Computer Aided Static and Fatigue Full-Scale Tests: Possible Applications of Desktop Computers

Abstract

The paper deals with the extensive use of a desktop computer in a recently developed testing facility. The present configuration has been designed for static tests of airframes and for fatigue tests of aircraft structural components.

Only one desktop computer has been installed and a rather sophisticated program allows the calculator to perform all the operations needed to carry out a a structural test (load control, data acquisition, output of significant results). Hydraulic actuators are used to reproduce the load conditions selected for testing structures; the control is ensured by the computer through a feedback system.

The main features of the computer code are discussed and particular emphasis is given to the possibility of performing data acquisition and load control at the same time with a single desktop computer. Also the electronic instruments chosen for the test rig are briefly described. Details are also given about those performances of the testing equipment which depend on the present version of the computer package.
