Predicting Rediated Noise With Power Flow Finite Element Analysis
2007
Abstract : The development and incorporation of the latest enhancements to the DRDC s PFFEA code are described. The purpose of this work was to make the modeling of the physical environment more realistic, while ensuring that the code runs as efficiently as possible. To this end a new high frequency radiated noise prediction capability has been added. This capability is based on algorithms developed for use in DRDC s AVAST acoustic modeling software tool. In addition to this, a series of upgrades have been made to the PFFFEA processors, PFGEN and POSTPF, in order to ensure compatibility with the latest version of the VASTF program. Finally, a series of validation studies, involving the prediction of the high frequency structural response of DRDC s ring stiffened test cylinder, are also presented.
