Friction-Induced Vibration in Lead Screw Drives covers the dynamics of lead screw drives with an emphasis on the role of friction. Friction-induced vibration in lead screws can be the cause of unacceptably high levels of audible noise as well as loss of operation accuracy and shortened life. Although lead screw drives have a long history and their mechanical design and manufacturing aspects are very well understood, the role of friction in their dynamical behavior has not been comprehensively treated. The book draws on the vast body of work on the subject of dynamical systems with friction (such as disk brake systems) and offers said treatment, along with: · Unique coverage of modeling of multi-DOF lead screw systems with friction · Detailed analysis of negative damping, mode coupling, and kinematic constraint instability mechanisms in lead screws drives · A practical parameter identification approach for the velocity dependent coefficient of friction in lead screw drives Friction-Induced Vibration in Lead Screw Drives serves as the definitive text on the friction-induced vibration of lead screws, and includes a practical case study where the developed methods are used to study the excessive noise problem of a lead screw drive system and to put forward design modifications that eliminate the friction-induced vibrations.

The impact of friction-induced vibrations varies industry by industry. In the automotive industry, it affects the reliability and quality of mechanical components. For magnetic hard drives, it can affect stability. Over the last two decades, much research has been dedicated to addressing this critical area, and while the results have been significant, until now, this research has remained scattered throughout the literature. A Unified Framework: Both Elegant and Applicable Bringing together recent research and advances from several industries, Friction-Induced Vibrations and Sound presents a unified theoretical framework that engineers and researchers will find immediately applicable. Drawing on his in-depth experience in the data storage, electronics, and automotive industries, as well as his involvement with academic research, Gang Sheng presents a complete survey of this interdisciplinary subject. In the first chapters he offers a theoretical basis for friction induced vibrations. He explains the underlying principles, while also delving into methods for analyzing vibration and sound at the nano-, micro-,and macroscale levels. Sheng reinforces these concepts by taking a thoughtful look at friction-induced vibrations and sound in nature and everyday life. The latter chapters examine critical engineering applications in the data storage and automotive industries. Here Sheng illustrates the impact of advances in modeling and experimental analysis. He elaborates with detailed coverage of acoustic emission techniques used in computer hard disk drive systems, as well as noise control in automotive belt drive and brake systems. As the first comprehensive resource of its kind, this volume provides a grounding that will allow those in industry to address their specific challenges with vibration and sound. It also provides the stimulation and a starting point for those researchers looking to develop new solutions to problems that persist in the field.
