A new generalized yield stress scaling equation for electrorheological (ER) fluids was developed by introducing the critical electric field (Ec) and material parameter. This equation can be used to describe the dependency of the yield stress on an electric field not only for conventional ER suspensions with a change in slope from 2.0 to 1.5, but also for giant ER fluids with a change in slope from 2.0 to 1.0. The yield stress data obtained from different ER fluid systems with different material parameters was collapsed onto a single curve for the entire range of electric field strengths using the proper scaling method proposed in this study.
通过引入临界电场 (Ec) 和材料参数，为电流变 (ER) 流体开发了一个新的广义屈服应力标度方程。该方程可用于描述屈服应力对电场的依赖性，不仅适用于斜率从 2.0 变为 1.5 的传统 ER 悬浮液，也适用于斜率从 2.0 变为 1.0 的巨型 ER 流体。使用本研究中提出的适当标度方法，将具有不同材料参数的不同 ER 流体系统获得的屈服应力数据在整个电场强度范围内合并到单个曲线上。
