Energy intensity of parts made from polyurethane elastomers

Laboratory testing with determination of strength and energy characteristics of materials for elastic elements of shock absorbers helped to establish that polyurethane elastomers, having the highest values of specific energy consumption and a wide range of alternating dissipation and rigidity characteristics were the best materials. It will allow to create a series of efficient shock absorbers for different elements and units of building constructions. As the result of the analysis performed of different types of steel springs a coefficient of spring’s quality in volume was obtained, as well as coefficient of spring’s quality in weight, coefficients of shape for cylindrical, crew-type and plate springs. These coefficients can help to arrive at the conclusion, regarding the appropriateness of this spring for a particular elements and units of building constructions.
