Abstract:
Taking account of the interaction among limited-distance neighbord chains, the effect of the shape osuspension particle in electrorheological (ER) fluid on the ground state structure of ER solid is discussed. The results of computation show that the ground state structure will change with the shape of suspension particle. Specially for flat ellipsoid particles suspended in a liquid the variation-value of interaction energy of the structure o ER solid changes in the range of 0.1~100.

摘要:
采用近邻相互作用近似方法,计算了电流变液中悬浮粒子的形状对电流变液呈固态时基本结构的影响.结果表明:基本结构将随着悬浮粒子形状的变化而变化,特别是在扁椭球情况下,固态结构的相互作用能出现几个数量级的变化.
