Dynamic Testing: Toward a Multiple Exciter Test
Abstract
Ensuring that the warfighter is supplied with the safest and most reliable weapon systems is a challenging and often extremely varied process. One critical component in qualifying a system is developing and executing a thorough environmental test sequence representative of the anticipated life cycle of the item to be fielded. Effective development of such a test sequence requires clear communication between program office and test personnel. This article concentrates on the critical vibration testing element. The field vibration environment may be described as the simultaneous vibration in three translational and three rotational degrees of freedom. Achieving an accurate 6 degree-of-freedom (6-DOF) replication of this environment in a controlled laboratory setting has taken decades of advancements in vibration control and exciter technology. Below are a short historical path of the evolution of the discipline toward multiple exciter/multiple degree-of-freedom (MDOF) testing, an example of an MDOF vibration system and a discussion of benefits of the technology advancements to the acquisition community.
