Modeling of dynamic characteristics of a nonlinear oscillatory system with a magnetic spring. Part 1

Abstract

A passive magnetic vibration isolator (a magnetic spring) with cylindrical magnets is considered. A mathematical model is developed to calculate magnetic spring magnetic field and force. Numerical calculation of the vibration isolator magnetic field via a 3-D finite element method is performed. Experimental results presented prove adequacy of the computational data.
