摘　　要：航天器太阳翼、天线等大部件地面展开过程中需进行重力卸载,目前应用最为广泛的是二维平面滑轨式零重力展开架。针对二维平面滑轨式零重力展开架占用空间大、调平效率低、适用工况相对单一等缺点,提出了一种悬挂在厂房高空中、可伸缩的高精度自动调平装置,该装置可为二维平面滑轨提供安装平台,快速实现二维平面滑轨的高度定位和水平度精调。首先对系统组成进行了介绍;其次,对装置的升降原理、水平度精调原理和消除间隙原理进行了阐述,可确保平台可实现高度调整和水平度调整要求;再次,对整个装置的自由度进行了分析,并给出了调姿策略;最后,完成了装置的安装和测试。结果表明:调平装置可快速实现高度升降和水平度自动调平,升降精度优于0.3mm,调平精度优于0.028mm/m。The deploying process of large components such as spacecraft’s solar wing and antenna need uninstall the gravity.At present,the device which is most widely used is zero-gravity unfolding rack in type of two-dimensional sliding rail.But this zero-gravity unfolding rack has the disadvantageslarge space occupation,low leveling efficiency and relatively single applicable conditions.So one high-precision automatic leveling device which can be suspended high in plant and can be extended is proposed.The device can be used as an installation platform of two-dimensional plane sliding rail and rapidly realizes height determination and fine tuning of levelness.Firstly,it is the introduction to system composition;secondly,description is carried out for principles of lifting,fine tuning of levelness and gap elimination,which can meet the requirement of height adjustment and levelness adjustment;thirdly,the degree of freedom of the whole device is analyzed and the strategy is given;finally,complete installation and testing of the device.The results show that:the leveling device can achieve high lifting and leveling automatically,the lifting precision is above 0.3mm and the leveling precision is above 0.028mm/m.
