Four different approaches have been proposed to account for flexibility of the bearing rings and the neighboring parts of the shaft and the housing in computing the radial contact forces acting onto the rolling elements. A numerical example is presented to demonstrate efficacy and performance of the developed models. Their applicability is estimated for various conditions.
The possibility of using finite atomic functions of Kravchenko-Rvachev for description of the laws of distribution of the refractive index of the troposphere, the intensity of the scattering from the sea, seasonal behavior unit RCS of land areas with vegetation covering, as well as the spectrum of electromagnetic spikes of lithospheric origin is considered.
A method is proposed for selecting the best displacement parameters for supporting pipes. The influence of lateral displacement of the longitudinal guide pipes in continuous furnaces on the disappearance of the dark spot is studied.
The map of dynamic regimes of a dual-wavelength vertical external cavity surface-emitting laser is built. The areas of continuous wave operation as well as of time-periodic, quasi-periodic and chaotic operation can be marked out in the map. A possible explanation of quite different laser behavior in those area is given.
In this paper we report an exact 3D transparent boundary condition for the parabolic equation in a rectangular computational domain. It is an exact generalization of the well known 2D transparent boundary condition. The condition is based on an assumption that any wave that reaches a boundary of the computational domain is lost. It relates a boundary value of the field at any given longitudinal position...
