Elastic medium is provided with filler of non-compressible material and balls arranged in said medium in such a way that they are spaced one from another and from walls of container by distance equal to 0.5-1.2 of ball diameter. Said balls have diameter 10-30 mm. EFFECT: enhanced strength and efficiency due to lowered energy consumption for tension and compression of elastic medium.
