Preface

Decreasing the level of vibration of machines, devices, and equipment is one of the most important problems of modern engineering. Suppression of harmful vibrations contributes to the product’s normal functionality, leads to increased product reliability, and reduces the negative impact on the human operator. This is the reason why suppressing vibrations is a complicated technical issue with far-reaching implications. The set of methods and means for reducing vibrations is called vibration protection (VP). Modern objects for which VP is necessary include engineering structures, manufacturing equipment, airplanes, ships, and devices on mobile objects, to name a few. The principal approaches to VP, concepts, and methods remain the same regardless of the variations in different objects. Modern VP theory encompasses a broad scope of ideas, concepts, and methods. The theory of VP is largely based on the common fundamental laws of vibration theory, theory of structures, and control system theory and extensively uses the theory of differential equations and complex analysis. This book presents a systematic description of vibration protection problems, which are classified as passive vibration protection, parametric (invariant), and active vibration protection. Passive vibration suppression means usage of passive elements only, which
