Testing of Valve Springs under Mechanical and Thermal Loads

Authors: Dr.-Ing. Steffen Rödling, Ing. Manfred Hück, Dipl.-Ing. Matthias Decker, Dipl.-Ing. Sebastian Hoffmann

Published in: MTZ worldwide | Issue 5/2015

Excerpt

The failure of valve springs can result in damage to the whole engine. A new testing procedure developed by IABG provides experimental verification of the fatigue strength of valve springs with very good statistical validation. In order to achieve a sufficiently high number of test results, a specially developed resonance testing machine is used. …
