Determination of the Natural Frequency of the Model Spindle System with Active Regulation of the Initial Tension of the Bearings

This article presents a test stand with model high-speed spindle equipped system of active control the preload bearings. was changed by means three piezo actuators. The work results tests during which commercial Abacus measuring equipment from Data Physics used. Its application has shown that angular contact ball bearings is responsive to changes in value these change resulted resonant frequency and its amplitude. dependence between variable corresponding values resonance amplitude system. use for testing allowed preparation showing dynamic behavior spindle. forced signal known parameters, response this excitation recorded at eleven points located on surface entire
