The flexible thin-wall bearing, characterized by different kinematic attributes and fault
characteristic frequency in comparison to rolling bearings, introduces a great challenge in …

Thin-walled structures are commonly used in the design of mechanical systems, and their
flexible dynamic problems are the frontiers in engineering research. In this paper, a flexible …

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 …

Campbell diagram is plotted from calculation results to identify a rotating object's critical
speeds. The Campbell diagram is formed by calculating the supported natural frequencies …

Targeting the problems of increasing variable speed working range, complex critical speed
layout and difficult rotor vibration control of helicopter power turbine rotors, a rotor system …
