Abstract

A rapid electromagnetic mechanism is designed in this paper based on a direct-current（DC）circuit breaker for rail transit

and the composition and principle of operation is described. Based on the analysis of electromagnetic field theory

using finite element analysis software ANSYS

the steady characteristics of electromagnetic mechanism and find magnetic distribution and electromagnetic force of moving iron are simulated when switching on and the influencing factor is also analyzed. Secondly

the electromagnetic force of the electromagnetic mechanism based on different current and air gap is also simulated and the distributed data of dynamic characteristics are obtained. Lastly

the dynamic characteristics of the DC circuit breaker by means of software ADAMS during switching on and off are simulated. Therefore

the mechanical characteristic of the mechanism are obtained too. Testing results indicate the above coupled method of mechanic and electromagnetic is correct and feasible.
