摘要
对卫星太阳能帆板进行模拟太空低重力环境测试时,常通过吊挂跟随来实现。针对目前国内相应的跟随系统无法满足实时动态跟随、易产生震动等缺点,文章提出了一种简单易行的被测件直线运动跟随方案。该方案基于气浮组件的无摩擦相对运动特性,利用长距离直线滑轨及电磁力装置,解决了跟随系统在水平跟随运动过程中保持吊点与帆板质心铅垂的技术难点。结合软硬件控制系统,最终实现长距离高精度无阻尼直线运动跟随系统的设计。试验表明,所设计的跟随系统完全符合航天器的测试要求。
The test to satellite solar energy canvas plate in the condition of simulated space low grevity environment is usually managed by suspended following system. Because of the bad real-time dynamic following performance and easily caused vibration of current following systems, the paper proposed a simple and practicable tested linear movement following method. The method which based on the characteristics of dampingless relative movement in gas floated device, had made use of long length slide track and electromagnetic force device, to solve the goal of following system controlled as near as solar energy canvas plate in horizontal following movement. Combined with soft-hardware control system automated control system, the paper successfully designed a high precision following system which fulfilled the long-travel dampingless linear following movement. The test results show that the designed following system splendidly meets with the test demand of spacecraft.
