摘　　要：介绍了一种新的电流变效应研究中用来计算颗粒间相互作用力的模型——偏心电偶极子模型。分析了偏心电偶极子模型的理论基础,研究了将其应用于计算电流变液体中颗粒间相互作用力的方法,并给出了用于计算相邻颗粒间作用力的公式,最后将所得结果与经典点电偶极子模型、交互点电偶极子模型及用有限元方法得出的计算结果进行了对比。结果表明:偏心电偶极子模型优于经典点电偶极子模型及交互点电偶极子模型。In this paper a new displaced dipole for calculating particles interaction force in electrorheological fluids is proposed. The theroy of displaced dipole model is analyzed and the method on calculating the pair particles attractive force in the electrorheoloigcal fluids is studied. A formula to calculate the neighor-pair attractive force is proposed. The results of attractive force of using displaced dipole method are compared with those obtained from the dipole method and finite-element analysis method, and it revealed that the displaced dipole model is better than the classic diploe model and interactive dipole model in calculating oarticles attractive force in elcetrorheological fluids.
