Performance Analysis of Gas Foil Bearing with Different Foil Pivot Configuration

Abstract EN

A numerical model is developed in order to find out the performance characteristics of gas foil bearings.

The static performance analysis of gas foil bearings has been carried out using an elastic foundation model of the foil.

The steady state results have been compared with the experimental and theoretical results available in the literature.

The characteristics of the bearing have been investigated with change in foil pivot position.

It has been shown that the load carrying capacity is different for different foil pivot positions.

Besides effect of bearing parameters like eccentricity ratio, length to diameter ratio, compliance coefficient, and bearing number on the load carrying capacity with different foil pivot positions have been studied.
