"The process of design and construction of a machine for fatigue test, instrumented, for determining the properties of fatigue of materials in a controlled environment, with the ability to test, at the same time, bodies of evidence with individual loads and environments.The present invention relates to a machine for fatigue test, instrumented, for determining the properties of fatigue of materials in a controlled environment, with the ability to practice at the same time 10 bodies of evidence with individual loads and environments, and its process of Fabr Branded, consisting of a solid basis, shafts, bearings, motor, reducer, frequency inverter.The counter of the number of cycles, load cell, recirculation pump and fluid chambers to submit the bodies of evidence in diverse environments, bolts and nuts. The efforts are applied to the body of evidence by means of a cam system specially designed for this purpose.The values of loads applied to the body of evidence by means of the eccentrics are controlled by the load cell. The purpose of the fatigue tests is to measure the number of cycles that take each body of evidence to the failure or the infinite life under a voltage previously set. To measure the number of cycles using a electronic meter designed and built for this purpose.This machine works based on the bending fatigue of the body of the reverse proof. The knowledge of the behaviour of these materials is of great importance in its use in design of structure and components of the nuclear industries and conventional.
