摘要

A finite element computer model of the three-dimensional stress–strain state of a shaft–liner system has been developed for investigating materials used under fretting fatigue conditions. The loads of such a system with different ratios between the contact force applied to the liner and the bending force applied to the shaft were considered for the cases where the shaft and the liner of the system are made of steel and a new structural material MONICA. It was established that the von Mises stresses in the shaft and in the liner are minimum in the region of their contact interaction at low levels of compression of the shaft due to its noncontact bending. It is shown that, in some case, the von Mises stresses in the elements of the shaft–liner system made of the MONICA material and, accordingly, the deformation of these elements may be smaller than those of the analogous steel elements.
