Theoretical background of method of springs recovering

Abstract

During their life span, high load compression springs lose their resistance and their operating load is reduced. In the course of time, relaxation is observed. The method of compression springs recovering from hardened wire by lowerature thermo-mechanical treatment and contact predeformation is presented. The results of experimental tests on recovering load bearing characteristics of the lot of springs according to a new technology are reported. Load bearing characteristics of recovered springs are theoretically specified. The difference between theoretical and experimental researches does not exceed 3.2 %. This method of springs parameterization is recommended to be used in the development of technology of springs recovering with the use of lowerature thermo-mechanical hardening and contact predeformation
