Das Buch behandelt die spezifischen Herausforderungen beim Einsatz von Baggersystemen in engen Tunnelbereichen. Es fokussiert sich auf die Anpassung der Kinematik eines 13-Tonnen-Baggers von L&T KOMATSU Limited, um dessen Funktionalität in einem 5-Meter-Tunnel zu optimieren. Dabei werden die kinematische Reichweite und die entwickelten Kräfte untersucht, gefolgt von einem konzeptionellen Entwurf und der Modellierung mit CATIA und Pro/Engineer. Zudem wird die Analyse des Designs mithilfe von ANSYS thematisiert, um die Effizienz und Leistungsfähigkeit der Maschinen zu steigern.

Focusing on automotive engineering, this book details the concept design of a car's front end through comprehensive packaging studies. It outlines the creation of a detailed 3D model in CATIA and an FEA model using HYPERMESH for impact stress analysis. The analysis examines deformation and energy absorption rates, emphasizing passenger safety in compliance with federal safety standards. Key parameters such as materials, dimensions, shape, and styling are thoroughly analyzed to enhance the crashworthiness of the vehicle's frontal structure, including the body, bumper, and bonnet.

Focusing on the environmental vulnerabilities of polymeric composites, the book explores how moist and variable temperature conditions affect their mechanical properties, particularly in the offshore oil and shipbuilding industries. It highlights the significance of understanding the impact of seawater on composite materials, detailing various studies on moisture absorption and degradation. The research emphasizes that different atmospheric conditions and salt types can lead to distinct degradation mechanisms. A comparative analysis of the effects of seawater on FRP composites is presented.

Focusing on the kinematics of construction equipment, this book explores the adaptation of a 13 Ton class excavator for use in confined tunnel spaces. It addresses the need for improved performance characteristics to meet specific operational requirements, such as a 5-meter tunnel dimension. The text details the study of kinematic reach and forces, alongside the creation of a conceptual design. Additionally, it covers modeling techniques using CATIA and Pro/Engineer, as well as design analysis through ANSYS, providing a comprehensive approach to enhancing excavator functionality in tunnel environments.

Focusing on the development of aluminum alloy-based metal matrix composites (MMCs) reinforced with ZrO2 particulates, this book explores the enhancement of mechanical properties such as strength, hardness, and wear resistance. It details the evaluation of fracture toughness and wear characteristics, alongside microstructural analysis to assess the distribution of ZrO2 within the matrix. The findings highlight the composite's superior performance, making it suitable for various industrial applications while addressing the demands for lightweight and durable materials.
