Measurement and Analysis of Truck Power Train Vibration 760844

Portable instruments and techniques have been developed and are readily available to permit accurate measurement and analysis of annoying truck driveline vibration. Problems such as unbalance of the engine, clutch, cooling fan or other rotating components; looseness; resonance; misalignment; defective bearings and gears can be readily identified by carefully comparing the vibration amplitude, frequency and phase characteristics unique to each problem. Unbalance, perhaps the most common cause of excessive vibration, can normally be corrected in-place.
