Qualification of complex systems often involves shock and vibration testing at the component level to ensure each component is robust enough to survive the specified environments. In order for the component testing to adequately satisfy the system requirements, the component must exhibit a similar dynamic response between the laboratory component test and system test. There are several aspects of conventional testing techniques that may impair this objective. Modal substructuring provides a framework to accurately assess the level of impairment introduced in the laboratory setup. If the component response is described in terms of fixed-base modes in both the laboratory and system configurations, we can gain insight into whether the laboratory test is exercising the appropriate damage potential. Further, the fixed-base component response in the system can be used to determine the correct rigid body laboratory fixture input to overcome the errors seen in the standard component test. In this paper, we investigate the effectiveness of reproducing a system shock environment on a simple beam model with an essentially rigid fixture.
