OROS and GE Bently Nevada’s
machinery diagnostics service team participated at the 14thEDF/Pprime Poitiers Workshop held at the Futuroscope in Poitiers, France on
October 8 – 9, 2015. This conference is
organized every year between EDF and the Pprime research institute. This was
the opportunity for 150 participants to exchange around the topic of the “Influence
of design and materials journal and thrust bearing performance.” During
this workshop, university professors, engineers from research department of
machinery manufacturers and other key players of the industry from all around
the world gathered to look toward the next generation of turbomachinery’s
design and materials.
Charles Grislin, a
machinery diagnostics engineer at GE Measurement & Control presented a
paper on “Field measurement techniques and instrumentation for torsional
vibration determination”. This article has been written by Charles Grislin, Nicolas Péton from GE
and Guillaume Cousin and Nicolas Denisot, from OROS. This paper describes practical field
challenges of torsional natural frequency determination, using the
OROS noise and vibration analyzers associated with the
Torsion & Twist software module. A poster on a case
study was also presented during conference breaks. This presentation was about
an elevated vibration on an 110MW generator bearing.
