Maddikunta J. Mechanical Vibrations and Noise Control 2024

Textbook in PDF format In the design and analysis of mechanical structures coupled with rotational systems, the presence of shock and vibration poses significant challenges. These problems have adverse effects on the normal functioning of these structures, resulting in reduced efficiency and compromised safety and reliability. Additionally, the vibration-induced noise generated by these systems can be a source of environmental nuisance, causing discomfort to individuals and potentially damaging the structure itself. Consequently, addressing shock and vibration-related issues becomes crucial for promoting the widespread application of such structures. One way to tackle these challenges is through the utilization of shock and vibration signals. These signals provide valuable information about the working state of the structure, enabling the identification and diagnosis of potential faults. Modal analysis, a technique used to study the dynamic characteristics of structures, is essential for controlling noise and vibration, as well as enhancing safety and stability. However, despite the importance of noise and vibration control in mechanical structures coupled with rotational systems, it remains a formidable challenge for researchers, engineers, and constructors alike. To mitigate vibrations, numerous studies have been conducted on vibration isolation, suppression, and resistance. Additionally, significant advancements have been made in the development of technologies that actively suppress vibrations. Recent reports indicate that vibrations can now be effectively suppressed with higher performance. Therefore, the control of mechanical vibration has emerged as a critical topic, prompting extensive research efforts in this field over the years. Active control of vibration is one area that has garnered considerable attention. This approach involves incorporating the ability to actuate the system in a controlled manner into the structure itself. Sensors are employed to measure the vibrations, and secondary inputs are introduced to actuate the flexible body, aiming to achieve the desired structural response. This active control methodology holds promise for effectively mitigating vibrations and enhancing the performance of mechanical structures coupled with rotational systems. The purpose of this book is to provide an overview of the most recent advances in the field of shock and vibration in mechanical structures coupled with rotational systems, with a particular emphasis on their control. By exploring these advancements, the book aims to contribute to the collective knowledge and understanding of this topic. It provides a comprehensive resource for individuals seeking to address the challenges posed by shock and vibration in mechanical structures coupled with rotational system
