【摘要】 本文介绍了基于英国科学家G.H.Bryan的理论而工作的新型半球谐振陀螺仪(HRG)的工作原理。描述了半球谐振陀螺的测角过程。当陀螺壳体绕中心轴旋转时,由于哥氏效应(coriolis effect),谐振子振型相对壳体产生进动,通过控制双点激励力的幅值比,可实现振型对壳体转动角的跟踪,从而形成一种半球谐振陀螺检测角速率的方法。更多还原

【Abstract】 In this paper, the operating principle of new type of Hemispherical Resonator Gyro ( HRG ) based on English scientist G.H.Bryan’s theory, is briefly described.The process of HRG testing angular velocity is described. When the shell of Gyro rotated about its central axis, due to Corioiis effect, procession of the vibration pattern relative to the shell is produced. The vibration pattern followed the rotating angle of the shell by controlling the amplitude ratio of double points exciting forces, a new method of the HRG testing angular velocity is formed.更多还原
