双线圈旁置式新型磁流变制动器的设计与优化
Design and optimization of a novel magnetorheological brake with double coils placed on the side housing
摘要
Abstract
In order to improve the braking torque of conventional hybrid magnetorheological brake (MRB)with single coil,a novel MRB with double coils placed on the side housing is proposed. The novel structure enabled it to have larger area of controllable interaction face in cylindrical surface of brake disk and a larger braking torque.The torque model and design method of mag-netic circuit of the novel MRB were proposed based on Herscher-Bulkley model.And then a multi-obj ective optimization under the specific condition was conducted.Comparative analysis be-tween conventional and novel MRB demonstrated that under the condition of the same volume, the novel MRB had a larger braking torque.And in order to make full advantage of the rheologi-cal properties of MRF and get a more compact structure,the width of the brake should be 80-100 mm and the reasonable range of the length-width ratio should be 0.6-1.2.After optimization,the braking torque was increased by 1 1% in the situation which its weight basically remained un-changed.The results can be taken as reference to the design of MRB.关键词
