Title   Magneto Circuit Design of Adaptive Magnetorheological  Structure and Methods of Testing its Properties       

Abstract

Magnetorheological elastomer (MRE) is a new kind of intelligent material whose elastic modulus can be changed with the magnetic field. It has a broad prospect of applications for the wide-frequency and small-amplitude vibration isolation. The adaptive magnetorheological structure is a vibration isolation equipment which is made up of magnetorheological elastomer, magnetic conductor, excitation coil and field spool. Its stiffness can be altered in real time according to the external environment. For the successful application of adaptive magnetorheological structure, to design magnetic circuit with excellent performance is the first problem to solve. According to theorems of the magnetic circuit, the design method of magnetic circuit of the adaptive magnetorheological structure is introducted in detail, and the dimensions of the adaptive magnetorheological structure are designed in this paper. The magnetic circuit of the adaptive magnetorheological structure is calculated by the finite element method using the electromagnetic module of ANSYS software, then the test on performance of the magnetic circuit is conducted. Theoretical analysis, software simulation and experimental test are used to verify the rationality of the design of the adaptive magnetorheological structure.
