Download or read book Advanced Autonomous Vehicle Design for Severe Environments written by V.V. Vantsevich and published by IOS Press. This book was released on 2015-10-20 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical vehicle dynamics, which is the basis for manned ground vehicle design, has exhausted its potential for providing novel design concepts to a large degree. At the same time, unmanned ground vehicle (UGV) dynamics is still in its infancy and is currently being developed using general analytical dynamics principles with very little input from actual vehicle dynamics theory. This technical book presents outcomes from the NATO Advanced Study Institute (ASI) ‘Advanced Autonomous Vehicle Design for Severe Environments’, held in Coventry, UK, in July 2014. The ASI provided a platform for world class professionals to meet and discuss leading-edge research, engineering accomplishments and future trends in manned and unmanned ground vehicle dynamics, terrain mobility and energy efficiency. The outcomes of this collective effort serve as an analytical foundation for autonomous vehicle design. Topics covered include: historical aspects, pivotal accomplishments and the analysis of future trends in on- and off-road manned and unmanned vehicle dynamics; terramechanics, soil dynamic characteristics, uncertainties and stochastic characteristics of vehicle-environment interaction for agile vehicle dynamics modeling; new methods and techniques in on-line control and learning for vehicle autonomy; fundamentals of agility and severe environments; mechatronics and cyber-physics issues of agile vehicle dynamics to design for control, energy harvesting and cyber security; and case studies of agile and inverse vehicle dynamics and vehicle systems design, including optimisation of suspension and driveline systems. The book targets graduate students, who desire to advance further in leading-edge vehicle dynamics topics in manned and unmanned ground vehicles, PhD students continuing their research work and building advanced curricula in academia and industry, and researchers in government agencies and private companies.

Download or read book Terrain Mechanics and Modeling Research Program Enhanced Vehicle Dynamics Module written by and published by . This book was released on 2009 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vehicle dynamics module (VEHDYN 4.0) includes many enhancements to the previously documented and released VEHDYN II model and the internally developed, but not released, VEHDYN 3.0 model. The VEHDYN 3.0 model accepted the vehicle in a settled, or equilibrium, configuration instead of the "zero-force" configuration (the force acting on each suspension spring is assumed to be zero) required by VEHDYN II. VEHDYN 3.0 also included a special suspension and a band track model that were required to model the Caterpillar 30/30 engineering vehicle. VEHDYN 3.0 was further enhanced to add several other effects including: (1) a vehicle underside interference model that computes the normal and drag forces that occur when the underside of a vehicle's sprung mass comes in contact with the terrain profile, (2) a wheel damping model which computes an additional normal force component to represent the wheel's resistance to change, (3) a vehicle-terrain interface model to allow the terrain to deform, (4) accelerating and decelerating the vehicle using tractive force-speed relations and the soil-slope resistance, (5) rotational springs for enhanced suspension beam modeling, (6) a water-vehicle buoyancy and drag model to be used when a vehicle crosses a water-filled terrain obstacle, (7) numerous new run-type options including multi-run ride and shock performance sequences, slope climbing, obstacle crossing, etc., and (8) new post processors for animation. This report documents the VEHDYN 4.0 program, including the new enhancements, the input and output files and 12 example problems.

Available in PDF, EPUB and Kindle. Book excerpt: This paper examines recent developments in modeling and simulation products formulated for use in soldier-in-the-loop laboratories utilizing motion base simulators. New, real-time, ground platform mobility and terrain models have been demonstrated that show vehicle mobility interactions in soft soils. Laboratory data collections have been vastly improved via the incorporation of a new product called SimObserver(TradeMark) The paper also provides example experiment results recently performed to quantify soldier performance in moving vehicle environments. The new products and results help evaluate manned and unmanned ground platform concepts and technologies. Most of these new technology products have been developed by partnerships with the Ground Vehicle Simulation Laboratory located at the Tank-Automotive Research Development Engineering Center (TARDEC) in Warren, Michigan.

Available in PDF, EPUB and Kindle. Book excerpt: The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory

Download or read book Application of Lightweighting Technology to Military Aircraft Vessels and Vehicles written by National Research Council and published by National Academies Press. This book was released on 2012-04-27 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lightweighting is a concept well known to structural designers and engineers in all applications areas, from laptops to bicycles to automobiles to buildings and airplanes. Reducing the weight of structures can provide many advantages, including increased energy efficiency, better design, improved usability, and better coupling with new, multifunctional features. While lightweighting is a challenge in commercial structures, the special demands of military vehicles for survivability, maneuverability and transportability significantly stress the already complex process. Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft assesses the current state of lightweighting implementation in land, sea, and air vehicles and recommends ways to improve the use of lightweight materials and solutions. This book considers both lightweight materials and lightweight design; the availability of lightweight materials from domestic manufacturers; and the performance of lightweight materials and their manufacturing technologies. It also considers the "trade space"-that is, the effect that use of lightweight materials or technologies can have on the performance and function of all vehicle systems and components. This book also discusses manufacturing capabilities and affordable manufacturing technology to facilitate lightweighting. Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft will be of interest to the military, manufacturers and designers of military equipment, and decision makers.
