Like other automotive manufacturers, Ford Motor Company wrestled with a common concern – incessant noise and vibration in chain drive systems. Chain drives have been widely used for power transmission in automotive systems for decades. While chain drives are effective, the undesirable noise and vibrations created have always been a problem. This was particularly the case when Ford detected a severe 1,800–1,900Hz chain noise in a new transmission prototype. Sound pressure levels were 10 -15 dB over nominal values and the cause was unknown.
At Ford, Jack S.P. Liu, Das Ramnath, and Rajesh Adhikari set out to understand the source of the noise and develop simple, analytical models for quick computation of the chain drive system resonances.
