摘要： A control system for a failure mode testing system is described. The control system employs at least one control algorithm that enables the testing system to be operated at optimal pressure and frequency levels in order to generate a desired system response, such as a desired energy level and desired slope of the fast Fourier transform of the system response. Also described are a pressure dither system and a frequency ringing system for enhancing the operation of the actuator cylinders of the failure mode testing system. All three of the systems can be incorporated, either singularly or in combination, into a computer software program that can be employed to operate and control the failure mode testing system.

摘要： A support system for ground vibration testing of a large flexible structure. The system includes a plurality of light weight lifting mechanisms that impart an upward force sufficient to lift the flexible structure off the ground. The system also includes a plurality of lift beams coupled to the lifting mechanisms in a pendulous manner. Each lift beam attaches to the flexible structure at one of a plurality of designated jack points, and lifts the flexible structure off the ground when the upward force is imparted by the lifting mechanisms. Thus, the flexible structure is thereby pendulously suspending above the ground such that rigid body mode test data is decoupled from first flexible mode test data.

摘要： An apparatus for optimizing the design of a product or component by subjecting the product or component to multiple stimuli, such as temperature, vibration, pressure, ultraviolet radiation, chemical exposure, humidity, mechanical cycling, and mechanical loading, is described. Also described is a method for determining design maturity, technological limits, technological design maturity, predicted technological design maturity, and system target limits of products, components, and systems, respectively.
