Abstract Finite element model of the drive system for a circuit breaker was built. The measured displacement is added on the finite element model. The deformation and von-Mises stress of key parts in the drive system are calculated based on explicit finite element method. The finite element model is validated by experimental results. The results indicate that the deformation of the connecting rod is mainly caused by the inertial force. Then the connecting rod is optimized to reduce the deformation and the von-Mises stress.

Key words： circuit breakers drive system explicit finite element optimization
