Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
The Jeep Cherokee (XJ) is a sport utility vehicle manufactured and marketed across a single generation by Jeep in the United States from 1983 (model year 1984) through 2001 — and globally through 2014.

The input is used to determine the optimum time and characteristics for a gear change according ...

Torsional vibration is a concern in the crankshafts of internal combustion engines because it could break the crankshaft itself; shear-off the flywheel; or cause driven belts, gears and attached components to fail, especially when the frequency of the vibration matches the torsional resonant frequency of the crankshaft. Causes of the torsional ...
