Synthesis of elastic rotatable support of blade swing of a wind turbine based on the elastic coupling [PDF]
Trudy Odesskogo Politehničeskogo Universiteta, 2013 Engineering development requires the creation and use of new high-performance rotary elastic supports for solving not only the problem of shaft-type object orientation around the elements of body and the problem of reduce the friction between them but ...

STUDY OF BENDING VIBRATIONS OF ROTATING SHAFTS WITH ELASTIC CHARACTERISTICS OF SUPPORTS
, 2022 This article proposes a new design of the composite shaft support of technological machines. The action of vibration can lead to a transformation of the internal structure of materials and surface layers, a change in friction conditions and wear on the contact surfaces of machine parts, heating structures.

On the in-plane vibrations of a rotating ring with equi-spaced elastic supports.
Journal of the Japan Society for Aeronautical and Space Sciences, 1990 Vibrational characteristics are obtained for a rotating ring with equi-spaced elastic supports by using the wave approach. Especially, the variation of the natural frequencies with the rotating speed and the number of elastic supports is investigated. Each elastic support is idealized as a combination of concentrated tangential, rotational and radial ...

Development and Validation of a Model to Describe the Bearings Interaction in Rotating Machines Due to Elastic Supporting Structures [PDF]
, 2015 This work focuses on the effects of the flexible supporting structures and on the bearing interaction caused by their elastic deflection on the whole rotor-substructures system [1]. More particularly, a careful theoretical and experimental analysis is performed to understand how the supporting structures influence the rotors behaviour [2, 3] through ...

Monitoring of Bridges by a Laser Pointer: Dynamic Measurement of Support Rotations and Elastic Line Displacements: Methodology and First Test [PDF]
Sensors, 2018 Deck inclination and vertical displacements are among the most important technical parameters to evaluate the health status of a bridge and to verify its bearing capacity. Several methods, both conventional and innovative, are used for structural rotations and displacement monitoring; however, none of these allow, at the same time, precision ...

Relations between Elastic Support and Natural Frequency of Rotating Wing
The Journal of the Japan Society of Aeronautical Engineering, 1953 This paper generally shows how to find natural frequency (bending and torsion) of the blade by series solution, when the supporting points are in nearly elastic condition as the rotating blade of helicopter or gasturbine. And this also shows by numerical calculation natural frequency decrease more quickly when the blade are supported elastically than ...

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1992 In the present report, we have theoretically and experimentally studied the whirling vibration of an asymmetrically rotating elastic shaft supported by asymmetrically elastic pedestals. The steady-state response for this multi-degree-of-freedom system having the terms of variable elasticity was obtained by means of the asymptotic method and the Newton ...

Development and Preliminary Validation of a New Strategy to Model the Interaction Between Rotating Machines and Elastic Supporting Structure [PDF]
, 2015 The accurate modelling of the complicated dynamic phenomena characterizing rotors and support structures represents a critical issue in rotor dynamics field. A correct prediction of the whole system behavior is fundamental to identify safe operating conditions and to avoid instabilities that may lead to erroneous project solutions or possible unwanted ...
