| Amplitude and frequency control of a vibratory pile driver | | This paper describes the digital control of a vibratory
pile driver in which the vibration is generated via two tandem pairs
of electrically driven, geared, contra-rotating eccentrics. Experimental
results are included to show the controller-induced system
dynamics for a variety of load conditions, and to highlight the fact
that, if the relative phase of the eccentric pairs is not controlled, the
natural tendency at high excitation frequency is for the pile driver
to operate with a low vibration amplitude. An analytical technique
for identifying the system parameters is presented, and analytical
performance predictions are compared with experimental results.
Analysis of the power flow in the system shows that, although significant
power transfer occurs between the two electrical drives,
the net power dissipation during pile driving is relatively low. | | ![[img]](http://eprints.lincoln.ac.uk/style/images/fileicons/application_pdf.png)

Abstract
Abstract—This paper describes the digital control of a vibratory pile driver in which the vibration is generated via two tandem pairs of electrically driven, geared, contra-rotating eccentrics. Experimental results are included to show the controller-induced system dynamics for a variety of load condtions, and to highlight the fact that, if the relative phase of the eccentric pairs is not controlled, the
natural tendency at high excitation frequency is for the pile driver to operate with a low vibration amplitude. An analytical technique for identifying the system parameters is presented, and analytical performance predictions are compared with experimental results. Analysis of the power flow in the system shows that, although significant
power transfer occurs between the two electrical drives,
the net power dissipation during pile driving is relatively low.
