Application of a real time signal processor to an on-line correction of a random loading in a fatigue test system

摘要

An application of Solartron 1200 Real Time Signal Processor to correcting a random loading on line in a random fatigue test is presented. By inputting a power spectrum described by a data file to computer, its corresponding random process may be simulated. Since the processor was communicated with a computer, results of signal processing done by processor were sent to the computer periodically during test. The computer did job of pattern matching with correlation coefficient value (CCV) between a loading spectrum and its predetermined target.
