Abstract

This paper presents a methodology for the failure probability evaluation of a thrust fluid bearing which plays a significant role in stability of machines rotors, mechatronic systems and high precision metrology systems. The static and dynamic behaviour of a fluid bearing depends on several parameters such as external load, the dimensions of the bearing, the supply pressure, the manufacturing capability and fluid properties. In this paper, the analysis of the fluid bearing characteristics is carried out using the finite element method (FEM). Stochastic response surface methodology (SRSM) is used for the approximation of the performance function of a bearing and the reliability is assessed by Monte Carlo simulation (MCS) and first order reliability method (FORM).
