 8.
