In practical applications, air ingestion from the outside environment and cavitation may lead to a foamy lubricant that weakens oil film damping and dynamic performance of rotor system. In this paper, a rigid rotor model is established considering both lateral and pitching vibration under different imbalance excitations to evaluate the effect of air entrainment on rotor system. Tests with three different imbalances are carried out on a rotor-SFD apparatus. Volume controlled air in mixture ranging from pure oil to all air are supplied to the SFD. The transient response of rotor is measured in the experiments. The results show that two-phase flow produces significant influence on the system stability and dynamical response. The damping properties are weakened by entrained air, such as the damping on high frequency components of rolling ball bearing. Super-harmonic resonance and bifurcation are observed, as well as the low frequency components due to air entrainment. <\/jats:p>","DOI":"10.1142\/s0218127417502121","type":"journal-article","created":{"date-parts":[[2018,1,29]],"date-time":"2018-01-29T03:58:05Z","timestamp":1517198285000},"page":"1750212","source":"Crossref","is-referenced-by-count":5,"title":["Dynamic Analysis of a Rotor System Supported on Squeeze Film Damper with Air Entrainment"],"prefix":"10.1142","volume":"27","author":[{"given":"Wei","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Mechanics, Tianjin University, Tianjin 300072, P.
