Development of a Bench for Deformation Measurement Leonardo Ferreira Ribeiro, Luiz Carlos Gomes Sacramento Junior, Raphael Basilio Pires Nonato

Abstract

This paper refers to the construction of a didactic bench for the study of strain in an anodized aluminum clamped beam through strain gage. To the free end of this clamped beam an external concentrated load is applied through standard weights. The analytical method provides the necessary equations for programming the softwares used. The strain data obtained are sent to the HX711 module, which amplifies, filters, and converts the analog signal to digital in order to send it to Arduino^®, where there is a code that reads and sends the data to the supervision station (LabVIEW^®), where they will be stored. Graphs were generated for strain analysis, experiment validation, and relative errors between the results from the analytical calculation and those from the experiment.
