TEST STAND FOR THE EXAMINATION OF STEEL CYCLIC PROPERTIES UNDER THE CONDITION OF TEMPERATURE CHANGES

Mechanical fatigue, thermal fatigue, service loads, control of fatigue specimen. In this study, a stand for tests of technical objects under the conditions of thermal and mechanical fatigue is presented. Temperature and load changes and the interrelations between them cause difficulties in controlling and recording basic parameters of fatigue tests in laboratory conditions. The article presents the design and creation of a system for temperature change control and adjustment during fatigue tests under the conditions of thermal loading. The test stand was built through the modernization of a standard strength-testing machine
