Summary on Grant Application Form |
|
The research aims to provide tools for designers to reduce noise output and refine acoustic quality of assembled machines. The current limitation on acoustic design is a lack of data and scientific methodology to characterise vibro-acoustic excitation by the active internal components of a machine, motors, pumps, fans, burners etc. New methods will be developed to characterise burners, condensers and rotating components. All the diverse excitation types - airborne, fluid-borne and structure-borne - will be considered simultaneously using an 'equivalent source methodology'. Additionally, emerging methods to characterise small pumps, fans and motors which have recently been successfully tested on certain machine types will be validated for previously untreated configurations. The developed methods will be used to construct 'Virtual Acoustic Machine Prototypes' of two entire working machines, both to validate the methods and to illustrate their use in an advanced design tool.
