Изобретение относитс к области исследовани свойств полимерных материалов в услови х сжати .This invention relates to the field of investigating the properties of polymeric materials under compression.
Известен способ определени релаксационных свойств полимерных материалов в уелоВИЯХ объемного сжати с одновременным действием пульсирующей нагрузки.A known method for determining the relaxation properties of polymeric materials in the field of volumetric compression with simultaneous action of a pulsating load.
Цель изобретени - осуществление более точной оценки свойств материалов. Дл этого по 1Предлагаемому способу о релаксационных свойствах полимерных материалов суд т по разности наименьшего амплитудного и статического давлений.The purpose of the invention is the implementation of a more accurate assessment of material properties. For this, according to the proposed method, the relaxation properties of polymeric materials are judged by the difference of the smallest amplitude and static pressures.
На фиг. 1 изображено устройство дл осуществлени предлагаемого способа; на фиг. 2 - график зависимости Р-t, по сн ющий способ.FIG. 1 shows a device for carrying out the proposed method; in fig. 2 is a plot of P-t, illustrating the method.
Устройство (см. фиг. 1) состоит из камеры /, неподвижного плунжера 2 и вспомогательного плунжера 3. Дл замера давлени и температуры полимера в камеру вмонтированы соответствующие датчики 4 и i).The device (see Fig. 1) consists of a chamber /, a fixed plunger 2 and an auxiliary plunger 3. The corresponding sensors 4 and i are mounted in the chamber to measure the pressure and temperature of the polymer.
Способ осуществл етс следующим-образом .The method is carried out as follows.
Исследуемый полимерный материал закладывают в кймеру, котора под действием усили Л перемещаетс относительно плунжеров, в результате чего осуществл етс объемное сжатие полимерного, материала. При этом зThe polymeric material under study is placed in a chimer, which, under the action of an effort L, moves relative to the plungers, as a result of which a bulk compression of the polymeric material is carried out. At the same time
камере устанавливаетс статическое давление, величина которого зависит от усили N. После этого осуществл ют нагружение вспомогательного плунжера пульсирующей натрузкой, вызывающей пульсацию давлени в камере. На фиг. 2 изображены кривые изменени давлени в камере 6 - нри воздействии только статической нагрузки, в камере 7 - при одновременном воздействии статической нагрузки и пульсации плунжера. Остаточное давление РО характеризует релаксационные свойства резиновых смесей в услови х объемного сжати , т. е. РО РШШ- const. где Pconst - давление от статической нагрузки;A static pressure is established in the chamber, the value of which depends on the force N. After that, the auxiliary plunger is loaded with a pulsating load, which causes the pressure in the chamber to pulsate. FIG. Figure 2 shows the curves of pressure changes in chamber 6 — when exposed only to a static load; in chamber 7, under the simultaneous influence of a static load and a plunger pulsation. The residual pressure PO characterizes the relaxation properties of rubber mixtures under conditions of bulk compression, i.e. PO PShSh-const. where Pconst is the pressure from static load;
PMIIII - минимальное пульсирующее давление.PMIIII - minimum pulsating pressure.
