摘　　要：由于磁流变液的应用前景广阔,而市场上磁流变液性能测试系统相对短缺,为了更好地促进磁流变液的工程应用,有必要研究磁流变液的性能测试仪。通过理论计算和实验验证的方法,设计了一种磁流变旋转式测试仪,用实测的办法验证了磁场理论计算的正确性。测试表明,当电流为1.6A时磁场达到0.5582T,MRF4的剪切应力达到70.12KPa,当电流为1.4A,磁场为0.5483T,剪切屈服强度51.6KPa。Based on he broad application of magnetorheological fluid（MRF）and the shortage of testing device of magnetorheological fluid in the market,testing device of magnetorheological fluid is designed and built necessarily to promote the application of MRF.According to theoretic calculation and practical testing,rotary testing device of MRF was designed,and the correctness of magnetic field was verified by experiment.Results showed,when current was 1.6A and magnetic induction was 0.5582T,the shear stress of MRF4 reached to 70.12 KPa;current was 1.4A and magnetic induction was 0.5483T,shear yield stress of MRF4 is 51.6 KPa.
