Overview: The Theater High Altitude Area Defense (THAAD) missile system is a transportable defensive weapon that uses precision targeting imagery to protect against hostile incoming threats such as tactical and theater ballistic missiles. With a critical design review of a highly complex seeker assembly approaching, an efficient method to validate the design under severe dynamic environments was required. The company increased fidelity of solution using a system dynamic model with highly detailed models of all components and used super elements for efficient modal analysis of the system. It also used modal results and forced response analysis to predict dynamic stresses.
