Development of a methodology taking into account the temperature dependence of material properties in simulation of wear in fast-rotating pivot jewel bearing support
The pivot jewel bearing is an important node of some classes of industrial equipment; at nominal operating modes, the speed of relative rotation of the contact surfaces can reach 103 revolutions per second, while the operating time can be measured in years; under such conditions, it is necessary...

| Summary: | The pivot jewel bearing is an important node of some classes of industrial equipment;
at nominal operating modes, the speed of relative rotation of the contact surfaces
can reach 103 revolutions per second, while the operating time can be measured
in years; under such conditions, it is necessary to take into account the wear of the
contact surfaces; in this paper, a technique for modeling the dry friction wear of a
fast-rotating support pair is proposed, taking into account changes in the properties
of materials due to surface heating, based on solving the wear contact problem
in a stationary formulation using Archard’s law; the effect of taking into account
the temperature dependence of material properties in wear modeling process is
demonstrated. |
