【摘要】 磁流变传动装置引入磁流变液作为工作介质,利用磁流变液的屈服剪切应力来传递转矩。基于Bingham模型和磁性物理理论,对磁流变传动装置的工作机理进行了探讨,分析了磁流变液中磁性颗粒的链化模型,给出了磁流变传动装置传递转矩计算公式,并通过理论分析和实验验证对磁流变传动装置传动性能及其影响因素进行了讨论。研究结果表明,磁流变液的磁致屈服应力在转矩传递中起主导作用,磁流变传动装置能传递较大转矩,具有良好的恒转矩特性。更多还原

【Abstract】 Based on the Bingham model and the magnetic physics theory,the working principle of the MR transmission device(MRTD) was studied,the chain model in magnetorheological fluid(MRF) was analyzed,the influence of viscous resistance and centrifugal force for the transmission torque was given,and some properties as well as influencing factors of MRTD were discussed by means of theoretical analysis and experiments.The study results show that a big torque can be transmitted and the MRTD has a good constant-torque characteristic.更多还原
