...Yinsi Chen; Yuan Li; Heng Liu; Yi Liu Purpose The purpose of this study is to identify the dynamic parameters of journal bearings in asymmetric rotor systems without additional test runs or excitations. Design/methodology/approach An asymmetric rotor-bearing test rig was set up...

...Yinsi Chen; Yi Liu; Yuan Li; Heng Liu Purpose Asymmetric rotating machinery supported by oil film bearings is relatively common in practical applications. The purpose of this study is to propose a method for estimating the oil film parameters of the bearings in an asymmetric rotor-bearing system...
