Аннотация
Гравитационно-динамические измерения позволяют быстро получать данные о гравитационной сетке с одинаковой точностью, что важно для оперативного моделирования региональных геоидов и разработки технологий разведки ресурсов. Сверхпроводящий гравиметр – это относительный гравиметр сверхвысоких точности и пространственного разрешения. Исследование технологии динамических измерений в сверхпроводящих гравиметрах имеет большое значение для повышения точности динамических измерений гравитации. В статье рассмотрены ключевые факторы, влияющие на динамические измерения в сверхпроводящих гравиметрах. Описан принцип работы сверхпроводящих гравиметров. На основе уравнения вынужденной вибрации проведен анализ влияния ускорения вертикального возмущения носителя на результаты измерений сверхпроводящего гравиметра. Проведено исследование закона изменения выходной дифференциальной емкости, вызванного ускорением горизонтального возмущения. Изучен эффект Эотвоса сверхпроводящего гравиметра на основе анализа влияния скорости и курсового угла носителя на выходные данные сверхпроводящих гравиметров. Результаты исследований служат основой для оптимизации системы магнитной левитации сверхпроводящих гравиметров и извлечения динамических сигналов.
