A state-of-the-art review on low-frequency nonlinear vibration isolation with electromagnetic mechanisms

Abstract Vibration isolation is one of the most efficient approaches to protecting host structures from harmful vibrations, especially in aerospace, mechanical, and architectural engineering, etc. Traditional linear vibration hard meet requirements loading capacity band simultaneously, which limits further engineering application, low-frequency range. In recent twenty years, nonlinear technology has been widely investigated broaden by exploiting beneficial nonlinearities. One studied objects “three-spring” configured quasi-zero-stiffness (QZS) isolator, can realize negative stiffness high-static-low-dynamic (HSLDS) characteristics. The with QZS overcome drawbacks achieve a better broadband performance. Due characteristics fast response, strong stroke, nonlinearities, easy control, low-cost, electromagnetic mechanisms attracted attention. this review, we focus on basic theory, design methodology, damping mechanism, active control isolators. Furthermore, provide perspectives for studies devices high-efficiency isolation.
