Everything engineers need to know about mechanical vibration and shock...in one authoritative reference work! This fully updated and revised 3rd edition addresses the entire field of mechanical vibration and shock as one of the most important types of load and stress applied to structures, machines and components in the real world. Examples include everything from the regular and predictable loads applied to turbines, motors or helicopters by the spinning of their constituent parts to the ability of buildings to withstand damage from wind loads or explosions, and the need for cars to maintain structural integrity in the event of a crash. There are detailed examinations of underlying theory, models developed for specific applications, performance of materials under test conditions and in real-world settings, and case studies and discussions of how the relationships between these affect design for actual products. Invaluable to engineers specializing in mechanical, aeronautical, civil, electrical and transportation engineering, this reference work, in five volumes is a crucial resource for the solution of shock and vibration problems. The relative and absolute response of a mechanical system with a single degree of freedom is considered for an arbitrary excitation, and its transfer function is defined in various forms. The characteristics of sinusoidal vibration are examined in the context both of the real world and of laboratory tests, and for both transient and steady state response of the one-degree-of-freedom system. Viscous damping and then non-linear damping are considered. The various types of swept sine perturbations and their properties are described and, for the one-degree-of-freedom system, the consequence of an inappropriate choice of sweep rate are considered. From the latter, rules governing the choice of suitable sweep rates are then developed.

Mechanical Vibration and Shock Analysis, Second Edition Volume 4: Fatigue Damage Fatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also employed for a specification representing the effects produced by the set of vibrations imposed in a real-world environment. In this volume, which is devoted to the calculation of fatigue damage, the author explores the various hypotheses and models used to describe the behavior of material suffering fatigue and the laws of fatigue accumulation. He also considers the methods of counting response peaks, which are used to establish a histogram when it is impossible to use the probability density of the peaks obtained with a Gaussian signal. The expressions for mean damage and its standard deviation are established and other hypotheses are tested. The Mechanical Vibration and Shock Analysis five-volume series has been written with both the professional engineer and the academic in mind. Christian Lalanne explores every aspect of vibration and shock, two fundamental and extremely significant areas of mechanical engineering, from both a theoretical and practical point of view. The five volumes cover all the necessary issues in this area of mechanical engineering. The theoretical analyses are placed in the context of both the real world and the laboratory, which is essential for the development of specifications.

Mechanical Vibration and Shock Analysis, Second Edition Volume 3: Random Vibration The vast majority of vibrations encountered in a real-world environment are random in nature. Such vibrations are intrinsically complicated, but this volume describes a process enabling the simplification of the analysis required, and the analysis of the signal in the frequency domain. Power spectrum density is also defined, with the requisite precautions to be taken in its calculation described together with the processes (windowing, overlapping) necessary for improved results. A further complementary method, the analysis of statistical properties of the time signal, is described. This enables the distribution law of the maxima of a random Gaussian signal to be determined and simplifies calculation of fatigue damage to be made by the avoidance of the direct counting of peaks. The Mechanical Vibration and Shock Analysis five-volume series has been written with both the professional engineer and the academic in mind.

Mechanical Vibration and Shock Analysis, Second Edition Volume 2: Mechanical Shock This volume considers the shock response spectrum, its various definitions, its properties, and the assumptions involved in its calculation. In developing the practical application of these concepts, the shock shapes or profiles most often used in test facilities are presented, together with their characteristics and indications of how to establish test configurations comparable with those of the real-world, measured environment. Following this analysis there is a case study of how to meet these specifications using standard laboratory equipment, shock machines, electrodynamic exciters driven by a time signal or a response spectrum. Discussion of the limitations, advantages and disadvantages of each method is presented.

This volume focuses on specification development in accordance with the principle of tailoring. Extreme response and the fatigue damage spectra are defined for each type of stress (sinusoidal vibration, swept sine, shock, random vibration, etc.). The process for establishing a specification from the life cycle profile of equipment which will be subject to these types of stresses is then detailed. The analysis takes into account the uncertainty factor, designed to cover uncertainties related to the real-world environment and mechanical strength, and the test factor, which takes account of the number of tests performed to demonstrate the resistance of the equipment.

Die amerikanische Ausgabe dieses Buches erschien 1947 in der dritten, nicht unwesentlich erweiterten Auflage. Der Verfasser erwähnt in seinem Vorwort, daß es ursprünglich aus dem Text von Vorlesungen an der Design School der W estinghouse Company entstand und zu nächst für den Unterrichtsgebrauch an der Harvard Engineering School herausgegeben wurde. In die Neuauflage wurden neue Veröffentlichungen und eigene Erfahrungen eingearbeitet. Im Vorwort der deutschen Erstauflage (1936) wurde darauf hin gewiesen, daß das vorliegende Buch eine glückliche, dem ingenieur mäßigen Denken entsprechende Anschaulichkeit hat. Der Verfasser ver meidet es, lediglich Gebrauchsanweisungen für Rechenvorschriften zu geben; andererseits verzichtet er auf die Ausarbeitung der vollstän digen, strengen Theorie. Er versteht es, dem Leser die wesentlichen Zusammenhänge auch verwickelter Erscheinungen plausibel zu machen. So vermittelt die Darstellung nicht einen höheren theoreti schen Überblick, sondern leitet den Leser mit einfacher mathematischer oder anschaulicher mechanischer Begründung auf einen Weg, der in praktischen Schwingungsfragen zur zahlenmäßigen Lösung, mindestens aber zu einer guten Annäherung der "exakten" Lösung führt. Eine Fülle von Beispielen und Aufgaben regt dazu an, die Beherrschung der dargelegten Rechenverfahren zu erproben und zu vertiefen. Aus diesen Gründen erfolgte die Übersetzung in die deutsche Sprache. Inzwischen ist die amerikanische Ausgabe mit großem Erfolg im Hochschulunterricht eingesetzt worden. Den deutschen Leser inter essiert vielleicht der Hinweis, daß der Hochschulunterricht in Amerika von der europäischen Art sehr verschieden ist. Die Vorlesungen werden nach einem bestimmten "Textbuch" gelesen.
