    Abstract

    Analog, digital, and hybrid computers in structural static and fatigue testing under simulated real-life environmental conditions are described. The primary emphasis is on the use of minicomputers for cyclic load control which is still in the experimental stage.

    The primary mission of the authors' laboratory is full scale fatigue testing using flight-by-flight load sequences. The size of the structures and the large number of loading channels require the use of digital computer equipment. Work to combine both the function generation and load control functions is described, together with current progress, which is based on a full size variable sweep wing fatigue test and the testing of a large air vehicle's wing carry-through box structure.
