Building on the success of Modeling, Analysis, and Control of Dynamic Systems, 2/e, William Palm's new book offers a concise introduction to vibrations theory and applications. This text is intended to be an introduction to the subject of mechanical vibrations, for courses typically offered in the junior or senior year in mechanical engineering, aerospace engineering, or engineering mechanics curricula. Common applications of the subject are vehicle suspension systems and vibration isolators and absorbers designed to minimize the effects of vibration on people and machines. The subject is based on dynamics and applied differential equations. These topics, normally covered in prerequisite courses, are reviewed in the text.
