研制了转子具有圆柱体结构的旋转式磁流变阻尼器,转子的两个端面和圆柱面均为工作面,设计了适用于磁流变阻尼器的永磁密封装置,利用阻尼器内的磁流变液实现了动密封。应用有限元法对阻尼器模型进行了电磁场分析,结合有限元分析结果与磁流变液的本构关系,对磁流变阻尼器的力学性能进行了仿真研究。开发了用于磁流变阻尼器的驱动器,实现了应用工控机对阻尼器的屈服力矩进行控制。在此基础上,建立了阻尼器控制实验系统,对阻尼器的屈服力矩控制进行了实验研究。
A rotary magnetorheological damper with a cylindrical structure is developed. Both end faces of the rotor and the cylindrical surface are working faces. A permanent magnet sealing device suitable for a magnetorheological damper is designed. The magnetism in the damper Rheological fluid to achieve a dynamic seal. The finite element method was used to analyze the electromagnetic field of the damper model. Based on the finite element analysis and the constitutive relation between MR fluid and the rheological fluid, the mechanical properties of MR damper were simulated. Developed for the magnetorheological damper actuator, the realization of the application of IPC damping force of the damper to control. On this basis, the damper control experiment system is established and the yield moment control of the damper is experimentally studied.
