Multibody dynamics simulation of an all-wheel-drive motorcycle for handling and energy efficiency investigations (2017)
Journal Article
Griffin, J., & Popov, A. (in press). Multibody dynamics simulation of an all-wheel-drive motorcycle for handling and energy efficiency investigations. Vehicle System Dynamics, https://doi.org/10.1080/00423114.2017.1296962

It is now possible, through electrical, hydraulic or mechanical means, to power the front wheel of a motorcycle. The aim of this is often to improve performance in limit-handling scenarios including off-road low-traction conditions and on-road high-s...

Simply-supported multi-layered beams for energy harvesting (2016)
Journal Article
Patel, R., Tanaka, Y., McWilliam, S., Mutsuda, H., & Popov, A. A. (2017). Simply-supported multi-layered beams for energy harvesting. Journal of Intelligent Material Systems and Structures, 28(6), https://doi.org/10.1177/1045389X16657418

This paper develops an analytical model for predicting the performance of simply-supported multi-layered piezoelectric vibrating energy harvesters. The model includes the effects of material and geometric nonlinearities, as well as axial pre-tension/... Read More about Simply-supported multi-layered beams for energy harvesting.

Model refinements and experimental testing of highly flexible piezoelectric energy harvesters (2016)
Journal Article
Patel, R., Tanaka, Y., McWilliam, S., Mutsuda, H., & Popov, A. A. (2016). Model refinements and experimental testing of highly flexible piezoelectric energy harvesters. Journal of Sound and Vibration, 368, https://doi.org/10.1016/j.jsv.2016.01.005

This paper addresses limitations to existing analytical models for piezoelectric energy harvesters. The presented model is targeted at predicting behaviours of highly flexible piezoelectric devices (FPEDs) and includes high orders of substrate and pi...

An experimental study of wave power generation using a flexible piezoelectric device (2015)
Journal Article
Tanaka, Y., Oko, T., Mutsuda, H., Patel, R., McWilliam, S., & Popov, A. (2015). An experimental study of wave power generation using a flexible piezoelectric device. Journal of Ocean Technology, 2(1), 28-36

An experimental study of wave power generation using flexible piezoelectric devices (FPEDs) is presented in this paper. Two alternate configurations for harvesting power from waves are proposed. In the first configuration, the FPEDs are installed hor... Read More about An experimental study of wave power generation using a flexible piezoelectric device.

Implementing Determinate Assembly for the Leading Edge Sub-Assembly of Aircraft Wing Manufacture (2014)
Journal Article
Irving, L., Ratchev, S., Popov, A., & Rafla, M. (2014). Implementing Determinate Assembly for the Leading Edge Sub-Assembly of Aircraft Wing Manufacture. SAE International Journal of Aerospace, 7(2), 246-254. https://doi.org/10.4271/2014-01-2252

Copyright © 2014 SAE International. The replacement for the current single-aisle aircraft will need to be manufactured at a rate significantly higher that of current production. One way that production rate can be increased is by reducing the process... Read More about Implementing Determinate Assembly for the Leading Edge Sub-Assembly of Aircraft Wing Manufacture.

Modal Control of Vibration in Rotating Machines and Other Generally Damped Systems (2006)
Presentation / Conference Contribution
Houlston, P. R., Garvey, S. D., & Popov, A. A. (2006). Modal Control of Vibration in Rotating Machines and Other Generally Damped Systems.

Second order matrix equations arise in the description of real dynamical systems. Traditional modal control approaches utilise the eigenvectors of the undamped system to diagonalise the system matrices. A regrettable consequence of this approach is t...

Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing (2006)
Presentation / Conference Contribution
Houlston, P. R., Garvey, S. D., & Popov, A. A. (2006). Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing.

In the context of active control of rotating machines, standard optimal controller methods enable a trade-off to be made between (weighted) mean-square vibrations and (weighted) mean-square currents injected into magnetic bearings. One shortcoming of... Read More about Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing.
