The characteristics of high shock resistance of a novel vibration beam structure gyroscope, namely Node-Plane Supporting Vibration Beam Gyroscopes (NPSG) were researched in this paper. NPSG is a novel rotating rate sensor, which used supporting planes located at node points instead of the supporting pins to support the vibration beam. In this paper, the sensing principle of the NPSG is presented and two types of NPSG are introduced. The dynamic equations of these two sensors are derived and the values of two kinds of gyroscopes'; shocking resistance are obtained based on the mechanics vibration principle. The research results show that the shocking resistance of the traditional Node Supporting gyroscope is below 2×102 g, while the improved Node-Plane Supporting one could reach 6×104 g. The experiments for the novel node supporting vibration beam gyroscope proved the presented principle. The designed sensor shows larger stiffness and robust resistance to shaking and striking. This paper provides the theoretical analysis and experimenting foundation for realizing the shocking resistance ability of this novel NPSG.
