Description
Изобретение относитс к устройствам исследовани релаксации напр жений в полимерных материалах с учетом вли ни на них трени .The invention relates to stress relaxation devices in polymeric materials, taking into account the effect of friction on them.
Наиболее близким по технической сущности и достигаемому эффекту к изобретению вл етс устройство дл измерени релаксации напр жений в полимерных материалах, содержащее раму , размещенный .на ней держатель испытуемого образца, узлы нагружени и измерени нагрузки. Держатель выполнен в виде захвата 13.The closest in technical essence and the achieved effect to the invention is a device for measuring stress relaxation in polymeric materials, comprising a frame, a test specimen holder placed on it, load nodes and load measurements. The holder is made in the form of a grip 13.
Недостатком известного решени вл етс невозможность учета вли нид трени на релаксацию напр жений, так как измерени провод тс в статических услови х.A disadvantage of the known solution is the inability to take into account the influence of friction on stress relaxation, since the measurements are carried out in static conditions.
Цель изобретени - измерение релаксаций напр жений в полимерных материалах с учетом вли ни трени .The purpose of the invention is to measure stress relaxation in polymeric materials, taking into account the effect of friction.
Указанна цель достигаетс за счет того, что устройство дл измерени релаксации напр жений в полимерных материалах, содержащее раму, размещенный на ней держатель испытуемого образца , узлы нагружени и измерени нагрузки, снабжено св занным с узлом нагружени узлом деформации образца, взаимодействующим с. образцом измерителем силы трени , а держатель образца выполнен в виде диска установленного с возможностью вращени .This goal is achieved due to the fact that the device for measuring stress relaxation in polymeric materials, comprising a frame, a test sample holder, load nodes and load measurement, is provided with a deformation specimen connected to the load node, which interacts with. sample gauge friction force, and the sample holder is made in the form of a disc mounted for rotation.
На чертеже изображено устройство дл измерени релаксации напр жений в полимерных материалах, обпщй вид.The drawing shows a device for measuring stress relaxation in polymeric materials, the general view.
Устройство содержит раму 1, держатель 2 образца 3, узел 4 нагружени , узел 5 измерени нагрузки. Устройство The device comprises a frame 1, a holder 2 of sample 3, a loading unit 4, a loading measurement unit 5. Device
10 также снабжено узлом 6 измерени дефо илацин образца 3, измерителем 7 силы , трени . Держатель 2 выполнен в виде диска с возможностью вращени . Узел 4 нагружени включает шток 8 и 10 is also provided with a measurement unit 6 for defoilacin sample 3, a force meter 7, friction meter. The holder 2 is rotatable in the form of a disk. Node 4 loading includes a rod 8 and
15 контргайку 9, узел 6 измерени деформации , содержит, наг ример, индикатор 10 часового типа. Измеритель 7 силы трени снабжен тензодатчикамй (не пока2Q заны).15, the lock nut 9, the deformation measuring unit 6, contains, for example, a 10 hour indicator. The friction force meter 7 is equipped with strain gauges (not yet indicated 2Q).
Устройство работает следующим образом .The device works as follows.
На диск 2 устанавливаетс образец 3 и подпираетс измерителем 7 силы трени , котосалй устанавливаетс противSample 3 is mounted onto disc 2 and supported by a friction force meter 7, which is mounted against
вращени диска 2. Сверху к образцу 3 подводитс шток 8 с помощью узла .4 нагружени и контргайка 9. При этом измер етс нагрузка с помощью узла 5 rotation of the disk 2. From above, the rod 8 is supplied to the sample 3 by means of a loading assembly .4 and a counter nut 9. Herewith, the load is measured by means of the assembly 5
