Ingenieria industrial

This book is written as an introduction to rotor-bearing dynamics for practicing engineers and students who are involved in rotordynamics and bearing design. The goal of this book is to provide a step-by-step approach to the understanding of fundamentals of rotor-bearing dynamics by using DyRoBeS . Therefore, the emphasis of this book is on the basic principals, phenomena, modeling, and interpretation of the results. Numerous examples, from a single-degree-of-freedom system to complicated industrial rotating machinery, are employed throughout this book to illustrate these fundamental dynamic behaviors. The concepts in the text are reinforced by parametric studies and numerous illustrative examples and figures.The book begins with a brief discussion of the mathematical modeling of physical dynamic systems and an overview of the basic vibration concepts in Chapter 1.The coordinate systems and the kinematics of the rotor motion are presented in Chapter 2.A simple two-degrees-of-freedom rotor system, the Laval-Jeffcott rotor model, is utilized in Chapter 3 to demonstrate many important phenomena in rotordynamics. This simple 2DOF model provides many valuable physical insights into more practical and complicated systems.Chapter 4 discusses the rotating disk equations and rigid rotor dynamics.Chapter 5 covers the finite element formulation for a rotating shaft element.Chapter 6 deals with various types of bearings, dampers, seals and other interconnection components. All the reaction forces from these components are non-linear in nature. The concept of linearization around the static equilibrium is discussed.Chapter 7 summarizes the lateral vibration study with several practical examples. Various solution techniques and interpretation of the results are discussed.Chapter 8 is devoted to the important subject of torsional vibration. Finally, a brief description of the balancing method, influence coefficient method is presented in Chapter 9.

This book studies methods for a robust design of rotors against self-excited vibrations. The occurrence of self-excited vibrations in engineering applications if often unwanted and in many cases difficult to model. Thinking of complex systems such as machines with many components and mechanical contacts, it is important to have guidelines for design so that the functionality is robust against small imperfections. This book discusses the question on how to design a structure such that unwanted self-excited vibrations do not occur. It shows theoretically and practically that the old design rule to avoid multiple eigenvalues points toward the right direction and have optimized structures accordingly.This extends results for the well-known flutter problem in which equations of motion with constant coefficients occur to the case of a linear conservative system with arbitrary time periodic perturbations.

This book highlights and explains the significance of philosophical, logical, and scientific principles for engineering education/training and engineering works.In so doing, it aims to help to rectify the neglect of philosophy and logic in current education and training programs, which emphasize analytical and numerical methods at the expense of the innovative practical and creative abilities so important for engineering in the past. Individual chapters examine the relation of philosophy, logic, and science to engineering, drawing attention to, for example, the significance of ethics, the relevance of the philosophy of science, and the increasing importance of application of fuzzy logic to engineering.Modeling principles and philosophy in engineering are discussed, and the impact of different education systems, examined. Too often engineers have become reliant on readily available formulations and software; this book offers an antidote, promoting the recognition of artistic and humanitarian aspects and their integration in engineering works.

In many plants, vibration and noise problems occur due to fluid flow, which can greatly disrupt smooth plant operations. These flow-related phenomena are called flow-induced vibration.This book explains how and why such vibrations happen and provides hints and tips on how to avoid them in future plant design.The world-leading author team doesnt assume prior knowledge of mathematical methods and provides the reader with information on the basics of modeling.The book includes several practical examples and thorough explanations of the structure, the evaluation method and the mechanisms to aid understanding of flow-induced vibrations.

Mechanical vibration is normally an undesired condition which can cause problems such as discomfort, noise, fatigue, etc.Shock is a particular type of vibration of transient nature containing high levels of energy in a very short period of time It is vital for engineers to understand and apply vibration control methods, either by introducing structural modifications, reducing the source of vibration, or interposing an isolator between receiver and source. The easiest mathematical representation of these isolators is a passive combination of a spring and a damping of fixed properties.There are some isolators where the properties can change depending upon the vibration source called semi active, or adaptive vibration isolators.This book explores the application of a novel stiffness switching strategy to achieve an improved shock isolator. This is a two stage strategy controlling the vibration response during the shock and the later residual vibration.The book presents a review of the state of the art in shock isolation, theoretical models for switching stiffness and experimental validation.

Javier Manterola Armisén es uno de los ingenieros más destacados y brillantes del panorama actual. Suyos son los proyectos de algunas de las obras públicas más importantes de España, como el puente sobre el Embalse de Barrios de Luna o el puente de la Bahia de Cadiz, recien finalizado. Ademas, como catedratico de puentes de la Escuela de Ingenieros de Caminos de Madrid durante mas de treinta años, ha moldeado a toda una generacion de ingenieros que no solo han recibido de el una exquisita formacion tecnica sino tambien una vision humanistica y estetica fundamentales. Manterola ha pasado toda su vida tendiendo puentes, y no solo en sentido literal. Autor de diversos ensayos y miembro de la Real Academia de Bellas Artes de San Fernando, Manterola ha dedicado buena parte de su tiempo a promover la necesidad de una apreciacion estetica y formal de las obras de ingenieria, alejandose de esa consideracion trasnochada del ingeniero como un mero solucionador de problemas tecnicos.En este documental en DVD y en el libro que lo acompaña, Manterola reflexiona sobre la tarea del ingeniero y su relacion con la arquitectura y con el entorno, al tiempo que repasa los grandes hitos de su trayectoria profesional y explica todo lo que un lego debe saber sobre puentes. Y lo hace con humildad, sencillez, sentido del humor y, de cu...
