AI Technical Summary
Existing technologies lack a systematic design approach to optimize the geometric parameters of hemispherical resonator anchors, resulting in long design cycles, high costs, and an inability to simultaneously meet strength requirements, suppress temperature gradients, reduce energy leakage, and achieve high sensitivity.
A hemispherical harmonic oscillator anchor size optimization method is adopted. Through a two-dimensional axisymmetric finite element model and transient thermo-field simulation, combined with classical frequency calculation, the geometric parameters of the anchor are optimized to control the temperature gradient and reduce energy leakage, thereby improving frequency and sensitivity while meeting strength requirements.
It achieves the goal of suppressing temperature gradients and energy leakage while meeting strength requirements, obtaining a reasonable frequency and high sensitivity, thus improving the performance of the hemispherical resonant gyroscope. It also has a fast calculation speed and is suitable for engineering applications.
