The distinctive wave vibration of a ring gear affected by mesh effect is investigated based on
the inherent symmetry of spur planetary gears. Compared to prior analysis, this work mainly …

Non-contact measurement of gas turbine rotor blade vibration is a non-trivial task, with no
method available which achieves this aim without some significant draw-backs. This paper …

A new high-order model for in-plane vibrations of rotating rings is developed in this paper.
The inner surface of the ring is connected to an immovable axis through an elastic …

The in-plane steady-state response of a rotating ring on elastic foundation subjected to a
stationary load is investigated theoretically using a high-order model in the framework of the …

Non-intrusive measurement of blade condition within gas turbines is of major interest within
all areas of their use. It is proposed that the measurement of the casing vibration, due to the …

This paper investigates the random vibration of a thin-walled ring subjected to multiple
moving loads from the inside of the ring. A ring gear in a planetary gear train with three …

In this paper, a two-dimensional Timoshenko beam theory is adopted to establish a vibration
analysis model for flexible spur ring gears. Based on this model, the vibration characteristics …

This paper investigates the vibration response from the planetary gearbox with a flexible ring
gear, supported by various constraints, resulting in quite different vibration spectra. The ring …

This paper describes the development of a generic rotordynamic model incorporating rolling
element bearings. Aimed at examining model fidelity requirements for bearings, the work …

Purpose The mounted stationary sensor on the ring casing has become a widely accepted
way to monitor the planetary gear condition and one challenging aspect of this method is the …
