摘要/Abstract

摘要： 为研究磁流变制动器的制动时间与工作间隙的关系，基于Bingham理论模型并结合ANSYS磁场仿真推导出磁流变制动器制动时间的计算公式，基于此公式计算出不同工作间隙下不同转动角速度对应的制动时间.利用间隙可调式磁流变制动器进行不同工作间隙下制动时间与转动角速度的测量实验；对比理论值与实验值，验证了理论计算公式的准确性，并从理论与实际上证明了制动时间与工作间隙呈线性增长关系.不同励磁电流下制动时间的测量实验证明了同一工作间隙下制动时间与电流为非线性关系.

关键词: 磁流变制动器, 制动力矩, 工作间隙, 转动角速度, 制动时间

Abstract: To study the relationship between the braking time and the working gap of the magneto-rheological brake (MRB)， the calculating formula of braking time on the MRB was deduced based on the Bingham theory model and the ANSYS magnetic field simulation. The braking time corresponding to different rotating angular velocities under different working gaps was calculated based on the formula and the measuring test of braking time and rotational angular velocity under different working gaps was carried out based on MRB with adjustable working gap. Comparing the theoretical value with the experimental one， the braking time is shown to increase linearly with the working gap， and the correctness of the theoretical calculation formulas was verified. The braking time under different currents was measured， and the nonlinear relationship between the braking time and current under the same working gap was proved.

Key words: magneto-rheological brake, braking torque, working gap, rotating angular velocity, braking time
