CASE STUDY: Automotive Steering Wheel
The customer contacted DTI regarding attenuation of steering wheel “nibble” which manifests itself as tactile torsional vibration of the steering wheel between 60 mph and 85 mph. The phenomenon is a non-resonance, forced-vibration issue associated with unbalance of the front wheels. Maximum “nibble” occured at about 72 mph in this vehicle.
The steering wheel torsional vibration occurs in the 12 Hz to 15 Hz range, which corresponds to the 60 mph to 85 mph vehicle speed range.
