摘要

基于磁流变液的流变特性，设计了一款盘面加工有矩形凸块的盘式磁流变制动器，推导了其制动力矩计算公式，基于Matlab/simulink建立了仿真模型，不断优化矩形凸块的尺寸参数。仿真结果表明，当加工有12个宽度为2 mm、深度为1.5 mm的矩形凸块时，产生的制动力矩达到626 N·m，比未加工凸块时的制动力矩提高了31.5%，表明设计的磁流变制动器可以有效地提高制动力矩。

Abstract

Based on the rheological properties of MRF，a disc-type MR brake with rectangular bump is designed，and the calculation formula of its braking torque is derived. The simulation model is established based on Matlab/Simulink， and the size parameters of rectangular bump are continuously optimized. The simulation results show that when there are 12 rectangular bumps with a width of 2 mm and a depth of 1.5 mm， the braking torque is 626 N·m， which is 31.5% higher than that of the bumps without machining. It shows that the designed MR brake can effectively improve the braking torque.
