Taschenbuch. Zustand: Neu. Neuware -The objective of this project is to make a fuzzy expert system by using fuzzy logic, for the prediction of non-linear and complex characteristics of a variable compression engine (VCR) performance and engine emissions. The performance and emissions of engines were studied. The performance parameters such as specific fuel consumption (SFC), brake thermal efficiency (BTE), and emission levels of HC, CO, and NOx were compared by changing compression ratio, blend and brake power.Books on Demand GmbH, Überseering 33, 22297 Hamburg 52 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Coating is done on the materials to reduce the high temperature thermal fatigue, erosion, and formation of oxides. The history of stress intensity factor of the cracked body for different crack lengths is obtained by a closed-form integration of the stress field, using Duhamel¿s theory with principle of superposition and appropriate weight functions. Numerical study of thermal stresses and thermal stress intensity factor in a coated stainless steel plate was done by using FEM based software ABAQUS in this work.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Fatigue crack growth is one of the most important factors in the design of the different mechanical structures. Different models were developed to predict the fatigue crack growth rate. These models cannot be used for different materials to predict the fatigue crack growth rate and examine the effect of different parameters.The neural network is a complicated nonlinear dynamic system with the ability of prediction based on real time information. It is a good tool to develop quantitative predictive method for the fatigue crack growth rate based on experimental data. The prediction of crack retardation using ANN shows greater accuracy as compared to the wheeler model. The overload application reduces the crack growth and results in enhanced fatigue life.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Gas turbine engines are widely used for power generation because of their high efficiency at many places such as in thermal power plant, aircraft engines etc. Turbine blade is one of the most important components of the engine. It is subjected to very severe working conditions at high temperature with high centrifugal forces. At this working condition, blades are prone to fail due to fatigue, creep and environmental failure. Fatigue failure may be thermal fatigue, mechanical fatigue or Thermo-Mechanical Fatigue (TMF). At high temperature and load, creep is one of the major reasons for failure of components. Therefore, it is necessary to predict the life of components for satisfactory working and to avoid damages due to failures. In this study, turbine blade of Nickel based super-alloy INCONEL-718 and variable amplitude type loading is considered for thermal, mechanical and thermo-mechanical analysis. Finite Element Analysis (FEA) software ABAQUS 6.11 is used to carry out analysis. FE-Safe 6.0, life estimation software was used to get the fatigue life of the turbine blade using Morrow strain-life. Creep life was calculated on the basis of Larson Miller Parameter (LMP).Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Steel followed by aluminum alloys are the most frequently welded metal, while some metals cannot be effectively welded. In this work, two different aluminum alloys AA5052-O and AA6061-T6 are joined by MIG welding. Then compared the fatigue life of welded specimen at different loading conditions such as constant amplitude loading, constant amplitude loading with Intermediate single overload, variable amplitude loading. It has been found that welded AA6061-T6 alloy has more life than welded AA5052-O aluminum alloy. Fatigue life of welded alloy 6061-T6 and 5052-O is greater under block loading than intermediate single overloading.Books on Demand GmbH, Überseering 33, 22297 Hamburg 56 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Quality function deployment (QFD) has been widely used to translate customer requirements to a product¿s technical attributes. Correctly rating the importance of every customer requirement is essential to the QFD process because it will largely affect the final target value of a product¿s technical attributes. The success of a product depends not only on whether it meets the customer requirements, but also on how it compares with competitor products. In design evaluation, alternatives are evaluated against several criteria, such as low cost, short lead time and other general minimum requirements to be satisfied. The specification of quantitative performance requirements is necessary in order that the evaluation can be carried out systematically. However, precise (crisp) performance requirements are normally not adequate, for example, it could be stated that the maximum cost of a design is Rs.2000, but Rs.2500 may be still acceptable. Because a requirement like this is imprecise (fuzzy), a fuzzy set or fuzzy number is appropriate for capturing it.Books on Demand GmbH, Überseering 33, 22297 Hamburg 52 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -El despliegue de la función de calidad (QFD) se ha utilizado ampliamente para traducir los requisitos del cliente en atributos técnicos de un producto. Clasificar correctamente la importancia de cada requisito del cliente es esencial para el proceso QFD porque afectará en gran medida al valor objetivo final de los atributos técnicos de un producto. El éxito de un producto no sólo depende de si cumple los requisitos del cliente, sino también de cómo se compara con los productos de la competencia. En la evaluación del diseño, las alternativas se valoran en función de varios criterios, como el bajo coste, el corto plazo de entrega y otros requisitos generales mínimos que deben satisfacerse. La especificación de requisitos cuantitativos de rendimiento es necesaria para que la evaluación pueda llevarse a cabo de forma sistemática. Sin embargo, los requisitos de rendimiento precisos (crisp) no suelen ser adecuados; por ejemplo, podría establecerse que el coste máximo de un diseño es de 2.000 rupias, pero 2.500 rupias pueden seguir siendo aceptables. Dado que un requisito de este tipo es impreciso (difuso), un conjunto difuso o un número difuso son apropiados para capturarlo.Books on Demand GmbH, Überseering 33, 22297 Hamburg 52 pp. Spanisch.

