- Abstract:
- The damper is capable of providing a continuously variable dampering force/torque in response to a magnetic field.It consists of an upside cap and an underside cap with a rotor located between them, the magneto-rheological(MR)fluid is filled into the gaps between the rotor and the caps.When the viscosity of the MR fluid increases under the influence of the magnetic field, the movement of the rotor will be resisted.The output torque is made up of the torque caused by the magnetic field, the torque caused by the plastic viscosity of the MR fluid, and the torque caused by the coulomb friction.The viscous torque can be calculated by a simple method and the frictional torque can be obtained by experiments. The torque dependent on the magnetic field is obtained by electromagnetic finite element analysis.Experiments are done on the damper prototype and the validity of the design is verified.
- 研制了一种用于被动力/力矩再现的新型磁流变液阻尼器, 该阻尼器能够在磁场的作用下产生连续变化的阻尼力/力矩.阻尼器的结构包括一个上盖和一个下盖, 一个转子设置于上盖和下盖之间, 转子与上下盖之间的间隙充满磁流变液, 在磁场作用下其粘度变大时, 转子相对于壳体将受阻尼力作用.阻尼力矩的模型主要由以下几部分组成:一是由磁场作用于磁流变液产生的力矩, 二是由磁流变液的动力粘度产生的力矩, 最后是由装置的摩擦产生的力矩.由动力粘度产生的力矩可以通过简单的方法进行计算, 由摩擦产生的力矩可以通过实验测得, 而由磁场产生的力矩则要通过电磁场的有限元分析得到.最后, 对研制的阻尼器原型进行了性能实验, 检验了设计方法的有效性.
