Abstract

Spring Operating Mechanism (SOM) is a dynamic mechanical system to open and close high voltage circuit breaker in electric power controlling system. For opening and closing within a few mili-seconds, it is highly sensitive with speedy transmission and great reliability. With the clearance joints, the SOM will generate high-frequency vibration due to transient impact. It has complicated wide-band nonlinear dynamic features. To save time and money for a new design and analysis of SOM system, a dynamics model of the SOM with multiple clearances and dynamic friction is established. Also, an experimental platform is built to measure the displacement of the moving contact in opening and closing. The reliability of modeling is validated through the comparison with test data. In addition, the effect of dynamic friction force on the SOM with clearance is investigated. It can be concluded that the modest increase of the friction force has a significant effect on the dynamic responses of the mechanism with clearances.
