Paper Abstract

In order to improve the performance of hydrodynamic journal bearings, the effect of bearing profiles had been investigated using a new approach for shape optimization of hydrodynamic journal bearings based on a profile parameterization method. The optimization process was carried out using Fourier series to describe the bearing profile. The load capacity increases with the increasing order of Fourier series. However the optimized result was almost fully achieved at the Fourier series of order 2. In this paper, three kinds of optimized shapes at the order of the general film thickness equation of 1, 2 and 3 were manufactured and taken as experimental objects respectively. Experimental apparatus was described and some experimental data was presented. The comparison was made for the optimized bearings between numeric values and experimental data. The results show that the new method for shape optimization of hydrodynamic journal bearings based on the general film thickness equation is feasible.
