OROS and FEMTools, Partners to Offer the Solution for Modal Updating

OROS, as a test and measurement specialist, has been offering dedicated solutions for structural dynamics for many years.

Resulting from our strong experience in this field, our instruments are the right answer for ODS, EMA or OMA applications. (Operating Deflection Shapes, Experimental Modal Analysis or Operational Modal Analysis).
But most often the scope of tests is wider than experimental. It’s essential to propose a solution for simulation.

We  always  offer high quality products to our customers. That’s why we work in partnership with Dynamic Design Solutions (DDS) for simulation issues.

Distributed Vibration Measurements on Large Structures

Space Tech Expo will open the doors for 3 days in Bremen, Germany, from 17 to 19 November.
OROS will display its latest technology in noise and vibration test and measurement dedicated to aerospace applications on booth #43.

The challenge of modern aerospace Noise & Vibration (N&V) measurement is mainly related to the structures’ size. Large aircrafts (interior or exterior) require to be checked simultaneously on all measurement points. Long and numerous cables are time-consuming and costly actions.

Torsional Vibration Determination presented by GE and OROS

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.

OROS offered an OR35 analyzer, as a first prize of the CMMNO Industrial Contest

Last December, the Université of Lyon, organized the 4th International Conference on Condition Monitoring of Machinery in Non-stationary Operations (CMMNO).

At the same time, an Industrial Contest has been organized to win an OR35 4-channels analyzer, offered by OROS. Maïa Eolis, a manufacturer of wind turbines, provided with signals from a wind turbine asking to perform order tracking without speed signal.

The CMMNO 2014 contest first prize has been awarded to Robert B. Randall, Michael D. Coats, Wade A. Smith from the university of New South Wales, Australia. The jury was composed by Hugo André from Maïa Eolis and Quentin Leclère from INSA.

Dyson from UK, and SAIGA team at GIPSA-lab from France came respectively 2nd and 3rd.

The objective of this conference was to present the latest research results devoted to extending the scale of applicability of condition monitoring to non-stationary operating conditions or non-steady environments. Topics have been widely covered: Noise and vibration; Condition monitoring; Non-stationary operations Signal processing; Pattern recognition; Modelling of dynamics and fault; Mechatronic machinery.

Contributors came from 18 different countries (Algeria, Australia, Belgium, Colombia, Canada, France, Italy, Lebanon, Morocco, Poland, Russia, Saudi Arabia, Slovenia, Spain, Sweden, Tunisia, UK, USA) and from both the industry and academic institutions.

Balance your Flexible Rotors with the Multiplane Technology

New requirements, related to downsizing and speed increase, generate a renewed need for high speed machines balancing (up to 300 kRPM). Units to be balanced are typically turbochargers but also high speed pumps and turbines.

ORBIGate, the Turbomachinery Vibration Solution, V6.1 Release

ORBIGate, is the dedicated software module for industrial rotating machinery vibration during diagnostics as well as acceptance tests. Thanks to the multichannel instruments, it is especially adapted for transients such as run-ups and shut-downs.  Easy to use, it provides all the tools to bring the highest level of set-up simplicity and efficiency available: Orbits, Shaft Centerline, Bode, Polar, Spectra and Waterfall: ORBIGate is now released in version V6.1.

This new version is compatible with NVGate V9, the OROS software platform, enhancing the Teamwork noise en vibration analyzers technology.

ORBIGate Software Version 6.1 is available for download using your myOROS account (restricted to existing customers). Please make sure to own an active license key; if you don’t, please contact the OROS Customer Care Department.
