OROS NVH Testing Systems - Automotive Testing Expo Europe 2018

Register now for your free entry pass

Visit us on stand #8164 to know more about our NVH testing systems 

OROS designs and manufactures noise & vibration testing systems including application oriented solutions and associated services. It masters the latest technology of data acquisition, digital signal processing as well as application-oriented software. The OROS analysers are flexible enough to handle automotive NVH testing measurements in different test environments: laboratory, in vehicle or production. OROS solutions are dedicated to vehicle, engine and component NVH covering structural dynamics, noise analysis and rotating analysis.
Application software suite includes order tracking & torsion, balancing, sound quality & jury testing, near-field acoustical holography, sound intensity, sound power, modal and transfer path analysis.

OROS technology forum presentation on Wednesday, 6 June

Using psychoacoustics indicators for go/no-go acceptance in production testing Guillaume Cousin, OROS Product Manager. 

Discover in this presentation how loudness, sharpness, roughness and other can contribute efficiently to the go/no-go acceptance decision. Forum program.

Looking for an ultraportable system for noise & vibration measurements?

The field of measurements is moving towards greater portability, simplicity and accuracy. For measurement situations where space constraints apply, ultraportability, autonomy and data compatibility are the most important features required in instruments. Come and discover the new OROS Mobile DAQ System on our exhibition stand (#8164).

OROS sur Mesures Solutions Expo

28-29 mars 2018, Cité Centre de Congrès, Lyon.

Venez nous rendre visite sur le stand B17 et assister à l'exposé thématique la Qualité Sonore au service des tests de fin de chaîne de production par un expert OROS.


Prochainement disponible - OROS MODS, système DAQ ultra-mobile

Quelques images pour en savoir plus (vidéo disponible sur la chaîne youtube OROS).

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.
