Design of new power supply unit for steel materials contact stress testing device

摘要

The paper deals with steel materials contact stress testing device. Main idea which supports the innovation of the device stems in the necessity of new effective approaches for contact stress material testing because older version of the device was not capable to perform tests with all necessary parameters. With respect to the tests requirements, we have proposed a solution, which allows performing of the contact stress tests in the wide range of parameters. Self-sustaining part of the work is the analysis of the electrical quantities in the input of the power supply unit. Project is realized via cooperation of the Department of the Electrical Power Engineering and Department of the Mechanics of the Materials.)
