Shock Dynamics Analysis of Opening Process of Spring Mechanism for Circuit Breaker

In order to accurately evaluate the strength and stiffness of the key components of the spring mechanism for circuit breakers under strong impact load conditions, and provide strong data support for product design and structural optimization, the impact dynamics analysis method is used to model and simulate the spring mechanism. The dynamic stress test data is used to verify the accuracy of the simulation, and the strength of the key components under impact conditions is obtained. The influence of different stiffness frames on the output shaft offset is analyzed.
