Abstract

There are many noise and vibration phenomena in complicated mechanical and electrical systems. It is very obvious that vibration and vibration-induced noise are not desirable for normal but safe operation of such mechanical and electrical systems. Vibration and vibration-induced noise reduce the efficiency of the complicated mechanical and electrical systems and degrade the safety and comfort of the mechanical and electrical systems. Moreover, vibration-induced noise that is a common source of the environmental nuisance will discomfort people and may damage to the complicated mechanical and electrical devices. Vibration signals will also provide so ample information on the work state of the complicated mechanical and electrical systems that the work state of the complicated mechanical and electrical systems can be diagnosed. Modal, nonlinear dynamics and optimization analysis is very important to control noise and vibration and enhance the safety and the stability of the complicated mechanical and electrical systems. Noise and vibration in the complicated mechanical and electrical systems and its control still represents a serious challenge to academic researchers, industrial engineers, and engine constructors.
This special issue is dedicated to the most recent advances in the research of the noise and vibration in the complicated mechanical and electrical systems and its control. We invited global scientists, researchers and industrial investigators to contribute original research and review articles, which address the topics of the special issue. We received more than 40 manuscripts from a number of different countries. After professional review by the guest editors, Prof. Jiaqiang E from Hunan University, China and associate editor, Prof. Dan Zhao from University of Canterbury, New Zealand and dedicated reviewers, 18 manuscripts are finally accepted and published on the journal of Low Frequency Noise Vibration and Active Control.
This issue could not have been done without the contribution and the dedication of the co-editor, Prof. Jiaqiang E and the contributing authors. They have spent many hours from their busy schedules on research, writing, and editing the articles. Likewise, the professional and anonymous reviewers contributed dramatically their time on reviewing, commenting, and improving the articles. The support and encouragement of Prof. M. Osman Tokhi, the editor-in-chief of the journal of Low frequency Noise, Vibration and Active Control and Ms. Clare Legge are greatly appreciated.
