针对磁流变液的静置沉降和磁流变弹性体控制范围小的问题,以六甲基二硅氧烷和聚二苯基硅氧烷的反应物作为磁流变材料的载体,加入特殊的添加剂,采用球磨分散方法,研制出了4种不同组分磁流变粘弹性流体(MRVF)样品。采用奥地利安东帕高级旋转流变仪(MCR-301)对上述样品进行了流变学性能测试。实验表明在剪切率为200s-1,磁感应强度为0~0.9T条件下,剪切应力的调节范围为5~120kPa；根据剪切应力与剪切率的关系曲线,采用高斯函数描述其本构模型,并运用最小二乘法辨识其模型参数；在25~80℃温度范围内测试了磁流变粘弹性流体的温度衰减特性,其剪切应力衰减不超过10%；经3个月静置观察,磁流变粘弹性流体的沉降率低于4%。
In order to overcome the particle sedimentation issue of MRF,along with the small control range trou-ble of MRE,a new MR material,named as magneto-rheological viscoelastic fluid (MRVF),was put forward. The carrier of MRVF was based on the chemical products of hexamethyldisiloxane and polyborodiphenylsilox-ane.By means of ball milling method and special additives,four samples are developed.The rotary rheometer, Austrian Anton Par MCR-301,was used to test the rheological properties of the samples.The experimental re-sults show that the shear stress varies from 5 to 120kPa with the shear rate of 200s-1 and magnetic induction in-tensity of 0-0.9T.According to the curves of shear stress versus shear rate,Gaussian Function was adopted to describe the constitutive model,and the least square method was applied to identify the parameters of the mod-el.The shear stress decreases less than 10% with temperature increasing from 25 to 80℃.After standing for three months,the sedimentation rate of the samples was less than 4%.
