A machine for simultaneously carrying out accelerated tests of a different nature on materials. The machine allows short experiments to be carried out, but capable of simulating the behavior of materials during their working life. The materials are simultaneously subjected to very different tests by using a control software of the machine used for carrying out such tests, which software is based on the dimensional analysis. The machine control system software identifies all test parameters that are grouped in so-called adimensional groups. Such groups have the feature of being less than the total number of parameters involved, thus simplifying the analysis and number of tests. The software, through the combination of two special procedures for the analysis of the data entered by the operator, communicates the parameter groups identified to the operator, suggesting said similarity between the tests carried out with different values of the characteristic parameters but with the same value of the characteristic adimensional groups, and identifies the maximum acceleration factor of the tests on the basis of the parameters previously entered, thus using the features of the actuators installed in the test chamber in the best possible way. |
