Hybrid Fluid-borne Noise Control in Fluid Power Systems
Fluid-borne noise is caused primarily by unsteady flow from pumps and motors and the instability and cavitation of valves. It is a major contributor to air-borne noise and structural-borne noise in fluid power systems as well as leading to increased fatigue in system components.
This project will research on a hybrid fluid-borne noise control system in fluid power systems. The proposed hybrid system is integrating an active feedforward noise controller with passive tuned flexible hoses. The active noise control system will be designed and implemented to attenuate the dominant harmonic pressure pulsations in the fluid line, while the passive hose will be tuned to provide further attenuation of the residual pulsations. The project aims to attenuate the fluid-borne noise and improve fluid power systems efficiency.
This research will lie in the Centre for Power Transmission and Motion Control. More details can be found: http://www.bath.ac.uk/mech-eng/research/ptmc/index.html
The successful applicant will have opportunities to collaborate with the fluid power and aerospace industries.
