The properties of small size, low noise, high performance and no wear-out have made the hemispherical resonator gyroscope a good choice for high-value space missions. To enhance precision use in tasks with large angular velocities accelerations, this paper investigates standing wave precession non-ideal under nonlinear high-intensity dynamic conditions. Based on thin shell theory elasticity, model is established by using Lagrange’s second kind equation. Then, equivalently transformed into simple harmonic vibration point mass two-dimensional space, which analyzed method averaging that separates slow variables from fast variables. results reveal taking terms about square velocity acceleration equation account can weaken influence 4th component defect drift, extent weakening effect varies dimensions defects, very important steering development high-precision gyroscope.
