This book was released on 2003 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated weapon systems modeling and simulation from concept to operation were treated as essential tool for achieving cost and time reductions which are needed to field new systems. Such tools are being applied to lower the cost and design cycle times from both a design/development and recurring manufacturing perspective. Early identification of problems dramatically reduces costs and improves procurement as well as operations, increasing performance as well as cost effectiveness. The maturing of virtual manufacturing tools led to the review of the various approaches in the NATO framework. Advanced simulation in design, manufacture, and support were treated in four sessions on: Virtual Prototyping and Simulation Tool Integration Qualification by Analysis Design Synthesis Avoiding cost overruns and schedule delays connected to aerodynamic or hydrodynamic performance was treated in three sessions: CFD Modelling Of Non-Linear Phenomena; CFD Validation Procedures; And Error Evaluation Dynamically Coupled CFD.
Download or read book Advanced Modelling and Virtual Product Simulation in the Design and Build of Warships A Practical View written by John L. Martin and published by . This book was released on 2003 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: In considering Reduction of Military Vehicle Acquisition Time and Cost through Advanced Modelling and Virtual Product Simulation' practical experience spanning five years of ship and submarine design and build was reviewed to seek quantification of the contribution made to cost reduction. It concluded that advanced modelling and virtual product simulation must be an integral part of the engineering processes to achieve an advantageous contribution to cost. This involves an effective design process and an efficient means of access to the appropriate product data supporting the geometric model/simulation technologies. The application of Advanced Modelling and Virtual Product Simulation technologies is of limited value when used independently without the close association between the geometric models and the associated functional and physical data attributes which describe the requirement and design solution. This notion can also be illustrated in the traditional case of wood or scaled plastic physical mock-ups of ship or submarine layouts where modelled components were tagged' with a label description, or color coded. i.e. orange to represent electrical routes, grey for HVAC and pre-defined color codes for various pipe systems. Thus an advanced virtual model without any access to underlying data attributes is little more that a pretty picture.

Available in PDF, EPUB and Kindle. Book excerpt: Full of illustrations and photographs, this publication is a comprehensive history of the many innovations in tanks and other military ground vehicles and equipment developed by the engineers at TARDEC, the U.S. Army Tank Automotive Research, Development and Engineering Center. TARDEC was formed in 1946 as an outgrowth of the Detroit Arsenal Tank Plant built during World War II. During the early years, emphasis was placed on evolving new technologies to improve military ground vehicles, culminating in the development of the M1 Abrams tank. Since then, TARDEC has grown to be a key center for advanced technologies for military ground vehicles and equipment. Recent years have brought an explosion of technology development and integration, from hybrid engines to fuel cells, from analytical simulation to enormous physical simulators, and from small robots to entire unmanned vehicles.
Download or read book In touch with the future written by Alberto Gallace and published by OUP Oxford. This book was released on 2014-01-30 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Out of all the human senses, touch is the one that is most often unappreciated, and undervalued. Yet, the surface of the human body, the skin, is actually one huge sheet of tactile receptors. It provides us with the means to connect with our surroundings. Despite the important role that vision plays in our everyday lives, it is the skin that constitutes both the oldest, and by far the largest of our sense organs. The skin protects our body from the external world and, at the same time, informs us about what occurs on its surface. In Touch With The Future explores the science of touch, bringing together the latest findings from cognitive neuroscience about the processing of tactile information in humans. The book provides a comprehensive overview of scientific knowledge regarding themes such as tactile memory, tactile awareness (consciousness), tactile attention, the role of touch in interpersonal and sexual interactions, and the neurological substrates of touch. It highlights the many ways in which our growing understanding of the world of touch can, and in some cases already are, being applied in the real world in everything from the development of virtual reality (VR) environments, tablet PCs, mobile phones, and even teledildonics - the ultimate frontier in terms of adult entertainment. In addition, the book shows how the cognitive neuroscience approach to the study of touch can be applied to help improve the design of many real-world applications/products as well as to many of our everyday experiences, such as those related to the appreciation of food, marketing, packaging design, the development of enhanced sensory substitution systems, art, and man-machine interfaces. Crucially, the authors makes a convincing argument for the view that one cannot really understand touch, especially not in a real-world context, without placing it in a multisensory context. That is, the senses interact to influence tactile perception in everything - from changing the feel of a surface or product by changing the sound it makes or the fragrance it has. For students and researchers in the brain sciences, this book presents a valuable and fascinating exploration into one of our least understood senses

Download or read book Research on Ship Design and Optimization Based on Simulation Based Design SBD Technique written by Bao-Ji Zhang and published by Springer. This book was released on 2018-05-30 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ship optimization design is critical to the preliminary design of a ship. With the rapid development of computer technology, the simulation-based design (SBD) technique has been introduced into the field of ship design. Typical SBD consists of three parts: geometric reconstruction; CFD numerical simulation; and optimization. In the context of ship design, these are used to alter the shape of the ship, evaluate the objective function and to assess the hull form space respectively. As such, the SBD technique opens up new opportunities and paves the way for a new method for optimal ship design. This book discusses the problem of optimizing ship’s hulls, highlighting the key technologies of ship optimization design and presenting a series of hull-form optimization platforms. It includes several improved approaches and novel ideas with significant potential in this field
Download or read book Resolution Of The Twentieth Century Conundrum In Elastic Stability written by Isaac E Elishakoff and published by World Scientific. This book was released on 2014-05-29 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been stability theories developed for beams, plates and shells — the most significant elements in mechanical, aerospace, ocean and marine engineering. For beams and plates, the theoretical and experimental values of buckling loads are in close vicinity. However for thin shells, the experimental predictions do not conform with the theory, due to presence of small geometric imperfections that are deviations from the ideal shape.This fact has been referred to in the literature as ‘embarrassing’, ‘paradoxical’ and ‘perplexing’. Indeed, the popular adage, “In theory there is no difference between theory and practice. In practice there is”, very much applies to thin shells whose experimental buckling loads may constitute a small fraction of the theoretical prediction based on classical linear theory; because in practice, engineers use knockdown factors that are not theoretically substantiated.This book presents a uniform approach that tames this prima-donna-like and capricious behavior of structures that has been dubbed the ‘imperfection sensitivity’ — thus resolving the conundrum that has occupied the best minds of elastic stability throughout the twentieth century.
