In Section 2, the analytical model of a symmetric rotor-GFBs system with HSLDS supports is presented. Section 3 introduces numerical methods of time domain simulation and stability analysis of the rotor system. In Section 4, results and discussions on stability, unbalance and shock vibrations ...
This manipulation requires a change in the stiffness of the rotor supports when it rotates at a speed close to its critical revolutions. The experience showed that efficiency of this manipulation depended not only on the magnitude and rate of the stiffness change but also on the moment of time...
Curiosity also had Timken bearings in the center hub of its carousel system, as it rotated to position sample cups for gathering and analyzing rock, soil, and atmosphere. In addition, two ¼ inch (6.35 mm) Timken bearings run its tiny vacuum pump, which supports the rover’s analytical ...
isolated bridge,using the response spectrum analysis method and by way of considering the equivalent rigidity of the seismic isolation components in the analysis,the nonlinear issue can be simplified as the linear-elastic issue for handling.supports all the CNKI file formats;only supports the PDF ...
The Shifted Rayleigh Mixture Filter for Bearings-Only Tracking of Maneuvering Targets This paper introduces the shifted Rayleigh mixture filter (SRMF), which is based on jump Markov linear systems. The formulation permits the presence of clu... JMC Clark,SA Robbiati,RB Vinter - 《IEEE Transaction...
In addition, in this work only the segments with the smallest fault diameter were used because we were interested in incipient FDD. It should also be emphasized that the vibration signals were normalized before further processing. In that way we managed to overcome one of the main disadvantages ...
In this paper, a modified DE, namely average refined composite multiscale dispersion entropy (ARCMDE) is put forward, which can not only preserve the original data effectively, but also enhance the ability of multiscale fault feature extraction of the IMFs by fusing average refined composite ...
to determine a most appropriate observer maneuver giving complete bearings-only target-motion-analysis observability, comprising the steps of: measuring one or more emitter characteristics; generating based on the emitter characteristic measurements a set of parameters characterizing a set of potential emitte...
