Abstract

Abstract: In this paper, a universal methodology for investigating the static performance of hydrodynamically lubricated thrust slider bearing based on periodic harmonic is put forward. Because the lubricant film thickness reflects directly the bearing topology structure, the dimensionless lubricant film thickness in the circumference direction is expressed by harmonic functions. Next, each dimensionless pressure distribution related to each lubricant film thickness expanded term is researched. Finally, each dimensionless load capacity related to each pressure distribution is calculated. The results show the inherent relevance among lubricant film thickness expanded term and pressure field and load capacity. Highlights: The dimensionless lubricant film thickness is expressed by harmonic functions. For k ≥1, the dimensionless pressure distribution contains k peaks. For k ≥1, the maximum dimensionless lubricant film pressure value reduces gradually. For k ≥1, the dimensionless bearing load capacity has an overall tendency of decrease.
