The theory behind NVH-based end-of-line (EOL) testing
The theory behind NVH-based end-of-line (EOL) testing
The cost of releasing defective products to the market is high. It may cause not only damage you can calculate in money and time, but also it can bring priceless harm to the brand reputation. Therefore, automotive manufacturers and their suppliers focus on efficient end-of-line (EOL) testing reflecting the new ongoing industry trends. The progressing electrification requires new manufacturing technologies, and concepts in lightweight construction, while the customers have increased demands on the noise and vibration quality.
In assemblies for motor vehicles, noise and vibration (NVH) testing at the end-of-line test bench became an important and even central testing method. This testing approach detects assembly and component defects by analyzing sound and vibration samples of the final product in operation and quickly offers reliable results.
Understanding the basic principles of NVH-based EOL testing will set you on the correct path to define an efficient noise and vibration-based EOL test framework fulfilling your demands. Notably, a standardized evaluation of NVH test criteria is essential for the deeper integration of NVH-based testing into quality management systems. Compared to classical physical EOL testing, NVH-based EOL testing always uses analysis functions to extract the required information from the sensor signals. Therefore, depending on the components and effects to be evaluated, adapted signal processing methods are the key. To integrate such a system into the production line, a reliable assertion about the quality of NVH-based test criteria can be made using established measurement system analysis (MSA) methods. This is especially interesting for test criteria with statistically evaluated limits, which are essential for detecting new defect patterns.
Follow this webinar and learn the concept and mechanism of the NVH-based EOL testing and the principles of integrating noise- and vibration-based testing in an industrial quality management environment.
