<p>The present invention relates to the balancing of hemispherical resonators and may be used in instrument construction technology during the production of navigation systems for aircraft, ships, spacecraft or controlled drilling heads. The purpose of this invention is to increase the balancing precision using a balancing method that comprises the following steps: attaching the resonator behind a header; mounting a piezo-electric sensor on the free end of the header; generating vibrations; measuring the voltage of the sensor for the different orientations of the standing wave in the resonator; estimating the unbalance mass by mathematically processing the experimental data thus obtained; and removing the unbalance mass from the extended surface of the resonator using an ion beam. This method for balancing resonators allows for a balancing precision of up to 30 micrograms while maintaining a high acoustic quality factor of the resonator (107 or more), and can also be used for balancing resonators that do not include balancing dents.</p> |
