Cupped wave gyro’s mathematical modeling is derived via Hamilton principle, and the displacement equations and the nature frequency of gyro is determined by Galerkin method. Based on the modeling analysis and finite element method, the parameters of structure are optimized. The paper provides a reference in the design and fabrication of cupped wave gyro.

This paper presents a framework to analyze the vibration characteristics of mounting plates for molded case circuit breakers (MCCB). Two different three-dimensional models for mounting plate I and II are established in ANSYS Workbench simulation platform through reasonable simplifications. The preceding six-order natural frequencies are obtained by means of modal analysis. Based on the experimental data of modal analysis, random vibration analysis of mounting panel I and II is conducted. It is concluded that mounting plate I is easy to deform permanently when its 3δ stress exceeds the yield limit of material, while mounting plate II meets the strength requirements and is better suited to test requirements.
