[0070] According to the resonant gyroscope optimization method based on co-simulation provided by the present invention, comprising: Step 1: Utilize MATLAB to write the image recognition algorithm for resonant gyroscope eigenmode recognition and the optimization algorithm for resonant gyroscope structure parameter optimization; Step 2: use COMSOL establishes a resonant gyro parametric calculation model, and outputs finite element calculation results; Step 3: Use the data interface of MATLAB and COMSOL to establish a channel for mutual data transmission, realize the call of COMSOL finite element model by MATLAB, and use the image recognition algorithm and optimization The algorithm realizes the optimization of the structural parameters of the resonant gyroscope; the image recognition algorithm analyzes and recognizes the image by extracting image features including color features, texture features, shape features and local feature points, thereby obtaining the modal information i...
Embodiment 2
[0091] Embodiment 2 is a preferred example of Embodiment 1.
[0092] refer to figure 1 The present invention relates to a resonant gyro optimization design method based on joint simulation of MATLAB and COMSOL, including two parts: MATLAB image recognition algorithm and optimization algorithm and COMSOL finite element calculation.
[0093] refer to figure 2 , COMSOLWith MATLAB is a bridge to realize the data transfer between MTALAB and COMSOL. MATLAB uses the optimization algorithm to generate m optimization variables according to the calculated fitness value. The size of m is determined by the number of resonant gyro structure parameter variables. Pass the optimization variables to COMSOL, COMSOL rebuilds the finite element model according to the optimization variables, and calculates the quality factor, frequency difference, and eigenfrequency of n eigenmodes, and the size of n is determined by the resonant gyroscope’s working mode. MATLAB uses the image recognition algor...
