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。
To simulate the satellite solar panels in low-gravity space environment testing, often by hanging to achieve. In view of the current domestic follow-up system can not meet the real-time dynamic follow-up, easy to produce vibration and other shortcomings, the article presents a simple and easy to follow the measured linear motion program. Based on the frictionless relative motion of the flotation module, the proposed scheme solves the technical difficulties of maintaining the vertical center of gravity of the suspension point and the sailboard during the following movement of the following system by using the long-distance linear slide and the electromagnetic force device. Combined with hardware and software control system, the ultimate realization of long-distance high-precision non-damped linear motion follow the system design. Experiments show that the designed follow-up system fully meets the testing requirements of spacecraft.
