Mechanical Vibration and Shock Analysis, Volume 3, Random Vibration

Beschreibung

Mechanical Vibration and Shock Analysis, Second Edition Volume 3: Random Vibration The vast majority of vibrations encountered in a real-worldenvironment are random in nature. Such vibrations are intrinsicallycomplicated, but this volume describes a process enabling thesimplification of the analysis required, and the analysis of thesignal in the frequency domain. Power spectrum density is alsodefined, with the requisite precautions to be taken in itscalculation described together with the processes (windowing,overlapping) necessary for improved results. A furthercomplementary method, the analysis of statistical properties of thetime signal, is described. This enables the distribution law of themaxima of a random Gaussian signal to be determined and simplifiescalculation of fatigue damage to be made by the avoidance of thedirect counting of peaks. The Mechanical Vibration and Shock Analysis five-volumeseries has been written with both the professional engineer and theacademic in mind. Christian Lalanne explores every aspect ofvibration and shock, two fundamental and extremely significantareas of mechanical engineering, from both a theoretical andpractical point of view. The five volumes cover all the necessaryissues in this area of mechanical engineering. The theoreticalanalyses are placed in the context of both the real world and thelaboratory, which is essential for the development ofspecifications.
