Abstract
Abstract
This paper describes a computationally efficient, finite element implementation of a generalized short bearing (GSB) formulation to account for mass conservation in cavitated bearing regions. The method is applied to a set of examples representing partial and full journal bearings under transient loads and kinematics. Bearing performance trends are captured well by the GSB formulation when compared with results obtained from a complete two-dimensional formulation and from experiments. The computational speed of the GSB formulation is approximately 40 to 200 times faster than the complete formulation for the examples provided in the paper.
