Stick-Slip – Tribological Test Stand (G-H3P)
The Stick-Slip Tribological Test Stand is designed to predict stick-slip noise (“squeak” or “creak”) in automotive interior and functional components. It measures critical parameters including static friction, dynamic friction, maximum frictional acceleration, vibration frequency, and friction coefficient. The system can simulate environmental conditions such as water, grease, dust, and temperature changes, providing reliable data for material selection, design optimization, and quality control in automotive interiors and functional parts.
