This thesis describes the software design and implementation
of a microprocessor- based, random load drive and data
acquisition system on a Material Testing System (MTS) machine.
A microprocessor, combination analog input/output module,
magnetic cassette tape recorder, and strain gage network form
a strain data acquisition system for recording sequential
strain peaks and troughs on specimens subjected to flight load
histories. The data will be used to estimate the fraction of
the fatigue life expended in a test specimen.
A high speed digital computer is linked by telephone line
to a microcomputer development system to create the randomization
of fatigue loads specified in Mil Spec 8866 Spectrum A
for use by the MTS machine.
