Characterization of an Electromagnetic Vibration Isolator

Abstract

A novel vibration isolator is constructed by connecting a mechanical spring in parallel with a magnetic spring in order to achieve the property of high-static-low-dynamic stiffness (HSLDS

Structural vibration absorption in multilayered sandwich structures using negative stiffness nonlinear oscillators

“…Tunable [52] electromagnet NSMs could be realized by replacing some magnet components with electromagnets. Zhou and Liu [53,54] constructed an electromagnet NSM in which a center permanent magnet was placed between a pair of electromagnets. Pu et al [55] proposed negative stiffness springs with coils and coaxial magnets.…”
