Abstract: This article presents a study of friction noise of timing belt. A historical review is given and an analytical model is proposed to illustrate friction noise generation mechanism. The analysis suggests that the friction noise of timing belt is due to the friction-induced mode coupling of tooth bending modes. A new mechanism of instability for tooth slippage is proposed and used to correlate conventional experimental results and finite element results. It is shown that the friction-induced coupling of tooth vibrational mode could result in unbounded oscillation solution with identical frequency. This illustrates the feature of friction noise of timing belt which has identical frequency and is independent of speed and tension.

Keywords: friction-induced noise; timing belt systems; synchronous belt noise; modelling; vehicle noise; instability; tooth slippage; mode coupling; tooth bending; finite element method; FEM.
