Abstract:

In order to solve the problems of existing magnetorheological brakes with large size, small braking torque and poor heat dissipation performance,based on the contradiction analysis method and conflict matrix of TRIZ, a novel comb-type magnetorheological brake applied to electric vehicles was designed, and the braking torque and temperature field simulation mathematical model were established. The various performance indicators of the brake were verified through simulation and experimental study. The results show that the magnetic field of comb-type magnetorheological brake is concentrated in the comb-type brake disk part, and the maximum braking torque increases gradually with the increasing of input current, the saturation current is as 3.6 A, the braking torque is as 334 N·m, and the torque/volume ratio is as 65.215 kN/m2. The heat of the brake is mainly generated in the comb-type brake disk part, which gradually spreads from the brake disk to the casing and the shaft body with the passage of time. The paper verifies that the novel comb-type magnetorheological brake has better heat dissipation performance when achieving continuous braking.

摘要:

为解决现有磁流变制动器体积大、制动力矩小、散热性能差的问题,利用TRIZ工具中的矛盾分析法及冲突矩阵设计一种应用于电动汽车的新型梳式磁流变制动器,并建立了其制动力矩及温度场仿真数学模型。通过数值仿真与实验研究,验证了制动器的各项性能指标。研究结果表明,梳式磁流变制动器磁场主要集中在梳式制动盘部分,其最大制动力矩随着输入电流的增大而逐渐增大,得到的饱和电流为3.6 A、制动力矩为334 N·m、力矩/体积比为65.215 kN/m2。制动器热量主要产生于梳式制动盘区域,随着时间的推移,热量从制动盘开始逐渐向壳体及轴体扩散。研究验证了新型结构的梳式磁流变制动器在实现连续制动时具有较好的散热性能。
