Introduction to Rotor Dynamics

2013
Rotor-dynamics studies the lateral and torsional vibrations of rotating shafts, with the objectives of predicting the rotor vibrations and constraining the vibration level under an acceptable limit. In this chapter we present a short introduction to rotor dynamics to familiarize the reader with the basic concepts and terminologies commonly used in ...

Hingeless rotor dynamics in coordinated turns

31st Structures, Structural Dynamics and Materials Conference, 1990
This paper describes the results of a numerical study of the aeroelastic stability and response of a soft-in-plane, hingeless rotor helicopter undergoing a coordinated steady turn. The combined effects of turn rate, aircraft speed, flight path angle, and direction of turn are discussed.

Rotor Dynamics Methods

2011
The industrial revolution began with reciprocating steam engines as devised by James Watt in 1780, and the 19th century witnessed a rapid expansion in various industrial sectors. Unfortunately, the reciprocating steam engine had several problems because of external combustion and excessive alternating load due to reciprocating masses that limited ...

Dynamic Modeling of Rotors: A Modal Approach

2010
Dynamic modeling of rotors is usually performed under the assumption that the rotating parts of the machine are axially symmetrical, while the non-rotating ones may have no particular symmetry properties. The rotor model, based on the FEM, can be reduced in modal form and then assembled in the FEM model of the stator of the machine.
