Experimental identification of the corrective effect of a non-circular pulley : application to timing belt drive dynamics

Résumé

The work presented in this paperaims at showing experimentally how an oval pulley can generate a corrective effect on a timing belt drive subjected to a 2nd order periodic excitation (fluctuating load torque). For that purpose, a simplified timing belt drive ofa 4-cylinder car engine is reproduced on a test stand. The oval pulley is mounted on the crankshaft axis. Experiments are conducted for different phasing angles of the oval pulley at severaldriving speeds. Pulley angular vibrations and span tension fluctuations are monitored. The results obtained from these experiments are analyzedin the angular and angular frequency domains. The results are compared with experiments performed on a reference case (equivalent circular crankshaft pulley). The study focuses onthe effect of the oval pulley phasing angleon the amplitude of the 2ndorder harmonicsgoverning the angular response of the transmission.
