Rubber as a material is one of the frequently used materials in mechanical engineering. This article deals with rubber, or flexible pneumatic elements, the main part of which is rubber. We determine the effect of alternating stress on the temperature change in the flexible pneumatic element under this variable load. We describe a device that serves this purpose. This device was designed and manufactured in our department. We also determine the effect of the air pressure of the flexible element on the temperature of the air and the temperature of the flexible elements. We need to find out the magnitude of these temperatures so that we can determine whether these flexible elements can work without significant negative changes in physical properties.
