摘要
FAST是目前世界上最大的射电望眼镜,它的反射面是靠液压促动器对伸缩缸带动下拉索调节反射面形,实现全偏振及宽频带观测。通过对目前比较成熟的两种液压促动器的液压技术进行探讨,从而找出比较符合FAST液压促动器要求的液压技术,以供从事FAST项目工程的研究、施工等工作提供技术参考。
FAST（ Five-hundred-meter Aperture Spherical Telescope）is currently the world＇s largest radio telescope,the reflecting surface of which is by the hydraulic actuator of the telescopic cylinder driven cable adjustment reflector.To achieve full polarization and broadband observation,based on the two kinds of hydraulic mature promote discussion of pneumatic and hydraulic technology,so as to find out the comparison with FAST hydraulic actuator hydraulic technology is required,in order to offer a reference for FAST project engaged in research and construction work to provide technical.
