La Qualité Sonore au service des tests de fin de chaîne de production

Jeudi 29 mars 14h

Traditionnellement utilisée dans le design du son, la qualité sonore est moins connue pour son application de discrimination de pièces défectueuses. Découvrez comment les grands groupes industriels effectuent des tests acoustiques sur leurs composants automobiles, pompes industrielles ou autres appareils ménagers grâce à la qualité sonore.

Sound Quality Solutions to support new trends on EV/HEV Vehicles

Measured and quantifiable perception of sound quality is highly demanded for sound design applications.

To answer to the demand, OROS is promoting two Sound Quality Solutions:

  • Sound Quality Lite to get started with filtered playback and psychoacoustic parameters,
  • Sound Quality Plus brings all the expert tools to cover the various aspects of sound design. 
OROS took the opportunity to present its Advanced Sound Quality Solutions during the Open Technology Forum Presentations at Automotive Testing Korea, focusing on sound quality process from the acquisition to the objective evaluation. (the presentation is available on myOROS after logging onto myOROS).

ORBIGate V6.6 Release - Keep It Moving!

ORBIGate continues to develop in the Turbomachinery market now releasing version 6.6.

Some great new features:

  • Management of kinematic markers: allows frequency lines related to machine gear train kinematics to be located efficiently. It is particularly efficient  in identification of gear mesh and ball bearing frequencies occuring in machines.
  • The instant report facility inserts all active plots from all layouts in your report, on demand and during the test without the need for template predefinition.

In addition, thanks to the continuous development of the OROS range, V6.6 is the version to  use in combination with NVGate 11. (download ORBIGate® Software Version logging onto myOROS)

NVGate 11 - GoToResults Release - Straight to the point!

NVGate 11 is a major version of the OROS Teamwork instruments software platform. In addition to several other improvements, NVGate 11 offers a new user experience with the intuitive GoTo Results interface.

GoToResults is a simple, clear and efficient interface that dramatically reduces  setup time and clarifies  ongoing measurement.
It deals with the main noise and vibration measurement applications (impact hammering, order tracking, NVH waterfall, etc..) in a modern environment.
Experts/analysts can prepare measurements using models that include instructions and instrument setup, whilst final setup is completed on-site with the inputs, displays and save menu options.

Discover in detail how NVGate 11 can improve efficiency of your  noise and vibration  measurements (download by logging onto myOROS)
Contact your local dealer for an upgrade to NVGate V11.xx.

How to Boost Bike Rider Performances on Cobblestone Roads Using OROS Modal Analysis?

This study has been carried out by Samuel Crequy and Xavier Chiementin  from the Research Group in Engineer’s Sciences  at the University of Reims, and Georges Kouroussis from the University of Mons.

Recent studies have demonstrated that more than 7 minutes of vibration exposure on a cobblestone road can have detrimental effects. The aim of this study is to reduce vibration effects on the bike-rider system by applying the Operational Modal Analysis (OMA) method.

The OROS system was selected for its "on-bike" measurements capabilities. The OR35 8 channels instrument was installed in the rider’s backpack (see picture). Data acquisition was processed in multiple runs with 2 references and 14 responses. The first stage was to check repeatability of OMA on sections of cobblestone road (10 passes). The second stage was to acquire the 14 responses on 2 passes for each configuration.

Autonomy, size and weight of the OROS system enabled accurate results to be collected without any influence on the bike-rider system.

OROS Modal software was used for post-analysis. Modal parameter extraction and a shape mode of the bike were provided for each speed and rider mass.

The study led to bike design adjustments for each combined configuration of rider, road and speed.
Thanks to the real-time capabilities of OROS instruments, embedded measurements were successfully monitored during acquisition stages.

OROS latest technology updates enabled the monitoring measurement campaigns from a vehicle close to the bike under test, thanks to the Wi-Fi now integrated in the Teamwork instruments. See the latest features of OR35 Teamwork.

The complete scientific research article was presented at the Analyse Vibratoire Expérimentale (Experimental Vibration Analysis) conference in France, in November 2016.

FdJ is a cycling team taking part in the Tour de France. In preparation for next year’s race, the team has opted to undergo vibration optimization to give them better performance on cobblestone sections of the race stages. In collaboration with Reims University, the dynamics of bike / wheels / tires / human body are measured using OROS equipment (OR35 noise and vibration analyzer), in a pack on the rider’s back.
Initially, measurements are made on indoor tracks for identification of the normal modes. Next, measurements are carried out on cobblestone roads themselves. Sensors are fixed on the saddle tube, the stem, and on the rider’s arms and buttocks. Pedal force is also recorded.
After mode/ performance analyses, specific combinations of wheel types, tire pressures and bike frame dimensions are recommended for each rider.

OROS at Aerospace & Defence Manufacturing Show-ADMS 2017 with AIMIL

AIMIL, the exclusive OROS reseller in India, will display the OROS Noise and Vibration Testing Systems and Solutions to the Aerospace & Defence Manufacturing Show-ADMS 2017. The show is from 17 to 18 August in Bangalore, India.

Government of India is pursuing an ambitious plan to increase the manufacturing capability of Indian defence and aerospace companies for reducing the imports and making the country self-reliant in Defence Sector under the 'Make-in- India' programme. Supporting this national campaign for imparting latest technologies and providing new opportunities for Indian companies in Aerospace and Defence Manufacturing, we are organising the Fourth edition of ADMS.

OROS – Noise and Vibration Testing Solutions Matching your Challenging Tests in Aerospace Applications
OROS is a global manufacturer and solution provider of noise and vibration measurement systems: Instruments, Software and Services. It masters the latest technology of data acquisition, digital signal processing as well as application oriented software for testing and measurement.
Whenever dealing with aerospace or defense crafts, a test is always costly and must be accomplished in a short-time window. At the development stage of aircraft wing structures or satellites, measurements such as modal analysis, often based on multiple shaker excitation, must be successful the first time and data stored safely and securely. Portable, flexible, rugged and accurate, the OROS analyzers handle your noise and vibration tests whatever your environment: test center and transportation, laboratory or in-flight data acquisition. Providing flexible configurations (rack, stand-alone or distributed up to 1000 channels), the OROS solutions enhance your efficiency.
Jet & Rocket Engines Tests: the OROS analyzers record raw data and display the information you need for proper jet engine test. Thanks to the Synchronous Order Analysis, they compute the orders of jet engines during hours of tests required by the propulsion tests centers or flight/taxi tests. The integrated conditioners offer a wide range of transducer interface (ICP, Float, ±40 V, Strain gauges, Thermocouples, PT100, Oversampled tachs). The analyzer is easy to integrate in the test benches.
Data Acquisition: Components integration for in-flight recording requires a portable, rugged and easy recording system. PC free recording is especially very useful for the toughest conditions (direct recording, distributed systems).
Structures Test - Spacecraft structures are checked with the large channel distributed systems. It measures simultaneously up to 1000+ channels for one shot tests. From shaker or loudspeaker excitation the FFT, 1/n Octave and swept-sine offer real-time monitoring and provide immediate results and raw data making the test conclusions faster.
For more than 30 years, OROS solutions are renowned as being designed for the field but powerful enough for any lab.
