摘要
根据超磁致伸缩致动器(GMA)的热特性,设计了一种具有内外双层铜水管冷却结构的温度控制系统,在精确控制致动器温度的同时,有效降低了致动器的输出误差。利用ANSYS有限元分析软件对GMA温度场进行了稳态和瞬态分析,结果表明,所设计的温度控制系统能够精确控制致动器温度,大大提高了致动器的输出精度。最后搭建温控实验平台,通过无水冷和强制水冷实验可知,双层铜水管冷却结构的温控系统,大大减小了热变形对GMA输出精度的影响,温控效果十分显著。
According to the thermal characteristics of giant magnetostrictive actuator（ GMA）,a temperature control system,which has the structure of internal and external double-layer cupreous conduit,was designed. The system can control the thermal of the actuator,and thus reduce the output error of the actuator. Firstly,the steady temperature field of the GMA was analyzed by using an ANSYS finite element analysis software. It shows that the designed temperature control system can effectively control the temperature of the actuator,and greatly improve the output precision of the actuator. Then,the temperature control experiment platform was set up,and the forced water cooling experiments were conducted. The experimental results show that the temperature control system with double-layer structure of cupreous conduit can reduce the influence degree of thermal deformation on GMA output precision.
