摘要
提出了一种温控变面磁流变传动方法,通过温控形状记忆合金弹簧来驱动磁流变液,使磁流变液的工作间隙由一面变为两面,增大了装置所能传递的转矩。基于圆盘式磁流变传动的特点,推导了装置在变面前后分别传递的转矩,探究了温度对磁流变液传递转矩的影响,并采用ANSYS有限元软件进行了磁场分析。结果表明,变面前在工作间隙h_1内的磁感应强度随半径的增大而增大;变面后在工作间隙h_2内磁感应强度先随半径增大而减小,然后再随半径的增大而增大;变面后在工作间隙h_3内磁感应强度随半径的增大而增大;装置变面后所能传递的转矩比变面前传递的转矩增大了91. 06%。
A method of temperature control variable surface magnetorheological transmission is put forward,the magnetorheological fluid is driven by means of a temperature-controlled shape memory alloy spring,so that the working space of the magnetorheological fluid from one to two,the torque that the device can deliver is increased.Based on the characteristics of disk magnetic fluid transmission,the torque transmitted separately before and after the variable face is derived,the influence of temperature on the transmission torque of magnetorheological fluid is explored,and the magnetic field analysis is carried out by ANSYS software.Results show that the magnetic induction intensity in the working space h1 increases with the increase of the radius.In the working space h2,the magnetic induction intensity decreases with the increase of radius and then increases with the increase of radius.In the working space h3,the magnetic induction intensity increases with the increase of the radius.The torque transferred by the device increases by 91.06%compared with the torque transmitted before the device.
