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.
(1) Automotive interior materials: evaluation of friction performance on seat leather, door panel soft materials, instrument panels, and center console materials.
(2) Automotive functional components: friction noise prediction for armrests, steering wheels, door handles, cup holders, etc.
(3) Material compatibility studies: analysis of stick-slip behavior in different material combinations, predicting potential squeak noise.
(4) Friction performance research: measurement of static friction, dynamic friction, frictional acceleration, friction coefficient, and pulse frequency.
(5) Environmental factor evaluation: assessment of water, oil, dust, and temperature impact on stick-slip and friction properties.
(6) Surface optimization: supports surface treatment, coating improvement, and material formulation optimization.
(7) Quality control and R&D: provides critical parameter references for product development and manufacturing.
(1) VDA 230-206 – German automotive friction noise standard.
(2) BMW PR315, BMW TL 9169300.
(3) VW / Audi / Porsche TL 52064, PV3981.
(4) Ford L400.
(5) TPJLR-00-230 – Jaguar Land Rover friction noise and friction performance standard.
Note: Standards cover automotive friction noise testing, friction force measurement, and environmental simulation requirements.
