Flexible Multibody Dynamics comprehensively describes the numerical modelling of flexible multibody dynamics systems in space and aircraft structures, vehicles, and mechanical systems. A rigorous approach is followed to handle finite rotations in 3D, with a thorough discussion of the different alternatives for parametrization. Modelling of flexible bodies is treated following the Finite Element technique, a novel aspect in multibody systems simulation. Moreover, this book provides extensive coverage of the formulation of a general purpose software for flexible multibody dynamics analysis, based on an exhaustive treatment of large rotations and finite element modelling, and incorporating useful reference material. Features include different solution techniques such as: - time integration of differential-algebraic equations
- non-linear substructuring
- continuation methods
- nonlinear bifurcation analysis.
In essence, this is an ideal text for senior undergraduates, postgraduates and professionals in mechanical and aeronautical engineering, as well as mechanical design engineers and researchers, and engineers working in areas such as kinematics and dynamics of deployable structures, vehicle dynamics and mechanical design.
Engineering Analysis with ANSYS Software, Second Edition, provides
a comprehensive introduction to fundamental areas of engineering
analysis needed for research or commercial engineering projects.
The book introduces the principles of the finite element method,
presents an overview of ANSYS technologies, then covers key
application areas in detail. This new edition updates the latest
version of ANSYS, describes how to use FLUENT for CFD FEA, and
includes more worked examples. With detailed step-by-step
explanations and sample problems, this book develops the reader's
understanding of FEA and their ability to use ANSYS software tools
to solve a range of analysis problems.
This book summarises work done and experience gained over the past
three decades in the area of tribology in electrical environments.
It takes a close look at behaviour and response characteristics of
rolling-element, and hydrodynamic journal & thrust bearings
working under the influence of electrical current. Detailed
analysis plugs the existing knowledge gaps in the area of tribology
in electrical environments. This is because the genesis of
intermolecular forces during tribological interaction involves
electrostatic attraction or repulsion that creates electro-dynamic,
magnetic and exchange forces between atoms. Therefore all
tribological phenomena occurring in any interacting system is
electrical in nature.

Fault Diagnosis and Sustainable Control of Wind Turbines: Robust
Data-Driven and Model-Based Strategies discusses the development of
reliable and robust fault diagnosis and fault-tolerant
('sustainable') control schemes by means of data-driven and
model-based approaches. These strategies are able to cope with
unknown nonlinear systems and noisy measurements. The book also
discusses simpler solutions relying on data-driven and model-based
methodologies, which are key when on-line implementations are
considered for the proposed schemes. The book targets both
professional engineers working in industry and researchers in
academic and scientific institutions. In order to improve the
safety, reliability and efficiency of wind turbine systems, thus
avoiding expensive unplanned maintenance, the accommodation of
faults in their early occurrence is fundamental. To highlight the
potential of the proposed methods in real applications,
hardware-in-the-loop test facilities (representing realistic wind
turbine systems) are considered to analyze the digital
implementation of the designed solutions. The achieved results show
that the developed schemes are able to maintain the desired
performances, thus validating their reliability and viability in
real-time implementations. Different groups of readers-ranging from
industrial engineers wishing to gain insight into the applications'
potential of new fault diagnosis and sustainable control methods,
to the academic control community looking for new problems to
tackle-will find much to learn from this work.

Special attention is given to FOS applications in harsh
environments. Due to recent technology advances, optical fibers
have found uses in many industrial applications. Various sectors
are major targets for FOS's capable of measuring mechanical
parameters, such as pressure, stress, strain and temperature.
Opto-mechanical FOS's offer unique advantages, including immunity
to electromagnetic interference, high fidelity and signal-to-noise
ratio, low-loss remote sensing and small size.
Handbook of Thermoset-Based Biocomposites is a three-volume set
that provides a comprehensive review on the recent developments,
characterization, and applications of natural fiber-reinforced
biocomposites. An in-depth look at hybrid composites, nanofillers,
and natural fiber reinforcement is divided into three books on
polyester, vinyl ester, and epoxy composites. The volumes explore
the widespread applications of natural fiber-reinforced polyester,
vinyl ester, and epoxy composites ranging from the aerospace
sector, automotive parts, construction and building materials,
sports equipment, and household appliances. Investigating the
physio-chemical, mechanical, and thermal properties of these
composites, the volumes also consider the influence of
hybridization, fibre architecture, and fibre-ply orientation. This
three-volume set serves as a useful reference for researchers,
graduate students, and engineers in the field of composites.
The book summarizes the results of the European research project
"Intelligent fixtures for the manufacturing of low rigidity
components" (INTEFIX). The structure of the book follows the
sub-projects which are dedicated to case studies within the
scenarios "vibrations", "deformations" and "positioning". The
INTEFIX project deals with the development and analysis of several
exemplary types of intelligent, sensor and actuator integrated
fixtures for the clamping of sensitive workpieces in cutting
machine tools. Thus, the book gives a representative overview about
this innovative field of technology. The demands of the case
studies are described and the technological approaches and
solutions are introduced. Furthermore, innovative methods for the
design and optimization of intelligent fixtures are presented.
