Application
(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.
Standards
(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.
