An intuitive workflow for an accurate characterization of active sources

27 November 2020

SOURCE, our dedicated software application for blocked force source characterization and component TPA, generates high-quality and traceable blocked force and TPA calculations. The intuitive workflow and multi-leveled quality checks throughout the measurement, take your NVH development capabilites to a next level. Let’s look into that workflow and its features…

Data Handling

SOURCE is designed for smart and intuitive data handling and works with data from all popular data acquisition systems using ASAM-ODS (ATFX), or from DIRACMATLAB and Universal file format (UFF). The integration with data from major vendors like MBBM MKii, Siemens and Head Acoustics works seamlessly. SOURCE is moreover optimized for handling large data batches; a quick analysis on a few datasets is computed with the same ease and performance as an extensive analysis over several tracking parameters. SOURCE comprises innovative tools to assess data integrity, such as the matrix viewer for FRF data, and Operational Deflection Shape (ODS) animations for operational measurements.

The import of operational data and the extraction of critical time sequences

Source characterization

With all definitions and data in place, the calculation of the forces is a simple next step. SOURCE supports different workflows, think interface forces and blocked forces from a rigid test bench or in-situ measurement. Depending on available data, blocked forces can be converted into interface forces and vice-versa. You can employ mathematical techniques, such as regularization and truncation for matrix inversion. SOURCE uses optional noise and calibration measurements to automatically suggest optimal settings. All this within two ISO standards: ISO/NWIP 21955 and ISO/CD 20270.

Data quality checks ensure a reliable use of FRFs in TPA predictions

Prediction & auralization

In the final phase of the workflow, operational data and FRFs are combined to calculate blocked and interface forces. Combine the forces with (virtual-point transformed) FRFs and NTFs to make TPA predictions and evaluate different transfer paths. The advanced graphing capabilities enable comparing different settings, validating results or building your preferred personal evaluation dashboard. The obtained source descriptions can be combined with vehicle NTFs to make predictions of the interior noise. Optimize by changing NTFs or adjusting rubber bushing stiffnesses. Finally, auralize the results to play back audio over your speakers or headphone. Export audio files to be shared with others or for playback in advanced sound evaluation studios.

SOURCE enables a deeper understanding of the results

SOURCE is the first in market software that embodies the full TPA proposition. A solution covering every aspect of TPA, while saving valuable time and resources with a decline in the required number of prototype variants to get your targetted vibration and sound characteristics. Because we believe in an open ecosystem and an intuitive workflow, SOURCE is the next solution you are looking for!
