Case Study

NVH - End of Line Validation

The Challenge

A leading suspension manufacturer was facing continuous product rejections due to NVH (Noise, Vibration and Harshness) issues, resulting in quality concerns, rework, and reduced productivity.

PROLABS Solution

PROLABS upgraded the existing test machine with National Instruments hardware and a customized LabVIEW application for automated End-of-Line NVH measurement and analysis.

The system captures internal mechanical noise at a high 51 kHz sampling rate and compares the measured NVH parameters against predefined requirements, providing an immediate Pass/Fail result.

Traceability

All test results are automatically uploaded to the company database, providing complete product traceability and easy access to historical test data.

The Results

  • Significant reduction in product rejection

  • Faster and more reliable NVH inspection

  • Improved production productivity

  • Automated Pass/Fail decision

  • Complete digital test-result traceability

The Achievement

The upgraded NVH testing solution enabled the customer to achieve better quality control, reduced rejection, and improved production efficiency.
