Abstract: In order to reduce the risk of friction noise in the forward development process of automotive interior in advance, and reduce the trial and error cycle and cost of physical verification. This article introduces the basic principle of material stick-slip effect and material stick-slip friction test, and analyzes the risk level of friction noise caused by commonly used interior materials under different working conditions. A database has been established for the compatibility of friction noise of commonly used interior materials under normal temperature and humidity conditions, providing guidance for material selection in the early stage of product design. At the same time, the engineering application of the interior material noise compatibility database is introduced, guiding the forward control of interior friction noise.

Key words: Interior materials; Stick-slip effect; Friction noise; Compatibility
