A METHOD AND APPARATUS FOR PROVIDING AN INDICATION OF COMPACTION IN A VIBRATION COMPACTION VEHICLE

摘要

A vibratory compactor includes front (3) and rear (9) frame portions driven by a hydraulic motor (40) and a vibration mechanism (44) on at least one of the frame portions also driven by a hydraulic motor (46). Speed sensors (50, 52) on the vehicle determine the speed of the hydraulic motors, send a signal to a microprocessor (60) on the vehic le which is programmed to convert the signals to indicate the vibrations per unit of longitudinal travel of the vehicle and to display the amount of vibrations on an indicator (32) for the benefit of the operator.
