Available in PDF, EPUB and Kindle. Book excerpt: The basic components of electromechanical actuators include geartrains, prime movers, bearings, shafts, sensors, cooling components, and fasteners. A common requirement that drives a typical actuator design process is providing the output torque and speed needed for the given actuator task in a minimum volume/weight geometry. Two important questions to be answered in this research relate to the scaling and configuration management of an electromechanical actuator design. The first question is: "Given an electromechanical actuator design, how can it be scaled to produce another design that meets a different set of requirements (e.g., torque, speed, weight, life)?" The second question is: "Given an electromechanical actuator design, how can a designer change the configuration to obtain another design that meets the same set of requirements in a different geometric package/shape?" The answers to these questions rely on the development of a science of design process for electromechanical actuators to replace the current design process, which is based primarily on designer experience and often requires multiple design iterations. The Robotics Research Group (RRG) is currently working on this science of design process, which includes parametric design rules that can be used to reveal how actuator design parameters affect its key performance indicators. To improve this science, this research develops a detailed parametric model of the primary actuator components for a standard actuator, summarizes the design rules available from this model, formally defines the concepts of scaling and configuration management, and lays out a step-by-step process to implement these concepts. The parametric model used in this research builds on the existing models of previous RRG researchers. The design rules are developed based on the fundamental modeling equations that govern the design of the actuator components. The concepts of scaling and configuration management are defined as two of the fundamental design operations that can be applied to an electromechanical actuator. A scaling and configuration management process, which requires the parametric model, is developed and applied to an existing set of baseline actuator designs. The result of this process is the creation of actuator designs of intermediate size between the sizes of existing actuators, which makes it suitable for populating an actuator family. To handle the size and complexity of the actuator parametric model, this research introduces the model reduction technique of monotonicity analysis and illustrates how it is well suited for the electromechanical actuator design problem. A future goal of the RRG is to create a software tool that will contain a complete actuator parametric model, component design rules (of this and future research), and scaling and configuration management options, which will allow users to design actuators with a minimum amount of time, cost, and knowledge

Download or read book The Design of a Hingeline Electro mechanical Actuator written by Kevin Stuart Kendrick and published by . This book was released on 2006 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft control mechanisms, such as those that operate the flaps, ailerons, rudders, etc., are almost exclusively driven by hydraulic-based systems. Their popularity in flight control systems is not unfounded; hydraulic actuators are quite torque-dense and benefit from decades of development bringing operating performance to a high level. On the other hand the infrastructure to support this system increases weight, adds system development complexity, and reduces aircraft maintainability [Jensen et al, 2000]. Based on recent Electro-Mechanical Actuator (EMA) development and design efforts at the Robotics Research Group (RRG), a new opportunity exists to replace current hydraulic flight control systems with those powered by electricity through a national program [Tesar, 2005]. A literature review of the topic found a 30 year old effort by AiResearch to develop a similarly powered hingeline actuator with given traditional performance goals (torque capacity, redundancy, output speed, reliability). In this report,a thorough analysis is performed on each major component group to quantitatively evaluate this baseline device. Using component technologies developed at RRG, this report proposes a dual torque-summing electromechanical actuator, each with a star compound / hypocyclic combined gear train, designed to exceed the performance of the original (1976) AiResearch project. This preliminary design exercise includes a layout of the entire actuator along with an appropriate analysis of major components including bearings, gear train, motor, housing, and release mechanism. The performance of this gear train is critical to overall actuator success and fundamental analytics have already been developed in this area [Park and Tesar, 2005]. Finite Element Analysis on the gear train and housing provide early design feedback and verification of actuator performance characteristics. In particular, simulation results show the gear stiffness, load sharing, and torque capacities exceed analytical estimates. Finally, four different comparisons are presented that evaluate configuration variations of the two designs based on applicable performance criteria. Results show the RRG fault-tolerant actuator has a marked improvement over the baseline in average stiffness (14.2x), reflected inertia (3.2x) and nominal torque density (3.4x). The chapter next lists actuator test methods and aircraft qualification standards. Finally, a summary of future work is detailed in a ten step outline to bring this EMA technology to a level of early deployment in a large range of aircraft systems.

This book was released on 2012-09-26 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite achievements in the application of enzymes, antibodies and biological receptors to diagnostics and sensing, the last two decades have also witnessed the emergence of a number of alternative technologies based on synthetic chemistry. This volume shows how synthetic receptors can be designed with characteristics that make them attractive alternatives to biological molecules in the sensory and diagnostics fields, with contributions from leading experts in the area. Subjects covered include synthetic receptors for a range of biomolecules, the use of antimicrobial peptides for the detection of pathogenic microorganisms, the development of molecularly imprinted polymer (MIP) nanoparticles, the in silico design of MIPs and MIP-based sensors, and two chapters examining the development of sensors from an industrial point of view. The particular focus of all chapters is on practical aspects, either in the development process or the applications of the synthesized materials. This book will serve as an important reference work for business leaders and technology experts in the sensors and diagnostics sector.

Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Intelligent Vehicles provides a complete coverage of the fundamentals, new technologies, and sub-areas essential to the development of intelligent vehicles; it also includes advances made to date, challenges, and future trends. Significant strides in the field have been made to date; however, so far there has been no single book or volume which captures these advances in a comprehensive format, addressing all essential components and subspecialties of intelligent vehicles, as this book does. Since the intended users are engineering practitioners, as well as researchers and graduate students, the book chapters do not only cover fundamentals, methods, and algorithms but also include how software/hardware are implemented, and demonstrate the advances along with their present challenges. Research at both component and systems levels are required to advance the functionality of intelligent vehicles. This volume covers both of these aspects in addition to the fundamentals listed above.
