Testing in combined dynamic environments
The combined dynamic environments of vibration and linear acceleration are experienced by a large number of spacecraft components and other devices. Testing such devices has normally been a two step process in which independent vibration and centrifuge tests were performed. There is a concern that combined effects from these two dynamic environments could cause unexpected operational failures which were not predicted from either analysis or the independent tests. This paper describes the design and performance of a testing facility which combines vibration and centrifuge testing in a single operation. The test facility is called the VIBRAFUGE and utilizes Sandia National Laboratories' 29 foot underground centrifuge with an attached electrodynamic shaker. Also addressed are activities underway at SNL on development of a combined vibration and acoustic test facility.
