- ÍtemAnálisis de falla de un resorte helicoidal de compresión y un perno fracturadoBosa Martínez, Daniel Arturo; Martínez, Favio; Roa Caicedo, Jasson Hernando; Cendales Ladino, Edwin DaríoIn the present project, a failure analysis was made to two mechanical parts, the first a helical spring of a vehicle and the second to a bolt of an industrial machinery that is subtracted thanks to the teacher’s support. The first thing we did was an inspection and visual identification of the parts in the parts of the failures to verify and give an indication of the effect of the failures, secondly in the laboratories of the university foundation the liberators took the analysis of microstructure to identify the type of material of the mechanical parts and finally a Rockwell hardness test was carried out and with the results obtained from the analyzes to be able to identify both the material and the causes of the faults in the pieces analyzed. Through the process it could be found that the failures that affected the pieces, both the bolt and the spring, were affected by fatigue, due it can seen on the marks that due to the expansion of the fault was leaving.
