摘要
陀螺仪广泛应用于航空航天等领域,其动平衡精度要求较高,但调整较为繁琐且效率不高。为了解决某型号陀螺仪动平衡调整难题,针对陀螺仪自身结构特点及高精度、高稳定性的要求,采用质心平移法研制了调整分辨率达到0.2μm的陀螺仪动平衡自动化调整装置,并用此装置进行了动平衡调整实验。实验结果表明,通过三次调整后,剩余不平衡量为14.3mg·mm,满足精度要求。同时通过实验验证了质心平移法调整的合理性及可行性,调整效率显著提高。
Gyroscope is w idely used in aerospace and other fields,w hose dynamic balancing precision demand is higher. But the adjustment is complicated and the efficiency is inefficient. In order to solve a certain type of gyroscope dynamic balancing adjustment problem,according to the structural characteristics of this gyroscope and the requirements of high precision and stability,an automated dynamic balancing adjustment device w as developed by the method of centroid translation and its resolution w as 0. 2μm. The dynamic balancing experiment w as done by the device. The experimental result show s that non-dynamic balancing quantity is 14. 3mg ·mm w hich satisfies the precision requirement. The rationality and feasibility for the method of centroid translation w as velidated by this dynamic balancing adjustment experiment. The adjusting efficiency w as improved significantly.
