Optimization of Shaker Locations for Multiple Shaker Environmental Testing

Mayes, R.L.; Ankers, Luke; Daborn, Phil; Moulder, Tony; Ind, Philip

For flight payloads or systems in free flight, Impedance Matched Multi-Axis Testing (IMMAT) can provide an accurate laboratory reproduction of the flight vibration environment at multiple response locations. IMMAT is performed by controlling multiple shakers attached to the system of interest, usually through slender rods so that the shakers impart negligible moments or shear forces at the attachment.
