Die Werkstoffbeanspruchung im Wälzkontakt bei hoher Flächenpressung,ermittelt nach Hertz und nach der EHD‐Strömungshypothese

Material stressing at rolling contact with high specific load determined by HERTZian‐ and elastohydrodynamic‐ (EHD) flow hypothesis For the calculation of the material stressing at rolling contact HERTZian distribution of the normal stresses and the tangential stresses within the contact area, which are proportional to the normal stresses, are assumed. This numerical explication is based upon the calculation of the contact fatigue endurance. Taking in consideration the real stress distribution of forces at EHD contact, it can be explained by the EHD flow hypothesis, that at special load constellations the materials stressing leads to higher values.
