- 摘要:
- 490 N发动机是目前国内应用最广的卫星轨控发动机,其推力矢量的偏斜角、偏移量等参数对卫星轨道控制影响很大。转台是其推力矢量测量的常用方式。在转台中,主轴作为动架,动架与静架之间通过轴承连接定位 ,动架可沿轴向滑动。为了减小摩擦力对轴向推力标定的影响,尝试在转台上设置了激振器。通过使用激振器前后各3次试验的数据分析,发现使用激振器后主推力和比冲的标准差有所下降,表明通过激振器振动推力矢量转台是提高主推力和比冲测量精度一个值得研究的方向。但是,目前所掌握的试验数据还不够充分,需要进一步的试验来证明,而且激振器不同输出能力及频率振动对测量结果的影响也有待于深入研究。
- Abstract:
- Engine of 490 N thrust is the most widely-used orbit-control engine in Chinese satellites. The control of satellite orbit is influenced greatly by the oblique angle and offset of thrust vector. Turntable is the common thrust vector measuring device of the 490 N engine. Principal shaft is the moving support in the turntable. The moving support can slip axially by the bearing. In order to reduce the friction influence on axial thrust calibration, a vibrator was tried to set up on the turntable. Through data analysis of three tests before and after using the vibrator, it was found that the standard deviations of main thrust force and specific impulse were decreased. It is a worthy research direction to improve the measurement precisions of the main thrust force and specific impulse by using the vibrator in the turntable. However, the test data got now is not enough, and further tests are still needed to prove this result. The influences of the vibrator output force and frequency
