摘要：

Advances in engineering solutions in recent few decades caused that conventional fatigue limit (for steels and cast irons given for number of 10 7 cycles) is no more sufficient. Construction parts of newly introduced transport vehicles, operating at high velocities and at long distances, reach during their lifetime very high numbers of loading cycles, in order of 10 9 . For this reason, values of fatigue limits for 10 9 cycles must be considered in design and construction of transport vehicles. In this study, authors present how dramatically will change the design of shaft, when fatigue limit for 10 9 cycles is considered. © 2019 Budapest University of Technology and Economics.
