3 Day Open Conference

Combined acoustic and vibration closed loop control solution
Wednesday 19th November 2008
13.00 - 13.20
Auditorium 2

Acoustic and Vibration dynamic response testing is required for flight and space vehicles. Validation as well as Development depends on using closed loop controllers capable of applying these specialized conditions on test articles. A unique approach enables a single system to perform both closed loop acoustic control in 1/3 octave bands and vibration control. This allows the laboratory to maximize their investement and use the same tool for these very different applications. The acoustic control traditionally has been open loop - this approach uses real time 1/3 octave analysis and closed loop which insures the accuracy and safety of the part under test. Dual use as a vibration controller maximizes the investement and the common interface eliminates costly retraining. Designed in safety checks and advanced features protect the test article while validing the design. System design allows hundreds of channels to be acquired in real time.
