| 摘 要： | 通过控制球磨时间,用球磨机球磨出不同粒径的羰基铁粉,制得单一粒径磁流变液8组和两种粒径磁流变液6组。采用旋转流变仪对磁流变液的零场粘度和剪切强度进行了测试。结果表明,在相同磁场强度下,两种粒径磁流变液的剪切强度比单一粒径磁流变液的有明显提升,提升效果与颗粒的成份密切相关,且其零场粘度和沉降稳定性与单一粒径的差别很小。

| Abstract: | Carbonyl iron powders were produced in different sizes by using ball mill and controlling the milling time,and 8 MRFs with single-sized particles and 6 MRFs with dual-sized particles were obtained.Zero-field viscosity and shear stress were tested through rotational rheometer.Test results showed that shearing stress of MRFs with dual-sized particles was enhanced comparing with MRFs with single-sized particles in the same magnetic fields.The enhanced effect was closely related to the composition of particles.... |
