添加剂对TiO2电流变液性能的影响

研究不同添加剂对电流变液流变性能的影响，以提高ER液体的电流变活性。对含有不同添加剂的电流变液体进行了电流变性能测试。结果表明：几种添加剂对改善电流变液体的性能均有很好的促进作用。在4kV／mm的电场强度下，含不同添加剂的电流变液体的剪切应力分别提高12％、26％和33％。且ER液体的抗沉淀稳定性明显提高。说明适宜、适量的添加剂能有效地提高ER液体的性能。

Additive in Titania Electrorheological Fluid

This thesis studies the influences of additives on shear stress of electrorheologial fluid(ER fluid) in order to improve performance of ER fluid. ER fluid contains additives, and it is organic carboxylic acid(T1) or fatty acid and many entity mellow fat(T2,T3) .Then we test it. The result shows that all of the additives improve the performance of ER fluid. When the electric field is strengthened to 4 kV/mm under the condition that the content of additive is 3 percent, the shear stress of the ER fluid with different additive is improved in the rate of 12%,26%,33% respectively. The result also demonstrates that T1 contributes to a considerable increase in the stability of ER fluid. It is concluded that there will be a significant improvement in the property of ER fluid by dispersing appropriate type and a mount of additive to a certain ER fluid.
