Experimental study of vibroinsulating properties of modern structural polyurethane

Abstract
Modern mechanical engineering often uses polyurethane elastomers as vibroinsulating material. It is difficult to choose the most perfect structural polyurethane among a large number of proposed materials for manufacturing shock absorbers. The article presents experimental research of vibroinsulating properties using two parameters out of five. Based on preliminary tests, an implicit preference is given to one of the three proposed materials. The energy absorption coefficient and the creep of the elastomer are chosen as criteria for evaluating the vibroinsulation properties of polyurethane elastomers. Final choice of polyurethane elastomer for shock absorbers manufacturing could be made if additional tests are carried out for studying three criteria.
