Abstract

The Australian Department of Defence operates a 200 tonne mock-up of a wide-bodied jet for training purposes. A significant structural failure oc- curred during operations in 1992. Following an extensive investigation, the cause of the failure was identified, and a new support system was designed and constructed. To ensure new design loads were not exceeded, a monitor- ing system which included extensive strain gauging of appropriate elements was installed. The monitoring system permitted the determination of the actions transmitted from the bogies to the superstructure through large box sections. The statistical method known as Principal Compon
