Повний текст джерелаLa industria automovilística está constantemente involucrada en el desarrollo de nuevas metodologías y proyectos con el objetivo de reducir costes. Durante el proceso de diseño de un vehículo, uno de los costes más significativos proviene de la construcción y el ensayo de prototipos para obtener un mejor rendimiento en el comportamiento de la resistencia al choque. Los modelos matemáticos de colisión (crash) desempeñan un papel importante para obtener un conocimiento sólido de la estructura, con el objetivo de lograr un ensayo Euro NCAP exitoso. Sin embargo, la naturaleza compleja de un modelo de crash dificulta la obtención de un diseño robusto que garantice un buen comportamiento de la estructura. Actualmente, en el contexto de los modelos de resistencia al choque, se presta especial atención a las incertidumbres que afectan al proceso de diseño. A pesar de las importantes mejoras y avances científicos en el campo de la cuantificación de la incertidumbre, las simulaciones teóricas y los modelos experimentales no están todavía en perfecta correlación. Partiendo de un modelo computacional de crash que reproduce el comportamiento del sistema estructural, el objetivo de la cuantificación de la incertidumbre es modelar las fuentes de incertidumbre desde los parámetros de entrada (inputs) hasta la respuesta del sistema (output). Esta tesis doctoral presenta una metodología de cuantificación de la incertidumbre para modelos de crash, con el objetivo de evaluar la robustez de la estructura y apoyar en la toma de decisiones. Debido al alto coste computacional de las simulaciones (alrededor de 18 horas para un modelo de coche completo con VPS/Pamcrash), el uso de métodos de Monte Carlo para la cuantificación de la incertidumbre es a menudo inasumible. Para superar esta limitación, en la primera parte de la tesis se presenta un estado del arte, donde se implementan los métodos más relevantes y se aplican a un problema de interés para SEAT. Sin embargo, para tratar modelos de crash se detectan ciertas desventajas en los enfoques clásicos. La variabilidad de los inputs (parámetros de entrada del modelo, p.ej. espesores, propiedades del material, etc.) conduce a problemas no lineales con outputs de alta dimensión. Además, las estructuras presentan múltiples modos ocultos que pueden ser una tarea difícil de detectar y predecir. Por lo tanto, describir estos comportamientos para calcular probabilidades, estadística y análisis de sensibilidad (entre otras medidas) puede proporcionar una potencial herramienta para analizar la robustez de las estructuras en modelos de crash. Para abarcar este problema, el uso de metamodelos (modelos sustitutos) es un enfoque bien establecido, que sustituye al modelo original de Pamcrash para poder evaluar la cuantificación de la incertidumbre (basándose en un número limitado de simulaciones de alto coste computacional en puntos específicos de los inputs). En esta tesis doctoral se estudian varias técnicas, Ordinary Kriging, Polynomial Response Surface y una nueva estrategia basada en el método de Proper Generalized Decomposition denotada por Separated Response Surface. Sin embargo, la incertidumbre de los inputs, los comportamientos no lineales y el gran número de grados de libertad del output conduce a resolver problemas de gran dimensión en los que el metamodelo se puede volver ineficiente o incluso imposible de implementar. Por lo tanto, previo a la definición de un metamodelo, las técnicas de reducción de dimensionalidad (para esta tesis, kernel Principal Component Analysis) presentan ventajas para simplificar la descripción del output, con el objetivo de construir a posteriori un metamodelo eficiente. En esta tesis se desarrolla una metodología adaptativa que combina la reducción de dimensionalidad y el metamodelado para la cuantificación de la incertidumbre para modelos de crash.

ABSTRACT A Study of Automotive Aquaplaning Behavior and Structural Crashworthiness Performance Using Explicit/Implicit Finite Element Methods Student: Yuen-Sheng Chiu Advisor: Syh-Tsang Jenq The purpose of this study concerns with automotive aquaplaning (i.e. hydroplaning) behavior and structural crashworthiness performance using explicit/implicit finite element methods. Parts of current simulations for advanced radial tires and thin-walled square tubes resemble test determined results and/or previous studies. Current numerical scheme in LS-DYNA is adequate and accurate to analyze these specific characteristics due to corresponding verifications in the present work. Investigations of specific tread patterns and triggering mechanisms for tire and tube structures were, respectively, developed to enhance hydroplaning performance and energy-absorption capability. Three types of tread patterns (i.e. smooth, longitudinally-grooved and V-shape grooved patterns) for the inflated radial tires were examined to understand their hydroplaning performances in the current work. The Mooney-Rivlin constitutive law and classical laminated theory (CLT) were used to depict the mechanical behaviors of rubber material and composite reinforcing layers, respectively. The Arbitrary Lagrangian & Eulerian (ALE) formulation was adopted to describe the fluid-structure interaction between tire structure and fluid/void film. The quasi-staticlly compressed numerical results for the inflated tire were in good agreements with test results. Due to the verification of dynamic rolling behavior, the current numerical relationship of normal contact force and operational time was corresponded with that of Nakajima’s study for the inflated smooth tread pattern tire. In order to further check against hydroplaning behavior for the tire, insignificant difference of hydroplaning performances for 195/65R15 tires with smooth, V-shape and longitudinally-grooved tread patterns were reported when compared with Okano and Koishi’s test results in the current work. Effects on hydroplaning velocity of groove width, water film depth, rigid/soft tread patterns, groove spacing and groove number for longitudinally-grooved tread pattern tires were presented. In addition, effects on hydroplaning performance of normal/reverse rotations, pitch angle, pitch number, groove spacing and an inclined front nose for V-shape grooved tread pattern tires were also discussed. After combining the longitudinally-grooved tread pattern tire with an inclined front nose, a 40.2% increase of tire hydroplaning velocity was reported when compared with that of smooth tread pattern tire. With regard to the structural crashworthiness, crushing characteristics of metallic thin-walled square tubes with triggering mechanisms under quasi-static and impact loads were studied. Triggering mechanisms were found to improve energy-absorption capability and initial peak force for tube structures. The power law plasticity strain hardening and elasto-plastic material models considering strain rate effect in LS-DYNA were utilized to describe dynamic stress-strain relationship for metallic thin-walled tubes in question. Good agreements of initial peak force, dynamic mean force and energy-absorption capability between current FE results and Seitzberger’s test results for the thin-walled square tubes with and without foam core materials were reported. Effects on crushing characteristics of discontinuities size, discontinuities shape and pre-indented wall surface were also examined for metallic thin-walled square tubes under quasi-static loading. In addition, insignificant differences of initial peak force, dynamic mean crushing force and specific energy absorption for corrugated thin-walled tubes subjected to an impact loading were presented when compared with that of Ghasemnejad’s study. The theoretical model of corrugated thin-walled tube was reported by Ghasemnejad. An important design concept of current modified theoretical model was proposed to induce the extensional deformed mode by joining bulging mechanisms for the corrugated thin-walled tube model. Good agreements of dynamic mean force between theoretical model and present simulated analysis for modified corrugated thin-walled tubes were reported. This proposed design (i.e. with bulging mechanisms) was effective to significantly enhance 74% specific energy absorption and decrease 75% initial peak force for the corrugated thin-walled tube containing bulging mechanisms with a minimum pitch distance.
