Distributed rotor dynamics

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 1998
The modelling, simulation and analysis of powered rotors with ‘long’ thin shells is investigated. General results enabling the prediction of the torsional vibrational signature of high-speed assemblies under acceleration or braking conditions are outlined. It is demonstrated that simulated response characteristics can be easily obtained and the effect

Aperiodic bursting dynamics of active rotors

Physical Review E, 2022
We report experiments on an active camphor rotor. A camphor rotor is prepared by infusing camphor on a regular rectangular paper strip. It performs self-propelled motion at the air-water interface due to Marangoni driven forces. After some transient (periodic) dynamics, the rotor enters into the aperiodic bursting regime, which is characterized as an ...

Topological Dynamics in Supramolecular Rotors

Nano Letters, 2014
Artificial molecular switches, rotors, and machines are set to establish design rules and applications beyond their biological counterparts. Herein we exemplify the role of noncovalent interactions and transient rearrangements in the complex behavior of supramolecular rotors caged in a 2D metal-organic coordination network.

Rotor Dynamics of Overhung Rotors: Hysteretic Dynamic Behavior

Volume 7: Structures and Dynamics, Parts A and B, 2012
Overhung-configuration rotors are commonly used in the oil, gas and process industries. Examples of this type of equipment include power turbines, Fluid Catalytic Cracking (FCC) expanders, turbochargers and pipeline boosters. Generally, in overhung-configuration rotors, the mass concentration is near the bearing on the overhung end, so the rotor ...

Consistent matrices in rotor dynamic

Meccanica, 1985
The expressions for the consistent mass and gyroscopic matrices for a constant section shaft element are obtained taking into account both shear deformation and transversal inertia. The results are compared with closed form solutions, which are available in simple cases.

Simplified Rotor Dynamics

2011
The helicopter’s main source of propulsion is provided by the main and tail rotor. The aerodynamic forces and moments are nonlinear functions of motion characteristics and controls. Due to the complexity and the uncertainty associated with the aerodynamic phenomena, a detailed model of the forces and moments produced by the main rotor would be of high ...

Bearing influenced rotor dynamics

Tribology International, 1981
Abstract This paper presents a brief summary of the influence of journal bearings in machinery with special reference to rotor dynamic problems. The journal bearings considered are Newtonian, non-Newtonina and magnetohydrodynamic and their influence on the critical speeds and stability of rotors is ...
