| Summary: | This paper presents a number of thrust-collar-specific effects to consider when simulating the elastohydrodynamic lubrication state. Plate bending can lead to edge loading and can be considered via an FEM model of the solids. When bending is of no concern, the effect of the close outside edge needs to be corrected in half-space deformation theory. Track heating requires a unique version of the Carslaw/Jaeger flash temperature solution for curved trajectories. Especially, the adapted treatment of stiffness effects leads to vastly different results in, e.g., lubrication gap height. |
