Optimization of circular hydrostatic axial journal bearings using a multicriteria approach

Abstract

The solutions that best optimize the design process must be determined using single-criterion and multicriteria approaches. In this research, a multicriteria optimization approach is carried out to determine the circular hydrostatic journal bearing design parameters based on the power requirement, the bearing coefficient and the minimization of the temperature rise of the oil, so that the total performance of the system is optimal. The optimization results of more than two criteria are presented and compared with previous research outcomes. Computational experimental results are given to demonstrate the effectiveness of the present approach.