Introduction to Linear Control Systems is designed as a standard
introduction to linear control systems for all those who one way or
another deal with control systems. It can be used as a
comprehensive up-to-date textbook for a one-semester 3-credit
undergraduate course on linear control systems as the first course
on this topic at university. This includes the faculties of
electrical engineering, mechanical engineering, aerospace
engineering, chemical and petroleum engineering, industrial
engineering, civil engineering, bio-engineering, economics,
mathematics, physics, management and social sciences, etc. The book
covers foundations of linear control systems, their raison detre,
different types, modelling, representations, computations,
stability concepts, tools for time-domain and frequency-domain
analysis and synthesis, and fundamental limitations, with an
emphasis on frequency-domain methods. Every chapter includes a part
on further readings where more advanced topics and pertinent
references are introduced for further studies. The presentation is
theoretically firm, contemporary, and self-contained. Appendices
cover Laplace transform and differential equations, dynamics,
MATLAB and SIMULINK, treatise on stability concepts and tools,
treatise on Routh-Hurwitz method, random optimization techniques as
well as convex and non-convex problems, and sample midterm and
endterm exams. The book is divided to the sequel 3 parts plus
appendices. PART I: In this part of the book, chapters 1-5, we
present foundations of linear control systems. This includes: the
introduction to control systems, their raison detre, their
different types, modelling of control systems, different methods
for their representation and fundamental computations, basic
stability concepts and tools for both analysis and design, basic
time domain analysis and design details, and the root locus as a
stability analysis and synthesis tool. PART II: In this part of the
book, Chapters 6-9, we present what is generally referred to as the
frequency domain methods. This refers to the experiment of applying
a sinusoidal input to the system and studying its output. There are
basically three different methods for representation and studying
of the data of the aforementioned frequency response experiment:
these are the Nyquist plot, the Bode diagram, and the
Krohn-Manger-Nichols chart. We study these methods in details. We
learn that the output is also a sinusoid with the same frequency
but generally with different phase and magnitude. By dividing the
output by the input we obtain the so-called sinusoidal or frequency
transfer function of the system which is the same as the transfer
function when the Laplace variable s is substituted with . Finally
we use the Bode diagram for the design process. PART III: In this
part, Chapter 10, we introduce some miscellaneous advanced topics
under the theme fundamental limitations which should be included in
this undergraduate course at least in an introductory level. We
make bridges between some seemingly disparate aspects of a control
system and theoretically complement the previously studied
subjects. Appendices: The book contains seven appendices. Appendix
A is on the Laplace transform and differential equations. Appendix
B is an introduction to dynamics. Appendix C is an introduction to
MATLAB, including SIMULINK. Appendix D is a survey on stability
concepts and tools. A glossary and road map of the available
stability concepts and tests is provided which is missing even in
the research literature. Appendix E is a survey on the
Routh-Hurwitz method, also missing in the literature. Appendix F is
an introduction to random optimization techniques and convex and
non-convex problems. Finally, appendix G presents sample midterm
and endterm exams, which are class-tested several times.
This book conveys the theoretical and experimental basics of a
well-founded measurement technique in the areas of high DC, AC and
surge voltages as well as the corresponding high currents.
Additional chapters explain the acquisition of partial discharges
and the electrical measured variables. Equipment exposed to very
high voltages and currents is used for the transmission and
distribution of electrical energy. They are therefore tested for
reliability before commissioning using standardized and future test
and measurement procedures. Therefore, the book also covers
procedures for calibrating measurement systems and determining
measurement uncertainties, and the current state of measurement
technology with electro-optical and magneto-optical sensors is
discussed.
Active Disturbance Rejection Control of Dynamic Systems: A Flatness
Based Approach describes the linear control of uncertain nonlinear
systems. The net result is a practical controller design that is
simple and surprisingly robust, one that also guarantees
convergence to small neighborhoods of desired equilibria or
tracking errors that are as close to zero as desired. This
methodology differs from current robust feedback controllers
characterized by either complex matrix manipulations, complex
parameter adaptation schemes and, in other cases, induced high
frequency noises through the classical chattering phenomenon. The
approach contains many of the cornerstones, or philosophical
features, of Model Free Control and ADRC, while exploiting flatness
and GPI control in an efficient manner for linear, nonlinear,
mono-variable and multivariable systems, including those exhibiting
inputs delays. The book contains successful experimental laboratory
case studies of diverse engineering problems, especially those
relating to mechanical, electro-mechanical, robotics, mobile
robotics and power electronics systems.
Maximum Dissipation: Non-Equilibrium Thermodynamics and its
Geometric Structure explores the thermodynamics of non-equilibrium
processes in materials. The book develops a general technique
created in order to construct nonlinear evolution equations
describing non-equilibrium processes, while also developing a
geometric context for non-equilibrium thermodynamics. Solid
materials are the main focus in this volume, but the construction
is shown to also apply to fluids. This volume also: * Explains the
theory behind thermodynamically-consistent construction of
non-linear evolution equations for non-equilibrium processes *
Provides a geometric setting for non-equilibrium thermodynamics
through several standard models, which are defined as maximum
dissipation processes * Emphasizes applications to the
time-dependent modeling of soft biological tissue Maximum
Dissipation: Non-Equilibrium Thermodynamics and its Geometric
Structure will be valuable for researchers, engineers and graduate
students in non-equilibrium thermodynamics and the mathematical
modeling of material behavior.
