A new type of magnetorheological fluid drive disk is designed to solve the problem of high-power magnetorheological fluid transmission heat dissipation. The characteristics of the flow field and temperature field of high power MR fluid transmission devices are analyzed, and the influence of factors such as rotating speed, inlet velocity, inlet position, diameter, and number of magnetic columns on the flow field are investigated. The experimental results show that the device has good heat dissipation performance and can transfer high-power torque.
Aiming to solve the problem of high-power magnetorheological fluid transmission heat dissipation, a new type of magnetorheological fluid drive disk is designed. The characteristics of the flow field and temperature field of high power MR fluid transmission devices are analyzed. Meanwhile, the influence of factors, such as rotating speed, inlet velocity, inlet position, diameter and number of magnetic columns, on the flow field are also investigated. Furthermore, the distribution characteristics of the ultimate slip power and the transient temperature field are obtained. The experimental platform of an MR fluid transmission device was established, and the torque transfer performance and heat dissipation performance were tested. The experimental results show that the device has good heat dissipation performance and can transfer high-power torque.
