Shaker/Vibration Study of Automotive Drives 680050

Vehicle noise resulting from vibration excited by the drive axle can be measured and controlled.
Modifying the gear tooth geometry to assure the optimum design can then be achieved. Further benefits are obtained through determination of the critical path of vibration transmission from the axle into the passenger compartment, pointing the way to vehicle suspension revisions for additional noise control. A vehicle sensitivity index number, and a gear set quality index number are derived which can be matched, thereby specifying a gear set of known quality level for a vehicle of known sensitivity.
