摘要：

This article presents a sensing thrust bearing based on pressure sensors, utilizing the pressure profile sensitiv-ity to a change in film geometry. The pressure is measured locally via pressure taps, machined into the bear-ing geometry. To evaluate the pressure signals, the sensitivities are derived analytically for both axial and angular displacement. Further, an experimental study was performed at 10 & mu;m film height and 10 MPa sup-ply pressure, which shows a strong agreement with the presented theory and demonstrates the possibility to measure, relative to the film height, large as well as small displacements with a repeatability in the order of sub-& mu;m and sub-& mu;rad.& COPY; 2023 CIRP.
