针对传统盘式磁流变阻尼器(magneto-rheological damper,MRD)力矩密度偏低的问题，提出在转子端面构造凹结构以增加有效工作间隙长度，保持结构尺寸紧凑的同时，提高输出力矩密度。分别建立了传统盘式、矩形凹结构和弧形凹结构力矩模型，通过关键尺寸设计和定量对比分析表明，在同等条件下矩形凹结构对提升力矩密度效果更佳。为充分利用矩形凹结构的力矩增益效应，定量的分析了矩形槽位置、槽宽和槽深等关键参数对力矩密度和力矩波动的影响规律，得到了关键参数合理的优化区间。在满足目标设计力矩、线圈功率及确定的参数取值范围前提下，以体积最小为目标函数，对包括矩形凹结构的磁流变阻尼器结构参数进行了优化设计。结果表明，优化后装置力矩密度增幅达23.39%，为矩形凹结构转子阻尼器的实际设计提供了指导。
Abstract
Aiming at the problem of low torque density of traditional disk magnetorheological damper, a concave structure is proposed to increase the effective working gap length, keep the structure size compact and improve the output torque density. The torque models of traditional disc, rectangular concave structure, and arc concave structure are established respectively. Through the key size design and quantitative comparison analysis, it is shown that the rectangular concave structure has better effect on improving the torque density under the same conditions. In order to make full use of the torque gain the effect of rectangular concave structure, the influence of key parameters such as rectangular groove position, groove width and groove depth on torque density and torque fluctuation is quantitatively analyzed, and the reasonable optimization interval of key parameters is obtained. Under the premise of satisfying the target design torque, coil power and the determined range of parameters, taking the minimum volume as the objective function, the structural parameters of magnetorheological damper including rectangular grooves are optimized. The results show that the torque density of the optimized device increases by 23.39 %, which provides guidance for the actual design of the rectangular groove rotor damper.
