摘　　要：针对磁性液体在太空微重力环境下的表面不稳定性问题,基于磁性液体表面不稳定性与其磁响应特性的关系,运用OPC(OLE for Process Control)通信技术设计出一种新型磁性液体性能研究装置。研究装置由硬件和软件两部分组成,硬件包括计算机、控制面板、可编程逻辑控制器、电压调节模块和电磁铁等,软件部分主要采用OPC实现MATLAB与S7-200PLC的通信,可通过三种模式调节磁场来研究磁性液体的表面不稳定性,装置运行稳定,实现对磁性液体表面不稳定现象的控制及动态展示。Ferrofluids have surface instabilities in microgravity. A novel experimental device to study the property of ferrofluids including the hardware and the software was designed by OPC( OLE for Process Control) technique based on the relationship between the surface instabilities and the response to applied magnetic field of ferrofluids. The hardware of device mainly included the personal computer,the control panel,the programmable logic controller( PLC),the voltage control module and the electromagnet. OPC technique was used to enable the communication between MATLAB and S7200-PLC,thus the magnetic field could be adjusted in three modes to study the surface instabilities of ferrofluids. The results showed that the device run smoothly,the control and dynamic display of surface instabilities of ferrofluids were realized.
