摘要
热效应下形状记忆合金驱动的圆盘式磁流变液变速传动装置是一种输出转速随温度改变而迅速变化的传动装置。较之在高温下工作的离合器,该变速传动装置提高了磁流变液的使用寿命。针对该变速传动装置,分析了工作原理;基于磁路的欧姆定律,建立了磁路理论模型;应用ANSYS软件对该变速传动装置的磁路理论模型进行仿真并通过迭代计算验证了仿真模型的正确性。通过磁路理论模型的仿真,得到了不同圆盘材料、工作间隙大小对工作间隙沿径向磁感应强度的影响关系,并分析了隔磁环对磁场强度和输出转矩的影响。
The disc- type magnetorheological fluid transmission device driven by shape memory alloy under thermal effect is a transmission device that its output speed rapidly changes with the temperature changes.Compared with the clutch working with high temperature,the transmission device extends the service life of the magnetorheological fluid. Aiming at transmission device,the working principle is analyzed,the magnetic circuit theoretical model is established based on Ohm's law of magnetic circuit. The magnetic circuit theoretical model of transmission device is simulated by ANSYS software and the correctness of the simulation model is verified by the iterative calculation. The influences of different disc material and working gap size along the radial magnetic induction intensity are obtained by simulation of magnetic circuit,moreover the influence of isolation ring to the magnetic field intensity and output torque is analyzed.
