摘要
:推广基于多极展开原理的Rayleigh方程研究具有绝缘外层的金属粒子和绝缘油所组成的理想电流变体系的力学性质 ,计算了体系的有效介电常数 .基于颗粒链模型 ,研究体系剪切应力随剪切角的变化关系 。
Rayleigh identity based on a multipole expansion theory is extended to investigatethe mechanical properties of an ideal electrorheological fluid which consists of metal particles with insulating outer layer in a dielectric oil. Evaluation of the effective dielectric constant is emphasized.The dependence of the shear stress τ on the shear strain θ and theshear modulus G for chains of particles arranged on a square lattice are presented.
