Method and device for analyzing resonance
First Claim
1. A device for analyzing and compensating for automotive noise, vibration and harshness (NVH), the device comprising:
- a microprocessor;
a sensor, to measure NVH associated with an automotive system of a vehicle at a frequency and monitor any direct correlation of an environmental condition to a harmonic or resonation problem, the sensor having an output in electrical communication with the microprocessor when vibrations are present at the measured frequency;
a tensioner for adjusting surface tension of a surface of the vehicle to reduce resonance, wherein the tensioner adjusts tension when said microprocessor determines resonance as sensed by the sensor;
wherein the tensioner is located on a surface of a body of the vehicle.
