Repotenciación en la medición de datos de la máquina universal de ensayos del laboratorio de resistencia de materiales de la Facultad de Mecánica.

Abstract

The current degree work consists of improving the data measurement of the universal testing machine through the Effort-Deformation curve, for which the following procedure will be applied for the implementation of the projected electronic-computer system: a diagnostic process will be executed with the respective operation of the Universal Machine and the measuring range, then a study of the pressure transducer and its corresponding signal. A conditioning circuit of four signals will be designed, implemented and selected by means of pressure transmitters at different measurement ranges and an ultrasonic sensor to position the distance of the lower platform with the base, achieving at this point the transformation of the digital-analog signals. Regarding the design of the software for the acquisition of data, the LabVIEW program will be used, since it presents better options in mechanical applications and ease of programming. The installed software will allow the deduction, storage and visualization of the Unitarian Effort-Deformation curve of the different types of digital signals from the tests carried out on the machine with the four working pressure scales that the universal machine has, hence the need that the measuring range is improved, so that the data collection process offers better advantages, such as the collection and processing of a large amount of data, to zero the position data of the plunger and precision in the results. A laboratory guide for tensile and bending tests will be detailed, obtaining the results of the final repowering of the sensors. This will help the user to execute the respective functioning of the software.
