Simulated Prediction of Structural Asymmetry for Glass Blown Micro Shell Resonators

This paper reports modeling process and a simulated prediction of structural asymmetry for glass blown micro shell resonators. Alignment deviation between center of blowtorch and forming mold is considered as the main undesirable condition. Geometric error including height variation along the circumference is analyzed based on three-dimensional model of fused silica substrate and forming mold. Simulation results indicate that the geometric error increases linearly as the increase of the alignment deviation and uniform temperature field is necessary. The results provide reference for fabrication of highly symmetric resonators.
