Sensorless Detection of Mechanical Unbalance in Servodrive with Elastic Coupling
EnergiesThe article focusses on detecting the unbalance of a mechanical component in the electric drive system of a two-mass servomechanism with a permanent magnet synchronous motor (PMSM), which is connected to the load via a long, flexible shaft.

Unbalance of intestinal microbiota in atopic children [PDF]
BMC Microbiology, 2012 Playing a strategic role in the host immune function, the intestinal microbiota has been recently hypothesized to be involved in the etiology of atopy. In order to investigate the gastrointestinal microbial ecology of atopic disease, here we performed a pilot comparative molecular analysis of the faecal microbiota in atopic children and healthy ...

Experiments on dynamic stiffness and damping of tapered bore seals [PDF]
Stiffness and damping were measured in tapered bore ring seals with air as the sealed fluid. Excitation was provided by a known unbalance in the shaft which rotated in the test seals.

The Stability of the Steady State and Bistable Response of a Flexible Rotor Supported on Squeeze Film Dampers [PDF]
, 1991 The stability of the steady state response, the bistable response, and the jumping characteristics are analyzed for the case when a system accelerates or decelerates through the bistable region of a flexible rotor-centralized squeeze film damper system ...
