摘要
为了提高制动器分闸过程的动态响应特性,针对现有电磁制动器存在的问题,该文提出了一种可快速分闸的、具有混合励磁结构的新型电磁制动器。为减小漏磁对制动过程动态响应的不利影响,降低设计难度,提出了新的解耦磁路。为满足大多数电磁铁动态特性分析的需求,在推导电磁制动器等值电路模型及电磁场有限元分析的基础上,研究建立了基于场路结合的制动器的静态以及动态特性分析模型。该样机测试结果表明该制动器性能符合预期要求。
In order to improve the dynamic response characteristics of brake break-brake process,aiming at the existing problems of electromagnetic brake,a new type of electromagnet brake with fast break-brake and hybrid excitation structure is proposed.In order to reduce the adverse effect of magnetic leakage on dynamic response of braking process,and reduce design difficulty,a new decoupling magnetic circuit is proposed.To meet the requirements of most electromagnet dynamic characteristics analysis,on the basis of derivation of equivalent circuit model of electromagnetic brake and finite element analysis of electromagnetic field,static and dynamic characteristic analysis model of brake based on the combination of field road is established.The test results show that the brake performance meets the expected requirements.
