Test software increases motor firm's
productivity

LMS International has announced that Audi has selected Test Lab to further increase the productivity of its NVH (Noise, Vibration and Harshness) testing processes.

LMS International announced today that Audi has selected LMS Test Lab to further increase the productivity of its NVH (Noise, Vibration and Harshness) testing processes and to support its strategy of delivering vehicles with superior comfort and sound quality As a longstanding user of LMS testing systems, Audi decided to migrate to the LMS Test Lab software suite and to implement multiple NVH testing systems for lab and field-testing based on the LMS SCADAS III data acquisition front-end

During the extensive evaluation of LMS Test.Lab, NVH engineers at Audi particularly valued the integration of all NVH applications in a single software suite, the productivity and ease-of-use of the integrated process workflow within LMS Test Lab and the flexible power of the LMS SCADAS III data acquisition platform commented LMS.

Audi wanted to strengthen its major investment in NVH testing systems, by its NVH engineering teams tackling the increasing flow and complexity of NVH engineering work and to continue developing distinct comfort and sound 'packages' for the Audi car lines.

In 2003, Audi started the selection process for a complete replacement of NVH testing systems for its testing laboratories and the technology development centres in Ingolstadt and Neckarsulm.

The choice of LMS Test Lab was largely driven by its tight integration of all data acquisition, analysis and reporting tasks and the complete coverage of structural, acoustic, and rotating machinery testing processes.

In addition, the workflow-based interface of Test Lab and its capabilities to incorporate customised testing procedures matched Audi's standardised measurement and analysis procedures said LMS.

Being able to incorporate those in Test Lab, will enable Audi to reach optimal efficiency and high data quality.

In the meanwhile, Audi users already experienced the productivity of working with the same easy-to-use interface for all applications and the flexibility of using the same testing system for laboratory and proving ground testing.

In addition, they particularly value the German user interface that supports their day-to-day testing and analysis tasks.

As part of the agreement, Audi acquired multiple LMS SCADAS III laboratory-based and mobile systems.

The optimal combination of performance, scalability and flexibility made LMS SCADAS III the best-suited platform for Audi's requirements said LMS.

SCADAS III is designed for NVH applications and tightly integrates with TestLab for optimal speed and quality in data acquisition.

The mobile SCADAS III systems allows Audi engineers to perform more analysis during test runs, acquire data with higher-quality standards and get more value out of field-testing campaigns.

The modularity of the systems combined with the large choice of signal conditioning modules enables them to flexibly use the system for a broad spectrum of measurement.

including noise, vibration, torsion and strain, for instance.

Users at Audi can reconfigure the channel count and signal conditioning of their SCADAS III system on the fly, without having to send the system back to LMS for re-calibration.

"Considering the market positioning of Audi, vehicle attributes like comfort and sound quality have become key targets within our development process.

The sound of an Audi, its comfort and dynamic behavior must meet the expectations generated by its design.

NVH engineering at Audi therefore strongly focuses on creating the optimal sound and comfort package for each individual Audi model," commented Dr Ralf Kunkel and Karl Hofer, current and former head of the acoustics engineering department at Audi.

"Taking into account the complexity of NVH engineering, we did not limit our selection criteria to the technical specification of the new testing system.

We also decided to look for a supplier with a solid experience in NVH engineering, with capabilities to assist us in the transition to the new system and with a strong offering in virtual simulation for NVH.

Taking all of this into account, LMS represents the best choice," they added.

"Audi's decision to implement Test Lab is based on the productivity benefits of its integrated and flexible architecture, that covers all NVH applications," stated Filip Pintelon, corporate vice-president and general manager of the Test Division at LMS.

"This important contract confirms the longstanding relationship between Audi and LMS and underscores the capability of Test Lab to support the most demanding manufacturing companies in handling the increased volume and sophistication of NVH testing work," he added.
