陀螺转子的称重静平衡实验研究

Experimental research of measuring static balance of gyro rotor through weighing

简要说明了陀螺转子平衡的重要性,在没有适合特殊结构、小质量、高精度陀螺转子静平衡方法的前提下,对已有的一种用压力传感器来进行测力的静平衡方法进行改进,从而将只能测量二维空间的静不平衡偏心距扩展到三维空间的测量.并通过用高精度电子天平替代压力传感器,大大提高了其平衡精度,使其对小质量、高精度转子更加适用.进行了实验方案、系统的设计及简单的理论分析,最后通过实验得出实验数据、分析结果及未来展望.

Firstly, importance of gyro rotor balance is briefly introduced. Under the precondition that there are no suitable static balance methods for gyro rotors with special structure, small mass and high accuracy, an existing static balance method utilizing pressure sensor to measure force is improved. This improvement enables measurement on static imbalance of centroid offset in 2D space to extend to 3D space. Through high precision electronic balance substituting pressure sensor, balance accuracy is greatly enhanced and it is more suitable for rotors with small mass but high accuracy. Then, simple theoretic analysis and design of experimental plan and systern are conducted. Finally, experimental data, analysis result and future prospect are achieved.
