THE IMPACT OF HARDENED TECHNOLOGIES ON THE CICLIC STRENGTH AND DURABILITY OF MACHINE PARTS

shaft, fatigue curve parameters, surface plastic deformation, reliability, mathematical modelAbstract
The regression relationships between the parameters of the quantilе fatigue lines of shafts from the steel 40X subjected to plastic deformation of their working surfaces are revealed. The obtained relationships allow, without long and labour-consuming experiments on fatigue, to calculate the accurate values of the limits of endurance and cyclic durabilities, and using them in calculations of strength and durability.
