Abstract

See full text

A surface compactor machine includes a compacting surface for compacting a substrate, a first motor, a second motor, a support assembly, and a controller. The first motor rotates a first eccentric shaft. The second motor rotates a second eccentric shaft. The support assembly is connected to the first and second eccentric shafts to transfer vibration forces to the compacting surface. The controller controls speed of at least one of the first and second motors so that a rotational speed of the second eccentric shaft is an integer, greater than 1, times faster than a rotational speed of the first eccentric shaft to generate a composite displacement waveform that vibrates the compacting surface upwards and downwards, wherein the composite displacement waveform includes a zero amplitude coordinate, a wave section located above the zero amplitude coordinate, and a wave section located below the zero amplitude coordinate that is asymmetric relative to the wave section located above the zero amplitude coordinate.
