Essay

New constructions of elastic elements for vibration-proof defices, i.e. for boring shock-absorbers have been made. The mechanic-mathematical sample of elastic element with carrying surface in a view of lengthways cutted culindrikal shell was built and its conduct in the conditions of monotonous and unmonotonous loads was inwestigated. A number of constructions of boring shock-absorbers of various usage with the extended range of operational characteristics was proposed.
