Finding production errors reliably
Actuators are used in numerous places in vehicles, for example for window lifters, mirror adjusters or tailgate openers. With the quality awareness of customers and especially for quiet electric vehicles, the requirements for the quality of actuators are also rising. Acoustic measurements and analyses with the Discom system of sensors and evaluating software reliably find production errors in end-of-line testing and provide the crucial component for safeguarding and improving manufacturing quality.
Measurement simulates human hearing sensation
Annoying noises from actuators are often loud and unpleasant for humans. They must be measured and analyzed from the viewpoint of psychoacoustics. Discom noise analysis therefore simulates the human hearing sensation and “listens” inside the closed system.
Production errors in actuators
The Discom system accurately finds production errors in the EoL testing of actuators like:
- on electric motors
- on transmissions, threaded rods and worm gear drives
- on springs and other expanding and contracting components
TasAlyser software
Measurements are analyzed with the Discom TasAlyser software. The software already has an extensive parameter database with all necessary characteristic quantities for testing actuators. The Discom analysis tools and results database make it possible to monitor production and recognize trends.
Production analysis
WebPal Production Statistics from Discom helps users to track trends, allowing them to detect problems that will occur at an early stage, before they become a true problem.
Discom sensors for acoustic measurements
Für die Aktuatoren-Prüfung bietet Discom unterschiedliche akustische Sensoren an. Alle liefern selbst bei lauten Umgebungsgeräuschen Messergebnisse akkurat ab.
