一种磁流变液制动演示装置的磁路设计

摘要

设计了一种磁流变液制动演示装置，为了使磁流变液在匀强磁场下工作，采用多层密绕螺线管的方式产生磁场，并对螺线管所用铜线的规格和缠绕的匝数进行选择和计算，这种方式使得在通入相同的电流时能产生更大的磁场。最后，应用MATLAB软件对励磁线圈所产生的磁场的分布与大小进行仿真，结合磁场的实际测量数据对比分析，证明外加磁场符合演示实验要求，能够达到理想的演示目的。%Designed a MRF brake demonstration device, in order to make the magnetorheological fluid well work under uniform magnetic field,the way of multi-layer tightly wound solenoid was used to produce magnetic field,while the specification of solenoid’ s copper wire was selected and coil number was calculated. This way can produce a stronger magnetic field when going into the same current.Finally,the MATLAB software was ap-plied to simulate the distribution and size of the magnetic field generated by the coil.Combining theoretical val-ue and the actual measurement data of the to compare and analysis,the magnetic field was proved to be up to the mustard,the device can carry ideal demonstration point.
