- 摘要:
- 微小推力测量技术是微推进器研制的关键技术之一,是微小卫星技术发展的重要支撑。为了发展更高精度的测量系统,基于双光束干涉原理,提出了一种新的高精度光学微小推力测量方法,设计并搭建了一套测量微小推力的实验装置。进行了三次标定和测量实验,探索和总结出微推力测量的经验和方法,并对测量系统进行改进。实验结果表明,该测量系统使用方便,能获取实时推力曲线,最大测量误差1.86%,测量精度已达到现有推力架的测量精度,但没有达到双光束干涉原理的理论精度要求,在未来有较大的提升空间。
- Abstract:
- The micro-thrust measurement technology plays a key role in micro-thruster development, which is the essential technology of micro-satellite. To develop high-precision measurement system, a new high-precision optical micro-thrust measuring method based on the principle of double-beam interference was proposed, and a micro-thrust experimental device was founded as well. Through three different calibration and measurement tests, some experiences and methods of micro-thrust measurement were obtained and some measuring facilities were improved. The experimental result shows that the measurement system can acquire the real-time thrust curve and is convenient for operation. Its maximum measurement error is 1.86%. The mearuring accuracy is up to the precision of existing thrust-frame measuring equipment. However, the measuring precision is still below the theoretic precision of
