Vibration fatigue comparative test and life prediction for titanium alloy connection structures by HE Shi, LIU Xiaochuan, LIU Haihan, LI Kaixiang, BAI Chunyu

“…In order to study the vibration fatigue performance of typical titanium alloy connection structures，the typical connection structures with different support shapes and rivet spacing are designed based on TC4 titanium alloy thin plates，a vibration fatigue test system is built，and the vibration fatigue performance of different connection structures under narrowband random loads is compared through experiments. The method for predicting the vibration fatigue life of connection structures based on random vibration <i>S</i>_rms-<i>N</i> curves is proposed by introducing stress severity coefficients and fatigue notch factor. …”

Influence of the axial loads of rolling stock on the contact-fatigue life of rails by V. S. Kossov, G. M. Volokhov, O. G. Krasnov, M. N. Ovechnikov, A. L. Protopopov, V. V. Oguenko

“…Considering that the share of freight cars with axial loads of 25 tf does not exceed 15...20 %, then on the routes of its use the service life of rails should be expected to decrease by 3...4 %. The method proposed by the authors for predicting the contact fatigue life of rails with increasing axial loads is advisable to improve in part of the experimental determination of the fatigue and strength characteristics of rail steel from the degree of hardening of the rolling surface, its probabilistic properties and the use of the integral distribution law for vertical forces, taking into account the structure of the freight traffic passing through the section. …”
