DOI: 10.1177/1350650118818345
Abstract: Experimentation is an effective approach to study the dynamic coefficients of journal bearings because experimental results are more reliable than theoretical calculations. Dynamic coefficients identification based on the unbalance response is more easily implemented than… read more here.