Taschenbuch. Zustand: Neu. Neuware -Los motores de turbina de gas se utilizan ampliamente para la generación de energía debido a su alta eficiencia en muchos lugares, como en centrales térmicas, motores de aviación, etc. El álabe de la turbina es uno de los componentes más importantes del motor. Está sometido a condiciones de trabajo muy severas a alta temperatura con altas fuerzas centrífugas. En estas condiciones de trabajo, los álabes son propensos a fallar debido a la fatiga, la fluencia y los fallos ambientales. El fallo por fatiga puede ser fatiga térmica, fatiga mecánica o fatiga termomecánica (TMF). A altas temperaturas y cargas, la fluencia es uno de los principales motivos de fallo de los componentes. Por lo tanto, es necesario predecir la vida útil de los componentes para que funcionen satisfactoriamente y evitar los daños debidos a los fallos. En este estudio, se considera un álabe de turbina de la superaleación de níquel INCONEL-718 y una carga de amplitud variable para el análisis térmico, mecánico y termomecánico. El software de análisis por elementos finitos (FEA) ABAQUS 6.11 se utiliza para llevar a cabo el análisis. El software de estimación de vida FE-Safe 6.0 se utilizó para obtener la vida de fatiga del álabe de la turbina utilizando la vida de deformación de Morrow. La vida de fluencia se calculó sobre la base del parámetro de Larson Miller (LMP).Books on Demand GmbH, Überseering 33, 22297 Hamburg 84 pp. Spanisch.

Taschenbuch. Zustand: Neu. Neuware -Le déploiement de la fonction qualité (QFD) a été largement utilisé pour traduire les exigences des clients en attributs techniques d'un produit. L'évaluation correcte de l'importance de chaque exigence du client est essentielle au processus QFD car elle affecte largement la valeur cible finale des attributs techniques d'un produit. Le succès d'un produit dépend non seulement de sa capacité à répondre aux exigences du client, mais aussi de sa comparaison avec les produits concurrents. Dans l'évaluation de la conception, les alternatives sont évaluées en fonction de plusieurs critères, tels que le faible coût, le délai de livraison court et d'autres exigences minimales générales à satisfaire. La spécification d'exigences de performance quantitatives est nécessaire pour que l'évaluation puisse être effectuée de manière systématique. Cependant, les exigences de performance précises (crisp) ne sont normalement pas adéquates. Par exemple, on pourrait dire que le coût maximum d'une conception est de 2 000 roupies, mais 2 500 roupies pourraient être acceptables. Comme une telle exigence est imprécise (floue), un ensemble flou ou un nombre flou est approprié pour la capturer.Books on Demand GmbH, Überseering 33, 22297 Hamburg 52 pp. Französisch.

Neuware -Les moteurs à turbine à gaz sont largement utilisés pour la production d'énergie en raison de leur haut rendement dans de nombreux endroits tels que les centrales thermiques, les moteurs d'avion, etc. L'aube de la turbine est l'un des composants les plus importants du moteur. Elle est soumise à des conditions de travail très sévères à haute température avec des forces centrifuges élevées. Dans ces conditions de travail, les aubes sont sujettes à des défaillances dues à la fatigue, au fluage et à l'environnement. La défaillance par fatigue peut être une fatigue thermique, une fatigue mécanique ou une fatigue thermo-mécanique (TMF). À température et charge élevées, le fluage est l'une des principales causes de défaillance des composants. Par conséquent, il est nécessaire de prévoir la durée de vie des composants pour un fonctionnement satisfaisant et pour éviter les dommages dus aux défaillances. Dans cette étude, une aube de turbine en superalliage à base de nickel INCONEL-718 et un chargement de type amplitude variable sont considérés pour une analyse thermique, mécanique et thermo-mécanique. Le logiciel d'analyse par éléments finis (FEA) ABAQUS 6.11 est utilisé pour effectuer l'analyse. FE-Safe 6.0, logiciel d'estimation de la durée de vie, a été utilisé pour obtenir la durée de vie en fatigue de l'aube de turbine en utilisant la déformation de Morrow.

Die korrekte Bewertung der Wichtigkeit jeder Kundenanforderung ist für den QFD-Prozess von entscheidender Bedeutung, da sie den endgültigen Zielwert der technischen Attribute eines Produkts weitgehend beeinflusst. Der Erfolg eines Produkts hängt nicht nur davon ab, ob es die Kundenanforderungen erfüllt, sondern auch davon, wie es im Vergleich zu Konkurrenzprodukten abschneidet. Bei der Entwurfsevaluierung werden die Alternativen anhand mehrerer Kriterien bewertet, z. B. niedrige Kosten, kurze Vorlaufzeit und andere allgemeine Mindestanforderungen, die erfüllt werden müssen. Die Festlegung von quantitativen Leistungsanforderungen ist notwendig, damit die Bewertung systematisch durchgeführt werden kann. Präzise (knackige) Leistungsanforderungen sind jedoch in der Regel nicht ausreichend. So könnte z.B. festgelegt werden, dass die maximalen Kosten eines Entwurfs Rs.2000 betragen, aber Rs.2500 sind vielleicht noch akzeptabel.
