SIMPLIFIED METHOD FOR DETERMINING DYNAMIC CHARACTERISTICS OF HYDROSTATODINAMIC BEARING OF THE DOUBLED TYPE

Abstract

A system of equations, which allows a simplified method to determine the amplitude and frequency characteristics of the bearing hydrostatodynamic double type. The generalization to the case of the calculation model of the turbulent flow of the working fluid. A mathematical model, brought to the form adapted to the numerical implementation. Apply the most rational numerical methods for the realization of the theoretical curves. Results nonlinear equations of motion of the disk with the shaft inside the bearing, allowing to analyze the resonance zone and boundary of the stability of the shaft movement in the bearings under consideration. Considered the most sustainable method of numerical implementation of the equations of motion of the shaft with the disc inside the bearing. A sequence of calculation of dynamic characteristics of bearing hydrostatodynamic double type.
