Characteristics of Farm Field Profiles as Sources of Tractor Vibration,
Abstract
To evaluate farm field profiles as sources of tractor vibration, profiles of meadows and rough terrains were measured and analyzed. A slope angle measuring apparatus with a vertical gyroscope was made to measure profiles using the slope integration method. Periodic uneveness was not found in the measured profiles, therefore it may be assumed that profiles of farm fields, except plowed field with furrows, are random and non-periodic. Power spectral densities(0.1-3.5c/m) of measured profiles could be approximated by a straight line on a log-log paper.
