Abstract: A vibroacoustically coupled test system is provided utilizing acoustic technology combined with fluid dynamics to create a multipurpose dynamic environmental simulation system for use in geological, commercial, medical, military and marine testing and evaluation. The system comprises a support structure interconnected with a reactive surface through which acoustic energy is propagated to simulate environmental conditions. The acoustic energy is generated by a vibration transducer assembly and function generator. Isolators may also be used as reactive support structure for base plates having test structure mounted thereon.
