This thesis documents a PhD level research program, undertaken at the Industrial
Institute Swinburne, Swinburne University of Technology between the years of 1997
and 2000. The research program investigated electromagnetic energy regenerative
vibration damping; the process of recovering energy from damped, vibrating systems.
More specifically, the main research objective was to determine the performance of
regenerative damping for the application of vehicle suspension systems. This question
emerged due to the need for continuous improvement of vehicle efficiency and the
potential benefits possible from the development of regenerative vehicle suspension. It
was noted, at the outset of this research, that previous authors had undertaken research
on particular aspects of regenerative damping systems. However in this research, the
objective was to undertake a broader investigation which would serve to provide a
deeper understanding of the key factors.
The evaluation of regenerative vibration damping performance was achieved by
developing a structured research methodology that began with analysing the overall
requirements of regenerative damping and, based on these requirements, investigated
several important design aspects of the system. The specific design aspects included an
investigation of electromagnetic machines for use as regenerative damping devices. This
analysis concentrated on determining the most promising electromagnetic device
construction based on its damping and regeneration properties. The investigation then
proceeded to develop an 'impedance-matching' regenerative interface, in order to control
the energy flows in the system. This form of device had not been previously developed
for electromagnetic vibration damping, and provided a significant advantage in
maximising energy regeneration while maintaining damping control. The results from
this analysis, when combined with the issues of integrating such a system in vehicle
suspension, were then used to estimate the overall performance of regenerative damping
for vehicle suspension systems.
The methodology and findings in this research program provided a number of
contributing elements to the field, and provided an insight into the development of
regenerative vehicle systems. The findings revealed that electromagnetic regenerative
vibration damping may be feasible for applications such as electric vehicles in which
energy efficiency is a primary concern, and may have other applications in similar
vibrating systems.
