Investigation of in-phase vibration control technology for large multi-shaker test facility

Abstract

This paper describes the background of large multi-shaker test facility’s application. There are three major different methods to deal with the synchronous vibration control issues for these facilities. They are including using digital phase unit, analog phase unit and mimo-vibration controller. Finally, specific engineering application examples in the field of aerospace were given. The test results show that different methods have their own strength and weakness and choices have to be made to resolve the in-phase vibration control problems according to the multi-shaker test facilities’ configuration.
