This work has for objective to structure a software applied the analysis of the reliability of mechanical components. Starting from the results of tests of failures, or temporary experiments, the program calculates the reliability functions, starting from different statistical distributions. Such distributions are appropriate for different analysis types. A more complete study was made for the Distribution of Weibull, that is the classic model for reliability analysis. The statistical theory is involved in this analysis. Graphic exits that allow a better visualization and understanding of the project conditions are presented together with the reliability functions. This work turns more accessible the concepts related to the theory of the reliability of components and systems, facilitating larger understanding and familiarity.

The main objective of this work is the analysis of the reliability of mechanical components, as well as its application in failure tests commonly used in the practice, in this case, tests for obtaining and verification of the natural frequency associated to the first vibrational mode of turbocharger blades. Of the statistical theory applied to tests of components, it was made a rising of the types of used tests and its application with respect to the sampling of the population in study. Soon after, an analysis is proceeded on correlation and regression of the obtained data of the tests and of the adjustment of curves. Experimental tests were accomplished in the bank of tests of Schwitzer in two different models of turbocharger, and mensured the natural frequencies in a certain number of samples, all of them with the same number of blades..

The main objective of this work is the structuration of a complete software for reliability analysis of mechanical components, as well its application in failure tests to obtain useful lifetime employed in some advanced maintenance techniques. The software has a theoretical revision for better understanding of the basics concepts of reliability and it presents procedure to evaluate reliability functions through the main statistical methods. Making use of the statistical theory applied to components and systems trials, the most common types of trials and their application to the sample population were studied. Basics concepts as parametric and non-parametric trials and descriptive statistic are applied. Afterwards, it was made an analysis of correlation and regression of the obtained data from the trials and curve fitting (lineal, logarithmic, exponential, etc.).
