Topic 4: Energy harvesting dynamic vibration absorbers
Future research directions
Huge potential for the application of classical/modern random
vibration analysis techniques
Vibration energy harvesting under non-Gaussian random
excitations - linear and nonlinear systems
Generalisation of the results to higher dimensional cases (3 or 4
dimensional state-space models)
Stability issues - energy harvesting from instability?
Vibration control - simultaneous control and energy harvesting -
extension of EHDVA - perhaps active control?
Stochastic systems + nonlinearity in higher dimensions
Hybrid piezo-electric and electro magnetic energy harvesting
Multi-scale energy harvesting - incorporating nano-scale
piezoelectric materials such as ZnO, GaN and BN nano tubes and
nano wires
Parameter optimisation
Experimental validationS. Adhikari (Swansea) GIAN 171003L27 Oct-Nov 17 — IIT-M 8 / 8
