<DIV>Friction-vibration interactions are common but important phenomena in science and engineering. The author, Gang Sheng Chen, introduces the principles and provides the resources to understand and work with these interactions. The first three chapters introduce basic concepts and analytical methods of friction and vibration, while chapter four presents the general principles on friction-vibration interactions, and also touches on various engineering applications. The conclusion extends the concepts and methods to some of the most critical engineering applications in high-tech industry, presenting the friction-vibration interaction principle and applications in data storage systems.</div>
