Análisis Metodológico del Esfuerzo Normal sigma(y) Basado en Deflexión Elástica
Molina, Alejandro (2019-11-02)El problema en la determinación de los esfuerzos normales (𝜎𝑥,𝜎𝑦,𝜏𝑥𝑦) en una sección transversal utilizando como base la deflexión elástica, se basa en el hecho de que las metodologías existentes aún presentan ... -
Análisis Metodológico del Esfuerzo Normal 𝝈y Basado en Deflexión Elástica
Molina, Alejandro (2019-11-02)En este artículo se desarrolla un plan de prueba de vida para un divisor óptico estándar, que permite conocer su tiempo de vida útil y su confiabilidad R(t). De acuerdo con el estándar GR-2866, las variables ambientales a ... -
Discrimination between the lognormal and Weibull distributions by using multiple linear regression
Ortiz Yañez, Jesús Francisco (2018-03-13)In reliability analysis, both the Weibull and the lognormal distributions are analyzed by using the observed data logarithms. While the Weibull data logarithm presents skewness, the lognormal data logarithm is symmetrical. ... -
Fatigue-Life Prediction of Mechanical Element by Using the Weibull Distribution
Piña Monarrez, Manuel Román (2020-09-13)Applying Goodman, Gerber, Soderberg and Elliptical failure theories does not make it possible to determine the span of failure times (cycles to failure-Ni) of a mechanical element, and so in this paper a fatigue-life/Weibull ... -
Generalization of the Hotelling’s t2 decomposition method to the r-chart
Piña Monarrez, Manuel Román (2018-02-14)In this paper, the decomposition of the Mahalanobis distance (MD) and the proportional contribution that each one of the p monitored variables has on the estimated Mahalanobis depth function (MDF) of the R-chart are ... -
Método Weibull para la Reducción de Tiempo de Prueba Ambiental para Divisor Óptico
Barraza-Contreras, Jesús Manuel (2019-09-30)En este artículo se desarrolla un plan de prueba de vida para un divisor óptico estándar, que permite conocer su tiempo de vida útil y su confiabilidad R(t). De acuerdo con el estándar GR-2866, las variables ambientales a ... -
Probabilistic Linear Time-Dependent Stress Beam Analysis and Its Stress-Strength Reliability
Piña Monarrez, Manuel Román (2021-04-12)Based on the principal stress values generated by the bending beam, the material’s strength required at 10^6 cycles is determined depending on time. To determine the stress/strength reliability (R(t)), the stress distribution ... -
Reliability by Using Weibull Distribution Based on Vibration Fatigue Damage
Piña Monarrez, Manuel Román; 187061; Barraza-Contreras, Jesús Manuel; Torres-Villaseñor, Roberto C. (2023-09-14)In this paper, a Weibull probabilistic methodology is proposed with an approach to model vibration fatigue damage accumulation using two parameters: Weibull distribution and a nonlinear fatigue damage accumulation model. ... -
Stress-Based Weibull Method to Select a Ball Bearing and Determine Its Actual Reliability
Piña Monarrez, Manuel Román (2020-11-16)Since the designed bearing’s reliability of 90% was determined in a lab environment, it does not represent the actual used environment. In this paper, a new methodology to determine the actual reliability that corresponds ... -
Stress-strength Weibull analysis with different shape parameter B and probabilistic safety factor
Piña Monarrez, Manuel Román (2020-11-05)Since products are subjected to a random variable stress-strength, their reliability must be determined using the stress-strength analysis. Unfortunately, when both, stress and strength, follow a Weibull distribution with ... -
Vibration Fatigue Life Reliability Cable Trough Assessment by Using Weibull Distribution
Piña Monarrez, Manuel Román; 187061; Barraza-Contreras, Jesús Manuel; Villa-Señor, Roberto C. (2023-03-30)In this paper, the formulation to incorporate the used vibration profile, the stress generated by the product’s application, mass, and the resonance frequency is given. After that, based on the vibration output data, the ... -
Weibull Analysis for Constant and Variant Stress Behavior Using the Alt Method for Single Stress and the Taguchi Method for Several Stress Variables
Piña Monarrez, Manuel Román (2018-04)The article presents the advances on Weibull analysis which let practitioners to plan the data collection test, to fit the Weibull parameters directly from the applied stress values, to determine the capability indices cp ... -
Weibull analysis for normal/accelerated and fatigue random vibration test
Piña Monarrez, Manuel Román (2019-05-16)In this paper, the formula to estimate the sample size n to perform a random vibration test is derived only from the desired reliability (R(t)). Then, the addressed n value is used to design the ISO16750‐3 random vibration ... -
